    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 associated with liver fluke Fasciola hepatica in cattle and sheep in three municipalities in the Colombian Northeastern Mountains
    (Elsevier, 2020-01) Pinilla-León, Juan Carlos; Florez-Muñoz, Angel Alberto; Uribe-Delgado, Nelson
    Fasciola hepatica is a parasitic trematode of worldwide distribution, which affects cattle and a large number of mammals, including man. An investigation was carried out to the Colombian Northeastern Mountain between October 2017 and February 2018 with the aim to determine the prevalence and risk factors associated with Fasciola hepatica. Thirty-four farms whose owners agreed to participate in the study were included. Overall, 103 bovines and 97 sheep were examined. A fecal and blood sample was collected from each animal, and all the samples were identified and stored in a refrigerated box to be transported to the Parasitology laboratory for analysis. Fecal samples were processed with a coprological technique, and blood by ELISA test. A written epidemiological survey was applied on all farms. The results indicate 20.5% of coprological prevalence and 41.5% of seroprevalence (SP). Evidence of the parasite was demonstrated in the three municipalities; however, statistical differences were found (P < .05), with higher seropositivity in Duitama municipality (SP = 83.3%). Regarding risk factor, pure breeds of cattle showed 2.5 (SP = 56.1, OR = 2.5) times higher of infection than crossed breed. Cattle and sheep from 12 to 24 months of age, showed 2.5 (SP = 66.7%, OR = 2.5) and 5.9 times (SP = 44.2%, OR = 5.9), respectively, increased infection risk. The presence of snails on the farms had higher odds for testing F. hepatica-positive, therefore, showed to be an important risk factor. The presence of antibodies against F. hepatica in cattle and sheep from the region under study suggests it is endemic and should be controlled by control and prevention programs in the farms.

    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.
