Item Evaluación del sistema de radiación UV-C como estrategia de control microbiológico en mesas de consulta y jaulas en clínicas veterinarias.(Universidad Santiago de Cali, 2026-06-11) Hernandez Suarez,Delia Karime; Cardona Grisales,Dahianna Andrea; Rodríguez Neira, Cristian Fernando (Director); Duque Zapata, Juan Diego(Director)ABSTRACT: Microbiological control is a necessary component of any veterinary practice to protect the safety of personnel and animals and to minimize the risk of nosocomial infections. The purpose of this study is to evaluate the effectiveness of ultraviolet C (UV-C) light as a means of disinfecting hospital cages in a veterinary clinic in Cali, in contrast to the traditional method of using sodium hypochlorite. A longitudinal experimental design was used, and sampling was carried out with swabs that were analyzed in a laboratory by culturing the swabs on nutrient agar followed by incubation for 24-48 hours at 37 degrees Celsius to qualitatively determine whether there was bacterial growth or not. The results indicated that the control samples had bacterial growth; there was a partial reduction in bacterial growth with the use of sodium hypochlorite; and there was a relationship dependent on the exposure time to UV-C, which resulted in the total elimination of microbial growth after 10 minutes. The results of this study contributed to the knowledge that UV-C light is a highly effective means of disinfecting veterinary hospitalization cages and that there are operational and environmental benefits to using UV-C light disinfection instead of traditional chemical disinfection methods, and, therefore, it would be a good addition to the biosecurity measures used in veterinary hospitals.Item Efecto del cambio de temperatura ambiental en la dinámica poblacional de Aedes aegypti y en la transmisión de enfermedades zoonóticas en la zona amazónica de Brasil. Revisión sistemática(Universidad Santiago de Cali, 2026-06-24) Calceto Valencia, Gabriel; Guarin Patarroyo, Camilo(Director)Introduction: Climate change, characterized by rising global temperatures, poses significant challenges to public health, particularly in ecologically sensitive regions such as the Brazilian Amazon. Methods: A systematic literature search was conducted using the selected databases, following PRISMA guidelines. Experimental, epidemiological, and modeling studies were included if they analyzed the relationship between temperature and biological parameters of the vector (reproduction rates, development, survival) and/or the incidence of arboviruses (dengue, Zika, chikungunya) in the Brazilian Amazon region or under relevant experimental conditions. Opinion articles, non-systematic reviews, and studies focused exclusively on other regions without relevant data for the Amazon were excluded. Results: A total of 28 studies were included in the qualitative synthesis. The evidence consistently demonstrates that temperature is a key determinant in the biology of Aedes aegypti. Increasing temperature significantly accelerates larval development, shortens the life cycle, and increases female fecundity, leading to higher vector population density. However, extreme temperatures (>32–35°C) may have deleterious effects, increasing mortality and reducing survival. Likewise, modeling studies project an expansion of climatically suitable areas for Aedes aegypti in southern Brazil, while in warmer regions such as the Amazon, extreme temperature increases could paradoxically render some areas thermally limiting during certain times of the year. Conclusions: The reviewed evidence confirms that environmental temperature change is a key driver of Aedes aegypti population dynamics in the Brazilian Amazon. Warmer temperatures, within certain limits, accelerate its life cycle and enhance its vectorial capacity, increasing the risk of arbovirus transmission. Climate projections indicate a complex scenario in which some areas may become higher-risk zones, while others may experience seasonal reductions in transmission potential due to extreme heat. These findings underscore the urgent need to integrate climate, entomological, and epidemiological surveillance to develop early warning systems and adaptive, region-specific control strategies for the AmazonItem Terapias y aportes del Laboratorio Clínico en el Síndrome de Disfunción Cognitiva en perros Geriátricos; Revisión Sistemática(Universidad Santiago de Cali, 2026-06-11) Ríos Acevedo, Johana Andrea; Ríos Acevedo, Jhon Jairo (Director); Correa Toro, Nelson William (Director)This systematic review aimed to compile and analyze the most recent scientific evidence (2020–2025) on the comprehensive management of Canine Cognitive Dysfunction Syndrome (CCDS) in geriatric dogs, encompassing pharmacological and non-pharmacological therapeutic interventions, as well as the contributions of the clinical laboratory to diagnosis and follow-up. A total of 336 articles were retrieved, 31 of which met the inclusion criteria and were analyzed and discussed. The reviewed studies demonstrated that pharmacological therapies, such as monoamine oxidase type B inhibitors (selegiline), antioxidants, and nutraceuticals with omega-3 fatty acids, can improve cognitive function and quality of life in older dogs. Likewise, non-pharmacological interventions, including cognitive stimulation, environmental enrichment, and physiotherapy, showed synergistic effects when applied in combination with medical treatment. On the other hand, there was a growing interest in the role of the clinical laboratory in the differential diagnosis of CCD, through the use of serum and cerebrospinal fluid biomarkers (NfL, GFAP, β-amyloid), as well as advanced imaging techniques (MRI and PET) for the detection of brain atrophy and associated vascular abnormalities. These advances contribute not only to improving diagnostic accuracy but also to therapeutic monitoring and the differentiation of other neurological pathologies. Taken together, the evidence analyzed highlights the importance of a multidimensional approach that integrates clinical medicine, neuroimaging, and molecular biology in the management of CCD, strengthening its relevance as a comparative model for human Alzheimer's disease.Item Más allá de los resultados hormonales: Revisión sistemática de la variabilidad clínica y los errores más comunes al diagnosticar hipotiroidismo canino(Universidad Santiago de Cali, 2026-05-05) Ruiz Torres, Isabella; Cardona Tobar, Karen Melissa (Directora)Canine hypothyroidism is one of the most frequently diagnosed endocrinopathies in veterinary practice; however, its identification remains a challenge due to the wide clinical variability and the influence of multiple factors that can alter hormonal parameters without reflecting primary thyroid disease. This systematic review aimed to analyze the main biases and errors affecting the diagnostic interpretation of hypothyroidism in dogs, considering both the biological variability and the methodological limitations of studies published between 2020 and 2025. Searches were conducted in PubMed, Scopus, ScienceDirect, Web of Science, and Google Scholar, following PRISMA guidelines. Original studies in English or Spanish that used thyroid hormone tests and described diagnostic criteria applied in clinical canine populations were included. The results revealed heterogeneity in study designs, analytical methodologies, and criteria used to define hypothyroidism. The most frequent biases included non-random selection of animals referred for nonspecific signs, lack of confirmation through complementary tests (e.g., free T4 by equilibrium dialysis), and insufficient control for confounding factors such as systemic diseases, glucocorticoid use, breed variations, or the influence of metabolic status. Inconsistencies were also identified in hormonal measurement methods and in the references used to interpret total T4, free T4, and canine TSH. Overall, the evidence demonstrates that overdiagnosis and misdiagnosis stem primarily from exclusive reliance on individual parameters, isolated interpretation of clinical signs, and the absence of standardized diagnostic protocols. The need to adopt integrated diagnostic approaches and improve methodological quality to reduce variability and increase diagnostic accuracy in veterinary practice is emphasized.Item Precisión diagnóstica del hemograma automatizado y el frotis de sanguíneo en la detección de anemia hemolítica inmunomediada en perros: revisión sistemática(2026-05-28) Gómez Bravo, Herli Yurani; William Correa, Nelson (Director)Immune-mediated hemolytic anemia (IMHA) is one of the most serious hematological conditions in dogs, characterized by antibody-mediated destruction of red blood cells. This systematic review aimed to evaluate the diagnostic accuracy of the automated complete blood count (CBC) and peripheral blood smear (PBS) in dogs with IMHA, following PRISMA guidelines. Electronic databases (ScienceDirect, PubMed, Scopus, among others) were searched with a time restriction of 2013–2025 and limited to Spanish, English, and Portuguese publications. Of 20 initially identified studies, 10 met the eligibility criteria. Results show that the automated CBC is essential for quantifying anemia severity and regenerative response through parameters such as PCV/hematocrit and reticulocyte count, although it lacks specificity to confirm an immune-mediated origin when used alone. The PBS complements this limitation through the detection of significant spherocytosis and persistent autoagglutination; these findings are supported by quantitative sensitivity and specificity data. Of the included studies, 83.3% reported combined use of both tests as a diagnostic criterion. However, incorporation of the evaluated parameters into the reference standard generated incorporation bias, limiting formal calculation of consolidated diagnostic accuracy. It is concluded that the sequential integration of the automated CBC and PBS constitutes the most efficient and cost-effective initial strategy for the presumptive diagnosis of IMHA in dogs; a three-phase diagnostic algorithm based on the reviewed evidence is proposed.Item Abordaje diagnóstico y terapéutico del Síndrome de Addison en caninos: Revisión sistemática(Universidad Santiago de Cali, 2026-05-25) Pantoja Rodriguez, Jose William ; Cardona Tobar, Karen Melissa (Directora)Addison’s disease or canine hypoadrenocorticism is an uncommon endocrinopathy characterized by deficient secretion of glucocorticoids and mineralocorticoids, leading to metabolic and electrolyte disturbances of variable severity. This systematic review aimed to identify the diagnostic criteria and the most effective therapeutic strategies for the clinical management of Addison’s disease in dogs. A structured literature search was conducted across scientific databases following the PRISMA 2020 guidelines. After applying inclusion and exclusion criteria, 50 studies addressing diagnostic, therapeutic, and prognostic aspects of the disease were included. The results demonstrated that the ACTH stimulation test remains the diagnostic gold standard, while basal cortisol measurement and the sodium-to-potassium ratio serve as complementary tools for clinical suspicion and initial screening. Regarding treatment, the combination of desoxycorticosterone pivalate (DOCP) and prednisolone was associated with improved clinical and electrolyte control due to its ability to more consistently restore mineralocorticoid and glucocorticoid homeostasis, reducing serum sodium and potassium variability and improving long-term clinical stability. In conclusion, early diagnosis and individualized treatment significantly improve prognosis and patient quality of life, highlighting the need to strengthen standardized evidence-based clinical protocols.Item Prevalencia de bacterias de interés clínico veterinario en superficies de preparación y manipulación de alimentos en la cocina de un zoológico en Colombia, 2025(Universidad Santiago de Cali, 2026-05-20) Loaiza Buitrago, Diana Fernanda; Salazar Sánchez, Vanessa; Duque Zapata, Juan Diego (Director); Peña Stadlin, Juliana (Director)The presence of bacteria of veterinary clinical interest was assessed on food preparation surfaces and food handlers in the kitchen of a zoo in Colombia during 2025. The objective was to determine their prevalence and distribution in different areas. A descriptive cross-sectional study was conducted, involving sampling of surfaces, utensils, and food handlers, followed by microbiological analysis using conventional techniques. The results revealed the presence of Pseudomonas spp., Klebsiella spp., and Escherichia coli on surfaces, most frequently in the meat processing area, and a predominance of Staphylococcus spp. on food handlers. No Salmonella spp. were detected. It is concluded that conditions exist that favor the presence of microorganisms in the evaluated environment, with food handling standing out as a key factor in the dynamics of microbiological contamination.Item Estrategias de manejo nutricional en perros con insuficiencia renal crónica y su impacto en la calidad de vida y el estado clínico(Universidad Santiago De Cali, 2026-05-22) Almeida Hincapie, Sara Valentina ; Gutierrez, Juan David (Director)Chronic kidney disease (CKD) is one of the leading causes of serious illness in dogs, affecting their health and life expectancy. Proper nutritional management plays a crucial role in improving their well-being and increasing their life expectancy. This descriptive and analytical study focuses on exploring how nutritional strategies can influence dogs with CKD. Its objective is to identify which dietary practices could improve their quality of life and delay disease progression. Through a detailed review of recent scientific studies, the specific nutritional needs of dogs with CKD will be analyzed, as well as the effectiveness of key nutrients such as protein, phosphorus, and essential fatty acids. It will also explore how these nutrients impact dogs' quality of life and kidney function, as well as the relationship between specialized diets and clinical signs of the disease, such as urinary problems. This research aims to provide valuable information for both veterinarians and pet owners, facilitating the implementation of dietary interventions that help treat CKD more effectively and improve dogs' long-term quality of life.Item Efectos de la suplementación dietaria con curcumina sobre parámetros productivos en pollos de engorde: revisión sistémica(2025-03-30) Rojas Mendoza, Daniela; Gutiérrez Gómez, Juan David (Director)The poultry industry faces constant challenges related to variability and inefficiency in important production parameters, such as daily weight gain and feed conversion, which negatively impacts the sector's profitability. Due to this need, poultry producers have been tasked with seeking natural alternatives that contribute to the aforementioned parameters. Therefore, this study aimed to analyze the scientific evidence from the last ten years (2015-2025) on the effects of dietary curcumin supplementation in broiler chickens, in order to determine its impact. A systematic review was conducted to identify, select, and compare studies and results that evaluated curcumin versus conventional diets. The results of the review indicated that curcumin represents a viable nutritional strategy to optimize performance. The majority of the reviewed literature reported an increase in daily weight gain (DWG) and an improvement in feed conversion (FC) in supplemented birds. However, the magnitude of this benefit was found to vary, critically depending on the form of supplementation (highly bioavailable formulations, such as nanocurcumin, being more effective) and the context in which the poultry were used. It was concluded that curcumin was established as a promising natural additive with high potential to strengthen the efficiency and profitability of the poultry production system. Formulation standardization is recommended to maximize its commercial impact.Item Estrategias nutricionales del caballo criollo colombiano con síndrome metabólico equino: revisión sistemática(Universidad Santiago de Cali, 2026-03-30) Campo Martínez, Isabella; Perilla Amaya, Jorge (Director)Nutrition is a determining factor in maintaining the health and performance of equines, especially in the Colombian Criollo Horse, a breed of great genetic and functional importance in the country. The inappropriate use of concentrates and supplements can cause metabolic and digestive imbalances, including insulin resistance, laminitis, and obesity, significantly affecting the well-being and performance of these animals. This study aimed to analyze nutritional strategies aimed at improving metabolic health and preventing disorders associated with energy excess in this breed. A narrative literature review was conducted according to PRISMA guidelines and based on recent scientific publications that addressed the effects of different feeding practices on equine metabolic physiology. The results showed that diets high in concentrate and low in fiber increased the risk of developing metabolic disorders, while forage-based diets favored digestive, endocrine, and muscular homeostasis. Furthermore, the need to establish nutritional guidelines adapted to the tropical context and physical activity of the Colombian Criollo Horse was identified. In conclusion, the research highlighted that equine nutrition should be understood as an essential component of overall health and not solely as a means of energy supply, promoting veterinary advice in the formulation of balanced diets that guarantee the well-being, performance, and sustainability of this species.Item Alteraciones reproductivas en yeguas con disfunción de la pars intermedia de la glándula pituitaria (PPID)(Universidad Santiago de Cali, 2026-05-22) Garcia Alvarez, Isabella; Perilla Amaya, Jorge (Director)Pituitary pars intermedia dysfunction (PPID), commonly known as equine Cushing’s syndrome, is a prevalent endocrinopathy in geriatric horses that significantly affects the reproductive health and efficiency of mares. The objective of this study was to analyze the impact of PPID on reproductive function in aged mares through a documentary review of specialized scientific literature. Studies related to the pathophysiology of the disease, hormonal mechanisms involved, and their effects on estrous cycle regulation, conception, and embryonic survival were examined. Evidence indicates that the dopaminergic neurodegeneration characteristic of PPID leads to hypersecretion of proopiomelanocortin-derived peptides, including ACTH, α-MSH, and β-endorphin, resulting in metabolic, immunological, and endocrine alterations. These changes disrupt the hypothalamic–pituitary–gonadal axis, leading to irregular estrous cycles, anovulatory follicles, decreased conception rates, early embryonic loss, and increased susceptibility to persistent endometritis. Additionally, insulin resistance and equine metabolic syndrome associated with PPID contribute to alterations in follicular dynamics and reduced oocyte quality. In conclusion, PPID represents a major factor in the reproductive decline of geriatric mares, highlighting the importance of early diagnosis and appropriate management strategies to improve reproductive efficiency, animal welfare, and the sustainability of equine breeding systems.Item Revisión sistemática sobre las causas, diagnostico y tratamiento de la dermatofitosis en felinos (2020 - 2025)(Universidad Santiago de Cali, 2026-05-26) Valdez Cabrera , Diana Carolina; Ospina, Carlos Adrián (Director)La dermatofitosis felina es una micosis superficial que representa un reto persistente en la medicina veterinaria por su alta contagiosidad, potencial zoonótico y resistencia ambiental. Esta revisión sistemática tuvo como objetivo analizar la evidencia científica publicada entre 2020 y 2025 sobre los factores etiológicos, métodos diagnósticos, tratamientos antifúngicos y estrategias de control ambiental relacionados con esta enfermedad en gatos. Se aplicó la metodología PRISMA 2020 para seleccionar estudios relevantes en bases de datos como Scopus, Science Direct y PubMed, priorizando investigaciones en español e inglés, centradas en felinos domésticos y en refugios. Los resultados indican que, si bien técnicas tradicionales como el cultivo micológico siguen siendo un estándar en el diagnóstico, herramientas moleculares como la PCR ofrecen mayor precisión y rapidez diagnóstica. En cuanto al tratamiento, se evidenció un uso predominante de itraconazol y terbinafina, aunque con reportes crecientes de resistencia por parte de Microsporum canis. Asimismo, la falta de estandarización en los protocolos de desinfección ambiental representa una brecha crítica en el manejo preventivo. Esta revisión destaca la necesidad de enfoques integrales, diagnósticos modernos y estrategias terapéuticas adaptadas al contexto clínico actual. Los hallazgos tienen implicaciones directas para la salud pública y la medicina veterinaria en el marco del enfoque “Una Salud”.Item Impacto de la nutrición mineral en la reproducción de las hembras bovinas en Colombia: Un enfoque sistemático(Universidad Santiago de Cali, 2026-05-26) Peñaranda Sánchez, Sara; Cabrera Matajira, Carlos Emilio (Director)Mineral nutrition plays a fundamental role in the reproductive efficiency of female cattle, as macro and microminerals are involved in essential physiological processes such as ovulation, fertilization, and embryonic development. In Colombia, mineral deficiencies represent a recurrent issue, particularly in production systems where pastures exhibit low concentrations of key elements such as calcium, phosphorus, copper, zinc and selenium. The purpose of this study was to analyze, based on published scientific information, the impact of mineral nutrition on reproductive parameters in female cattle through a systematic literature review. To achieve this, specialized databases, including: Scopus, PubMed, ScienceDirect, and Scielo were consulted, selecting studies published between 2025 and 2025 in English, Spanish, and Portuguese. The findings indicate that proper mineral supplementation significantly improves conception rates, estrus expression, uterine involution, and embryonic viability. Conversely, deficiencies in minerals such as copper and selenium were associated with infertility, abortions, delayed puberty, and repeat breeding. In conclusion, mineral nutrition is established a key factor for optimizing bovine reproduction, and its proper management contributes to enhancing the sustainability and profitability of Colombian livestock production.Item Evaluación de pruebas de laboratorio accesibles y efectivas para el diagnóstico de leptospirosis en zonas rurales con limitado acceso a agua potable. Revisión sistemática(Universidad Santiago de Cali, 2026) Clavijo Cedano, Angelika Maria; Guarín Patarroyo, Camilo Ernesto (Director)This systematic review aimed to analyze the effectiveness and accessibility of laboratory tests for the diagnosis of leptospirosis in resource-limited rural communities. A search of databases such as PubMed, ScienceDirect, Web of Science, and Google Scholar identified 125 records, of which 33 met the inclusion criteria and were analyzed qualitatively. Six were systematic reviews and 27 were empirical studies, covering research in humans and animals. The findings show the predominant use of the MAT (Microscopic Agglutination Test), ELISA, PCR, and newer molecular methodologies such as qPCR, RPA, and microfluidic-based PCR, which have demonstrated high sensitivity and specificity in rural settings. However, there remains a significant reliance on MAT and ELISA due to their low cost and availability, despite their diagnostic limitations in early stages. The studies also highlight structural factors such as a lack of infrastructure, technical training, and funding as barriers to the implementation of molecular tests in rural areas. In the animal sector, research shows a correlation between the presence of Leptospira spp. in reservoirs (rodents, cattle, bats) and its incidence in humans. Overall, the evidence demonstrates significant progress in diagnostic innovation, although the need remains for technology transfer strategies and strengthening of rural health systems to improve early detection and epidemiological control of leptospirosis.Item Cambios en los patrones de alimentación de origen antropogénico en Dasyprocta punctata y su influencia en la calidad nutricional y en la dispersión de semillas, en un parque de Santiago de Cali, Colombia(Universidad Santiago de Cali, 2025) Escobar Sanchez, Heidy Vanessa; Zapata Molano, Laura Sofia; Casilimas Cabal, Jorge Alejandro (Director)Dasyprocta punctata is a mammal native to South America that mainly inhabits forests and jungles; however, due to anthropogenic intervention, this species has demonstrated a remarkable ability to adapt to semi-urban environments with vegetation. The feeding behavior of D. punctata includes the practice of burying seeds during periods of food abundance, which if not recovered, usually germinate, contributing significantly to reforestation processes and making the species a key element in maintaining ecosystem balance. In Santiago de Cali, Valle del Cauca, Colombia, D. punctata can frequently be observed in areas close to water sources, where it finds shelter and food, however, human interaction has altered its environment and diet, for this reason, the present study was carried out in a city park, where it was evident that the inhabitants of the sector usually provide food to individuals of the species. During the research period, observations were made at different times of the day in order to identify the periods of greatest activity of D. punctata, its interaction with other species and the food provided, in order to evaluate its nutritional quality. In parallel, a questionnaire was applied to people in the area with prior knowledge of the species. The results show that the food provided mainly includes Solanum tuberosum (brown potato), Solanum lycopersycum (tomato) and Daucus carota (carrot). Although there are no detailed studies on the natural diet of the species, it was determined that these foods lack the essential nutrients for D. punctata. In addition, much of the available food is in poor condition or in the process of decomposition, which could have an impact on the health and behavior of individuals of the species. This inadequate diet not only compromises their well-being, but could also interfere with the natural process of zoochory that they perform, altering the balance of the ecosystem and the region in the future.Item Evaluación de SDMA vs creatinina en la detección temprana de la Enfermedad Renal Crónica (ERC) en gatos(Universidad Santiago de Cali, 2026-05-25) Cardona Popo, Diana Marcela; Ospina, Carlos Adrian (Director)Kidney disease (KD) is a prevalent condition in geriatric cats, and early diagnosis is crucial to improving prognosis. However, the traditional biomarker for diagnosis, serum creatinine, has limitations in terms of sensitivity and specificity. This systematic review aimed to determine the effectiveness of symmetric dimethylarginine (SDMA) versus creatinine for the early detection of kidney damage in cats, analyzing studies published between 2020 and 2025. Following the PRISMA guidelines, a search was conducted in multiple databases, selecting 11 studies that met the inclusion criteria. The results consistently demonstrated that SDMA is a more sensitive and specific biomarker than creatinine for identifying KD in its early stages (IRIS I and II), rising with a 25-40% loss of renal function. In addition, SDMA is not influenced by muscle mass, making it more reliable in geriatric or cachectic cats. However, in complex clinical scenarios, such as urethral obstruction or acute kidney injury, both markers showed similar utility. It is concluded that SDMA is superior for early detection, complementing, but not completely replacing, creatinine. Its routine incorporation into feline diagnostic profiles is recommended, although further longitudinal studies are required to standardize its use and evaluate its actual clinical impact.Item Avances en el tratamiento quirúrgico para shunt portosistémico extrahepático congénito en caninos. Revisión Sistémica(Universidad Santiago de Cali, 2025) Riasco Andrade, Eyssenn Hawer; Vargas, Oscar Julián (Asesor)This study reviews recent advances in the surgical treatment of congenital extrahepatic portosystemic shunt in dogs, a vascular anomaly highly prevalent in small breeds. The objective was to identify the most effective, minimally invasive surgical techniques with better postoperative outcomes. A systematic review of scientific literature published between 2019 and 2025 was conducted using bibliometric tools such as VOSviewer. Significant innovations were identified, including the use of ameroid constrictors, cellophane bands, transvenous embolization, and laparoscopic surgery, as well as improved diagnostic imaging techniques. It is concluded that individualized technique selection, based on clinical and anatomical characteristics, optimizes surgical management and enhances the quality of life of affected dogs.Item Detección de parásitos gastrointestinales en bovinos de pastoreo en pequeñas explotaciones ganaderas del Valle del Cauca en la raza Hartón del Valle(Universidad Santiago de Cali, 2025-12-09) Alarcón Muñoz, Isabel Cristina; Vergara Amu, Natalia; Barbosa Vinasco, Hamilton Julián (Director)The presence of gastrointestinal parasites is common in cattle, affecting their health and productivity. These parasitic infections are prevalent worldwide and are caused by nematodes, cestodes, and trematodes. Various studies have been conducted worldwide to determine parasitic prevalence in cattle of different breeds. This study determined the prevalence of PGI in cattle on small farms in the Cauca Valley, specifically in the Hartón del Valle breed. A stratified random sampling study was conducted, in which fecal samples were taken from 200 cattle of different sexes and ages. The samples were processed using direct observation in fortis and the general flotation technique with zinc sulfate, where the supernatant was observed under a microscope. A general prevalence of 16% was obtained, Finca el Agrado obtained 15.3%, and Hacienda La Cabaña 16.5%.Item Determinacion de huevos de Toxocara canis en tres parques publicos de la ciudad de Cali(Universidad Santiago de Cali, 2025-12-04) Valencia Mesa, Stefania; Guarín Patarroyo, Camilo Ernesto (Director); Cabrera, Carlos Emilio (Director)Toxocariasis is a zoonosis caused by Toxocara canis, whose eggs eliminated in canine feces remain viable in the environment under favorable conditions, representing a public health risk. This study aimed to determine the presence of T. canis eggs in three public parks in the city of Cali and to evaluate their relationship with soil physicochemical variables (pH and humidity), in addition to exploring social factors associated with pet ownership. A total of 150 soil samples (50 per park) were collected through systematic sampling and processed using the zinc sulfate flotation technique. Additionally, 90 surveys were applied to park users. Statistical analyses showed an overall positivity of 41.3%, with a significant association between egg presence and more acidic soil pH (p < 0.001) and intermediate humidity levels (p = 0.003). Environmental stratashowed no significant differences (p > 0.05). Surveys revealed that 58.9% of respondents were unaware of the zoonosis, 45.6% always collected their pets' feces, and 40% perceived park cleanliness as "fair." These findings suggest that the persistence of T. canis eggs depends on environmental factors rather than on community perception, highlighting the need for strengthened educational programs, environmental management strategies, and integrated control actions within the One Health framework.Item Aplicación subcutánea del gel de “Aloe vera Barbadensis Miller” en el precierre quirúrgico de ovariohisterectomía para la aceleración de la cicatrización(Universidad Santiago de Cali, 2026-03-26) Montoya Ceballos, Hernán David; Montoya Molina, Alicia; Rodríguez Neira, Cristian Fernando (Director)The purpose of this study was to evaluate the healing effect of Aloe Vera (Barbadensis Miller) gel applied subcutaneously in the surgical closure of ovariohysterectomy in dogs. An experimental design was used with 12 dogs, divided into 3 groups: subcutaneous protocol, topical protocol, and control protocol. For 10 days, variables such as color, swelling, exudate, presence of scab, wound length, and percentage of closure were observed. These variables were analyzed using the nonparametric Kruskal-Wallis test – Wallis test. Although the individual statistical results did not show significant progress in wound healing, the variables as a whole demonstrated a significant contribution to wound healing, both in subcutaneous and topical use.
