Estrategias de manejo y sostenibilidad para mitigar la podredumbre roja en la caña de azúcar (Saccharum officinarum) causada por el hongo Colletotrichum falcatum: Revisión sistemática.

Sugarcane red rot, caused by Colletotrichum falcatum Went, is an important disease because of its effects on yield, juice quality, and sugar recovery. Its development is associated with infected planting material, crop residues, pathogen survival, and environmental conditions that favor infection and dissemination. Historically, management has relied on resistant varieties, healthy planting material, and phytosanitary practices; however, pathogen variability and the breakdown of resistance have increased interest in sustainable alternatives. This systematic review aimed to identify and compare sustainable strategies for managing C. falcatum, analyze agronomic practices used to control the disease, and synthesize evidence on their effectiveness. Searches were conducted in ScienceDirect, Scopus, Web of Science, PubMed, and MDPI for studies published between 2015 and 2025 in Spanish and English, following the PRISMA selection process. A total of 183 records were identified, 57 duplicates were removed, and 29 studies were included in the qualitative synthesis after screening and eligibility assessment. Biological control agents, particularly Trichoderma, Bacillus, and Pseudomonas, were the most frequently represented strategies. Among quantitatively comparable results, mustard biofumigation achieved 100% inhibition, followed by Chaetomium globosum CGSR13 (95.32%), Pseudomonas chlororaphis SRP19 (92.56%), rhamnolipids produced by Pseudomonas aeruginosa DS9 (86.60%), and Trichoderma harzianum (85.50%). The most recurrent agricultural practices were varietal resistance, healthy planting material, sanitation, and phytosanitary surveillance. Overall, the evidence supports an integrated approach combining varietal resistance, agronomic practices, and biocontrol agents, although additional field and commercial-scale validation is required.

Efectividad en el Manejo de la Obstrucción Uretral en Felinos Machos: Comparación entre Protocolos Terapéuticos en Medicina Veterinaria: Revisión Sistemática

Urethral obstruction in male cats is a common medical emergency associated with high morbidity and significant economic implications. Traditionally, urethral catheterization has been considered the treatment of choice; however, increasing recognition of the functional component of the disease has driven interest in conservative medical management strategies. The aim of this systematic review was to compare the effectiveness of the two therapeutic approaches based on the literature published between 2020 and 2026. A systematic search was conducted in electronic databases (PubMed, Scopus, and Science direct) following PRISMA 2020 guidelines. Studies in English and Spanish that focused on male cats with urethral obstruction and evaluated medical management and/or catheterization were included. After the selection process, 10 studies with different methodological designs were analyzed. The results showed that urethral catheterization maintains high immediate success rates (85–95%), although recurrence rates may reach 29.6% and the procedure is associated with iatrogenic complications. In contrast, conservative medical management demonstrated variable response rates (48–80%), with lower invasiveness and potential usefulness in selected patients, particularly in resource-limited settings. It is concluded that no absolute superiority exists between approaches, and therapeutic decisions should be individualized. Catheterization remains the standard of care in critical cases, while conservative management represents a viable alternative in specific clinical scenarios.

Prevalencia de neoplasias mamarias en caninos del laboratorio de Patología Veterinaria “Zoopath” de la ciudad de Cali, Colombia en el 2024
(Universidad Santiago de Cali, 2026-09-17) Gomez Acevedo; Juan Diego ; Gomez Acevedo; Juan Diego
Mammary neoplasms are among the most prevalent oncological pathologies in canine species, especially in older female dogs, representing a challenge in veterinary care due to their biological characteristics and degree of malignancy. In this context, the objective of the present study was to determine the prevalence of mammary neoplasms in canines diagnosed at the Zoopath Veterinary Pathology Laboratory in Cali, Colombia, during 2024. Accordingly, a retrospective study with a quantitative approach was conducted, based on the review and analysis of the laboratory's histopathological records and databases. Likewise, the information was analyzed using descriptive statistics and correlational analysis, taking into account aspects such as breed, sex, age, reproductive status, histopathological grade, histopathological diagnosis, and malignancy. Thus, the results revealed a marked predominance of cases in females and a higher frequency of occurrence in animals between 7 and 12 years of age. Specifically, complex carcinoma was the most prevalent histopathological diagnosis, with a frequency of (27,7%), followed by complex adenoma (11,7%) and ductal carcinoma (6,2% ). Furthermore, the findings provide relevant epidemiological information for the early diagnosis, prevention, and clinical management of these pathologies, while highlighting the need to continue developing research that expands knowledge about the factors associated with their occurrence. This study concluded that mammary neoplasms occur more frequently in older female dogs, with complex carcinoma identified as the most frequent diagnosis in the studied population.

Prevalencia y control de Listeria monocytogenes en embutidos y productos carnicos listos para el consumo (RTE)
(Maria Jose Sanchez Rivera, 2026-06-24) Sanchez Rivera; Maria Jose ; Sanchez Rivera; Maria Jose
Listeria monocytogenes is a very important bacterium in food safety due to its high mortality rate and its ability to survive in industrial environments and grow at refrigeration temperatures. Within this context, sausages and ready-to-eat (RTE) meat products play an important role in food safety. These foods act as direct transmission vehicles since they are consumed without prior heat treatment that could eliminate the pathogen. This review aimed to analyze the prevalence and control strategies of L. monocytogenes in sausages and RTE meat products, emphasizing its microbiological characteristics, virulence factors, and its impact on public health, based on the review of scientific articles published between 2015 and 2025. The data analysis showed a high variability in prevalence worldwide. Values ranged from a minimum of 0.3% in environments with strict sanitary surveillance to peaks of 44.77% in situations associated with specific outbreaks, being higher in products subjected to post-process handling. According to the reviewed studies, the ability to form biofilms was identified as a key factor in the persistence of the microorganism in processing plants, promoting its resistance to disinfectants and cross-contamination. Regarding environmental conditions, it was determined that L. monocytogenes can survive and grow at refrigeration temperatures, while freezing does not guarantee its elimination, increasing the risk during storage. In addition, factors such as breaks in the cold chain and deficiencies in hygienic practices contribute to its proliferation. On the other hand, control measures showed that no single strategy is completely effective, making it necessary to implement a multiple-hurdle approach that includes physical, chemical, and biological treatments, along with the application of good manufacturing practices and environmental monitoring programs. Finally, the reviewed studies showed the relationship between the presence of the pathogen and the occurrence of listeriosis outbreaks, highlighting its impact on public health, especially in vulnerable populations. In conclusion, L. monocytogenes continues to be a challenge in the RTE food industry, therefore integrated control strategies and proper risk management are required to ensure food safety.
