Trasplante de microbiota fecal en el tratamiento de la parvovirosis canina: Revisión sistemática
(2025-08-21) Toro Hernández, Laura Vanessa
Canine parvovirus disease is an infectious viral disease that mainly affects puppies and unvaccinated dogs, with a
high mortality rate. The causative virus, CPV-2, causes hemorrhagic gastroenteritis and generates significant
intestinal dysbiosis. In the absence of specific antiviral treatments, medical care focuses on intensive supportive
therapy. In this context, fecal microbiota transplantation (FMT) has emerged as a promising therapeutic alternative
to restore intestinal microbial balance, enhance immunity and promote recovery. The present monograph aimed to
describe the current state of knowledge on TMF and its potential application in the treatment of canine parvovirus.
For this purpose, a systematic review of scientific literature published in the last ten years was carried out,
consulting databases such as PubMed, Scopus, ScienceDirect and Google Scholar, with clearly defined inclusion
and exclusion criteria. The results showed that dogs with parvovirosis present an increase in Proteobacteria and a
decrease in Firmicutes and Bacteroidetes. TMF allowed reversing these imbalances, restoring bacterial diversity
and promoting the production of short-chain fatty acids, essential for intestinal health. Although there is no
standardized protocol, application methods include rectal, oral or gavage administration, with proper donor
selection being crucial. In conclusion, TMF showed positive preliminary results as an adjunctive therapy in canine
parvovirosis, although further studies are required to confirm its efficacy and establish clinical guidelines.
Habronema cutáneo en equinos: aspectos epidemiológicos, diagnósticos y tratamiento en el escenario colombiano. Revisión de literatura
(2025-08-04) Fuenmayor Nariño, Diana Marcella
Cutaneous habronemiasis in horses, caused by larvae of *Habronema spp. *, is a parasitic disease with great
impact on the health, performance and economy of the equine industry. This literature review aims to compile
updated information on the epidemiology, diagnosis and treatment of this parasitosis, with special emphasis on
recent studies that cover geographical, economic and control aspects of the parasite. Key sources were identified
on the global prevalence of habronemiasis, with rates between 39% and 72%, particularly in warm climates such
as Australia, the United States, and Valle del Cauca, Colombia, where a prevalence of 45% is observed. The
epidemiological aspects reviewed highlight the life cycle and the conditions that favor the transmission of the
parasite by vectors. Diagnostic methods include coproparasitoscopic tests and molecular analyses, essential for
differential diagnosis. Regarding treatment, anthelmintics such as ivermectin and moxidectin are described, as well
as vector management using repellents and environmental control. Emphasis is also placed on preventive fly
control strategies, which are essential to reduce the incidence and morbidity of this disease in horse populations
at risk. This review contributes to an updated approach to diagnostic techniques and therapies, providing tools to
improve the management of cutaneous habronemiasis in horses and reduce its impact on the industry.
Relación entre el tamaño tumoral y la edad de presentación clínica del melanoma en equinos moros en el Valle del Cauca
(2025-06-26) Madrigal Paredes, Estefanía; Gómez Álzate, Mariana
Melanoma is a type of skin tumor originating in the melanocytes of the basal layer of the
epidermis. This neoplasm affects different areas of the body of Moorish horses and usually appears after
8 years of age. In turn, it is related to the predisposition of adulthood, genetic factors and constant
exposure to UV rays. This study presents the relationship between the age of Moorish horses and the
severity of cutaneous melanoma, with the aim of better understanding the progression of this disease.
A bibliographic review was carried out on the incidence of cutaneous melanoma in Moorish
horses and a field test in 10 Moorish horses without distinction of sex, breed, or zootechnical purpose;
From that, the size of the melanoma was measured and classified according to a clinical classification
system, and it was decided that the patient's age was in the age range of 9 and 25 years. The data were
analyzed under discrete quantitative variable parameters with the hypothesis test for Spearman's rank
evaluation coefficient and the t test for independent samples. The results showed a significant positive
assessment of R:0.76 between age and size of the melanoma, being larger and more frequent in horses
over 15 years of age.
Técnicas de analgesia loco-regional y estrategias farmacológicas para la desensibilización de nervios del miembro torácico en caninos. Revisión de literatura
(2025-05-22) Osorio Díaz, Víctor Hugo; Valencia Casanova, Kevin Andrés
This study addresses the issue related to loco-regional analgesia techniques and pharmacological strategies
applied for the desensitization of thoracic limb nerves in canines. The high rate of postoperative complications and
adverse effects associated with the excessive use of systemic anesthetics have driven the search for safer and
more effective techniques. The main objective of the research was to conduct a systematic review of indexed
literature on the techniques and drugs used in these nerve blocks in canines. The methodology included searching
databases such as PubMed, Scopus, and Google Scholar, using Boolean terms related to the topic. The results
show that, in addition to lidocaine and bupivacaine, other adjuvant drugs have been used that have demonstrated
a reduction in adverse effects and a prolonged duration of analgesia. It is concluded that the implementation of
nerve blocks with ultrasound guidance improves the accuracy of the technique, significantly reducing postoperative
complications
Determinación de la prevalencia de parásitos gastrointestinales en caballos del corregimiento del hormiguero, santiago de cali
(2025-06-17) Pérez Silva, Karla Daniela; Sánchez Parra, Leidy Valeria
Objective: To determine the prevalence of gastrointestinal parasites in horses from the Hormiguero district, Santiago
de Cali, during August-October 2024. Methodology: A descriptive cross-sectional study was conducted on 60
equines distributed across 6 breeding farms, selected through stratified random sampling (10 horses per farm).
Fecal samples were collected by spontaneous defecation and processed using standard coproparasitological
techniques including direct method, flotation with saline solution, and sedimentation. Variables such as age, sex,
and farm of origin were recorded. Results: A general parasitosis prevalence of 86.67% (52/60) was found. The most
frequent parasites were Entamoeba spp. trophozoites (46.67%, 95% CI: 34.04-59.29), Eimeria spp. eggs (26.67%,
95% CI: 15.48-37.86), and Strongylus sp. eggs (21.67%, 95% CI: 11.2432.09). Fifty percent (30/60) of animals
presented multiparasitism. Horses under 5 years showed greater susceptibility, especially for Entamoeba spp.
(82.14% of cases). No significant differences were observed by sex. Conclusions: The high prevalence found
(86.67%) indicates a significant health problem in the equine population of the district. The predominance of
protozoa and high frequency of multiparasitism suggest deficiencies in sanitary management practices. Specific
parasite control programs and improvement of management conditions are required.
