The origins of renal arteries from the abdominal aorta vary according to renal topography in many species. The right renal artery originates more cranially than the left due to the cranial position of the right kidney. This report describes a case of a left triple renal artery arising from the lateral surface of the abdominal aorta in a male mongrel adult dog. During dissection, it was observed that three renal arteries supplied the left kidney with different topographies and arrangements. The right kidney was supplied by a single renal artery. Numerical variations in canine renal arteries must be considered in surgical and experimental procedures to avoid errors arising from unfamiliarity with these variations.","PeriodicalId":30673,"journal":{"name":"Revista de Medicina Veterinaria","volume":"26 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140969284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The comprehension of the metabolic parameters linked to heightened body mass, adiposity, and energy expenditure stands as an indispensable endeavor in unraveling metabolic requisites among vertebrates. In this particular investigation, a cohort of 48 zebrafish specimens was scrutinized to determine the impact of physical exercise when subjected to a hypercaloric diet. The subjects were categorized into four distinct groups, each group respectively assigned to maintenance diets (GM, n=12, and GMex, n=12) or hypercaloric diets (GH, n=12, and GHex, n=12), with or without concurrent engagement in physical exercise. Applying a one-way ANOVA, with a significance level of P ≤ 0.05, the results revealed noteworthy findings. Among the GMex group, regarding body mass, a statistically significant variance was observed during the initial week (0.30g ± 0.10). This disparity demonstrated a reduction of 30.83% in the subsequent week, 33.59% in the fourth week, and 40.01% in the sixth week. Similarly, within the GH group, the analysis of variance unveiled significant deviations in body mass (in grams) from the inception of the study (0.32g ± 0.07), in comparison to measurements from the sixth through the thirteenth weeks. The GHex group exhibited significant differences in body mass between the first week (0.27g ± 0.08) and the subsequent weeks, extending until the thirteenth week. Furthermore, discernible variations in the length (in centimeters) of the zebrafish specimens were recorded, with statistical significance observed from the ninth (3.29cm ± 0.33) to the thirteenth weeks (3.61cm ± 0.33). The implementation of a hypercaloric diet yielded an augmentation in body mass. Additionally, the combination of this dietary regimen with physical exercise further contributed to an augmentation in the length of the zebrafish specimens. Collectively, the proposed model exhibited the capability to induce discernible metabolic effects, thereby enhancing our understanding of the intricate interplay between diet, exercise, and metabolic dynamics.","PeriodicalId":30673,"journal":{"name":"Revista de Medicina Veterinaria","volume":"22 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140967684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is a growing recognition of parasites as important factors in the conservation of species, mainly those vulnerable to extinction in a changing environment. Bears are good biological models for monitoring infectious agents in wildlife, given their life cycle, broad home range, and severity of interactions with humans and their domestic animals as a result of their behavioral plasticity, intelligence, and omnivorous food habits. In the Andean region, the only bear species listed as vulnerable is the Tremarctos ornatus. To determine the sampling gap and prioritize the approach for understanding parasite diversity in bears, I performed a systematic review and metanalysis of the documented parasites of bears across the world and discussed the possibility of the parasites recorded in these other species being present in the T. ornatus in the Andean region, specifically Colombia. In 283 relevant references, 647 records were found of 189 parasites in 37 countries. Of the bears with parasites recorded, Ursus americanus had the most numerous and complete records. The tropical species H. malayanus, M. ursinus, and T. ornatus showed the smallest parasite diversity and unseen species estimate, despite being the region where the greatest diversity of parasites was expected. Of interest are around 80 parasites that have been recorded in seven non-Colombian bear species but are documented in other species in this country.","PeriodicalId":30673,"journal":{"name":"Revista de Medicina Veterinaria","volume":"41 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140971536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Likewise, age can impact the sires’ reproductive efficiency through its seminal quality, which is strongly influenced by the bull’s sexual maturity. The study aimed to assess the bull’s age effect on the X and Y chromosomes-bearing spermatozoa ratio in semen. Sixteen Brahman bulls (Bos indicus) were grouped into two age range and their reproductive capacity was assessed. Genomic DNA was extracted from a single collection of semen to quantify by qPCR (quantitative polymerase chain reaction) the PLP and SRY genes, used as sexual chromosome markers, and autosomal GAPDH as the reference gene. The values obtained were compared using the delta Ct (2-∆Ct) method and validated with the use of a commercial sample of semen sexed for the X chromosome. The SRY gene had a proportion of 43% in bulls of 4-5 years of age and 32% in the group of 9-10 years, while the proportions of the PLP gene were 57% in bulls of 4-5 years and 68% in the 9-10 years group. This deviation from the expected ratio (1:1) in bulls of nine and ten years old with a preponderance of the X chromosome content might suggest a possible influence of age in the sex chromosome proportions in the spermatozoa; however, these results were not statistically significant.","PeriodicalId":30673,"journal":{"name":"Revista de Medicina Veterinaria","volume":"53 22","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139634333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

El objetivo de este trabajo fue realizar un estudio sanitario de enfermedades infecciosas en un hato de lechería especializada del departamento de Antioquia, y analizar su posible asociación con la infección por BLV. Para ello, se tomaron 87 muestras de sangre de vacas holstein friesian, a las cuales se les realizó una ELISA indirecta para la proteína gp51 del virus. Además, se registraron los datos de presencia/ausencia para tres enfermedades (anaplasmosis, mastitits y metritis) y el signo fiebre durante el periodo comprendido entre el 2006 y el 2014. Los datos se analizaron a través de tablas de contingencia 2x2 y Odds Ratio (OR). La prevalencia serológica del BLV en el hato fue del 82,75 %, y la presentación de enfermedades entre el 2006 y el 2014 fue de 38,27 % para mastitis, 19,58 % para anaplasmosis, 15,13 % para metritis y 27 % para fiebre. De acuerdo con la magnitud de efecto para el OR, se encontró que la seroprevalencia del BLV tiene una asociación insignificante con las enfermedades; sin embargo, se registró una asociación moderada con el signo fiebre. La fiebre es un signo que está asociado a infecciones, por lo que es posible que la respuesta inmune disminuida por el BLV este correlacionada con la presentación de otras enfermedades infecciosas.","PeriodicalId":30673,"journal":{"name":"Revista de Medicina Veterinaria","volume":"265 29‐32","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139636342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

El análisis celular por citología vaginal es un método que permite identificar las etapas del ciclo estral con mayor confiabilidad. En esta investigación se empleó el método de citología vaginal para caracterizar el ciclo reproductivo de especies de murciélagos, muestreadas entre agosto de 2018 y febrero de 2020, en una zona perirubana del norte del cordillera Central. La condición reproductiva de las hembras capturadas fue determinada mediante caracteres externos y, para aquellas en condición no reproductiva, se realizó una citología vaginal en campo y el análisis posterior de placas mediante tinción de Wrigth. Se capturaron 73 individuos (38 hembras) de 13 especies de murciélagos. De 23 hembras analizadas, 56,5 % fueron encontrada en estro, 21,7 % en proestro, 17,3 % en diestro, y 4,3 % en metaestro. La citología vaginal es una metodología de bajo costo y riesgo para el seguimiento reproductivo de las poblaciones de murciélagos, que permite entender la relación entre reproducción y factores ambientales en ambientes antropizados.

Por ejemplo, puede ayudar a reducir la resistencia antimicrobiana (RAM), la cual se produce cuando los microorganismos sufren cambios al verse expuestos a antimicrobianos; y esta aumenta el riesgo de propagación de enfermedades, por lo que es considerada un problema de salud pública a nivel mundial. El diagnóstico inadecuado de las enfermedades en animales de granja es una de las principales causas de la aparición de la RAM. Por esta razón, el diagnóstico oportuno y adecuado de las enfermedades es una de las principales estrategias para su prevención. Evidencia reciente sugiere que en Colombia los productores porcinos no acceden a la infraestructura ni los servicios diagnósticos disponibles en el país. Este artículo caracteriza e identifica las principales barreras de acceso a la red de servicios diagnósticos y cuantifica su importancia. Para esto, primero se caracterizaron cualitativamente los conocimientos, las actitudes, las percepciones, los comportamientos y las prácticas asociadas con el diagnóstico de enfermedades y el uso de antibióticos en las granjas porcinas del país. Seguidamente, se realizó un análisis del lenguaje natural complementario, cuyo objetivo fue proveer evidencia cuantitativa complementaria para la definición de las barreras. Finalmente, se cuantificó la importancia de cada una de estas necesidades. El estudio identificó 11 grupos de barreras de acceso en categorías relacionadas con falta de conocimiento, aspectos económicos, accesibilidad, entre otros. Los resultados sugieren que las barreras relacionadas con la capacitación tienen la importancia más alta para los productores. Asimismo, dichas barreras pueden apoyar la formulación de políticas públicas a nivel local e interinstitucional para la adopción de los servicios diagnósticos disponibles.","PeriodicalId":30673,"journal":{"name":"Revista de Medicina Veterinaria","volume":"35 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139540426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
