    Current status of prevalence and risk factors associated with liver fluke Fasciola hepatica in cattle raised in different altitudinal regions of Colombia
    (2020-12) Pinilla-León, Juan Carlos; Florez, Angel Alberto; Orlandoni, Giampaolo; Tobón, Julio Cesar; Ortíz, Diego
    Fasciola hepatica is a trematode parasite with a worldwide distribution that affects mammals, including humans, and is considered a major food safety and public health problem. A research was conducted in three hundred eighty-five livestock farms located in different altitudinal regions of Colombia between February 2017 and March 2018 with the aim to determine the coprological prevalence, seroprevalence (SP) and risk factors associated with liver fluke F. hepatica. A total of 5620 fecal sample were collected from cattle and processed using sedimentation technique. Additionally, 597 blood samples were collected and processed by an ELISA test. The coprological prevalence of F. hepatica in animals and herds was 6.4% and 38.4%, respectively. Regarding the prevalence by municipalities, there was statistical association (P < .05), indicating that the prevalence was higher in those municipalities above 2000 masl (meters above sea level). Regarding risk factors, cattle raised in municipalities at 2000 to 3000 masl showed about 4 (OR = 3.96 [CI95% 3.1–5]; P < .05) times higher probability for infection than those raised at lower altitude. Cattle from 2 to 3 year of age, showed almost 4 times (OR = 3.7[CI95% 2.5–5.4]; P < .05), increased infection risk. Females and dairy breeds showed almost 2 (OR = 1.9 [CI95% 1.3–2.6]; P < .05) and 10 times (OR = 10 [CI95% 7.8–12.8]; P < .05), respectively, increased infection risk. The presence of antibodies anti- F. hepatica (SP = 37.8%; [CI95% 35.8–39.7]; P < .05) in cattle of the region under study is confirmed, which suggests an endemic behavior of this parasitosis. The present study provides current information on the prevalence of F. hepatica in different altitudinal regions of Colombia, and these findings could be useful for designing new holistic control measures for the liver fluke F. hepatica infection.

    Estudio clínico-patológico del Sarcoide FibroblásticoEquino: reporte de caso clínico
    (2019) Pinilla-León, Juan Carlos; Florez, Angel Alberto
    The case is described in a 6-year-old Colombian Paso Fino equine that presents arecurrent mass of irregular, granulomatous, ulcerative and hemorrhagic appearance in theprepuce and penis region. Surgical resolution of the tumor, histopathological study andpostoperative treatment of the equine were performed. The macroscopic characteristicsand histological description of the lesions studied showed the presence of a fibroblasticSarcoid type.

    Fasciola hepatica y otras parasitosis gastrointestinales enbovinos de doble propósito del municipio Sabana deTorres, Santander, Colombia
    (2019) Pinilla-León, Juan Carlos; Uribe-Delgado, Nelson; Florez, Angel Alberto
    El propósito de esta investigación fue determinar la prevalencia de Fasciola hepaticay otras parasitosis gastrointestinales en bovinos doble propósito del municipio Sabanade Torres, departamento de Santander, Colombia. Se colectaron 196 muestras fecales y desangre en 18 fincas de doble propósito. Los animales fueron estratificados en tres gruposetarios: 0-12, 12-24 y >24 meses. Las muestras fecales se procesaron mediante las técni-cas coprológicas de McMaster y Dennis, y la presencia de anticuerpos anti-F. hepaticase determinó mediante una prueba de ELISA indirecto. Se identificaron los géneros de losparásitos según tamaño y morfología de sus huevos o de las larvas infectivas. La preva-lencia global de parásitos gastrointestinales fue de 36.7%, siendo los valores más altospara Eimeria sp (19.4%) y Paramphistomum sp (9.2%). La prevalencia coprológica yserológica de F. hepatica fue de 4.1 y 6.1%, respectivamente, lo que refleja que el muni-cipio Sabana de Torres es una zona hipoendémica para F. hepatica. Se encontró asocia-ción estadística (p<0.05) entre el parasitismo por Eimeria sp y el grupo etario.

    Prevalence and risk factors of gastrointestinal parasites in backyard pigs reared in the Bucaramanga Metropolitan Area, Colombia
    (2020-12) Pinilla-León, Juan Carlos; Morales, Elsa; Uribe-Delgado, Nelson; Florez, Angel Alberto
    Backyard pigs have been associated with poor sanitary conditions and the development of parasitic diseases, often causing public health and food safety problems. Therefore, the aim of this study was to determine the prevalence and risk factors for gastrointestinal parasites in backyard pigs. 279 animals were sampled from thirtytwo backyard pig farms located in the Bucaramanga, Floridablanca, Giron and Piedecuesta municipalities, from Bucaramanga Metropolitan Area, Colombia. Fecal samples were taken directly from the rectum and processed by four coprological techniques. The overall prevalence of gastrointestinal parasites was 91%, being the highest values for Balantidium coli and Eimeria sp. Regarding the prevalence by municipalities, there was no statistical association (p ≥ 0.05) indicating that the prevalence was similar in the region under study. Floridablanca municipality, free-ranging pigs, access to latrines, and consumption of spring water showed to be a risk factor for nematodes, while Giron municipality, pigs > 7 months of age and access to latrines, increased infection risk for coccidian. We concluded that there is a high prevalence of gastrointestinal parasites in backyard pigs from the Bucaramanga Metropolitan Area, and that it could be controlled by improving management practices and farm facilities.

    Trasplante de microbiota fecal en un paciente con parvovirosis canina: reporte de caso clínico
    (2021-05) Pinilla-León, Juan Carlos; Florez, Angel Alberto
    El presente estudio muestra el caso de una cachorra de cuatro meses de edad que ingresó a la consulta de la clínica veterinaria «Vet Center», Bucaramanga, Colombia, por un cuadro gastroentérico severo. La paciente mostraba signos de depresión, vómito, deshidratación y fiebre. La valoración hematológica reveló una ligera anemia, y la prueba de parvovirus canino resultó positiva. Para la estabilización y tratamiento de la paciente se colocó un catéter intravenoso para el suministro de soluciones endovenosas de Ringer lactato, antibióticos, antieméticos y vitaminas. Además, se realizó como terapia adicional un trasplante de microbiota fecal al cabo de 12 horas de hospitalización, repitiéndose a las 12 horas, dando resultados satisfactorios que se discuten en este reporte clínico.
