- ÍtemConsecuencias de la Neosporosis bovina en la reproducción(Universidad Cooperativa de Colombia, Facultad de Ciencias de la Salud, Medicina Veterinaría y Zootecnia, Ibagué, 2022-09-21) Balcazar Sanabria, William De Jesus; Plazas Hernandez, Fernely AugustoBovine neosporosis is a pathology caused by the Neospora Caninum parasite and it has a worldwide distribution, generating great economic losses, because it is an important cause of bovine abortion and not only of this, but also of the birth of persistently infected animals. Because of the above mentioned, it is a disease of great connotation at the level of bovine reproduction, producing abortions from the third month of gestation with greater presentation in months 5 and 6 of the gestation period, this entails enormous consequences at reproductive level. The dog has been recognized as the definitive host, which is responsible for disseminating the sporulated oocysts to the environment through its feces, these produce the infection in animals such as cattle, sheep, horses and goats, the latter acting as intermediate hosts. On the other hand, this parasitosis is transmitted vertically, this being the most characteristic and common way in the persistence of the disease within the livestock, it is also possible the horizontal transmission in which the dog plays a vital role. The main diagnostic methods are histopathology tests, immunohistochemistry and PCR in the aborted fetus, ELISA and indirect inmonofluorescence. To date, there is no effective treatment for this pathology, therefore, prevention and control methods are established for it; on the other hand, in Colombia, the presence of the pathology has been determined in different regions of the country.
- ÍtemDiagnóstico de trichomonas sp. mediante el método de cultivo (caldo de infusión de hígado) en la producción bovina de la finca San Remo, Municipio de Arauca, Arauca – Colombia.(Universidad Cooperativa de Colombia, Facultad de Ciencias de la Salud, Medicina Veterinaría y Zootecnia, Arauca, 2019-06-12) Torres Puentes, Jon.Alexander; Niño, William Fernando; Crosby Granados, Rene AlejandroReproductive diseases are the main cause of losses in livestock production, is even more significant when talking about bovine productions in which it is sought to obtain one young per female per year to consider production profitable, within these reproductive diseases highlighted by its widespread presence and easy distribution in the herds of cattle trichomoniasis; causing problems ranging from long periods between jealousy, female anestrics, repetition of jealousy, abortions, among other conditions that are translated as important losses for the producer, during the present study was selected the San Remo farm in the municipality of Arauca, farm that has been presenting a wide range of reproductive problems, including anestrics females and abortions; for the purpose of diagnosing or ruling out the presence of trichomonas sp. At the San Remo site, a total of thirty-seven (37) Zebuine females and two (2) bulls of Simmental and white Brahmin breeds were sampled, females were swabbed while males were sampled through washes. During the pre-trial period, the different samples were transferred to the biomedical basic laboratory of the El Picure Experimental Farm of the faculty of veterinary medicine and zootechnics of the Cooperativa de Colombia University, in which sowing and incubation was carried out for its subsequent analysis, where it was determined that there is no presence of trichomonas sp in the samples carried out, which indicates that the reproductive problems in the farm are due to different reasons.
- ÍtemTécnicas diagnósticas de la Leptospirosis bovina(Universidad Cooperativa de Colombia, Facultad de Ciencias de la Salud, Medicina Veterinaría y Zootecnia, Ibagué, 2023-02-02) Calderon, Juan Manuel; Bonilla Leon, LilianLeptospirosis is a zoonotic bacterial disease with a worldwide distribution that mainly affects livestock production systems in Colombia, generating large economic losses due to its effects on animal health, causing both reproductive and productive problems. The causal agent is Leptospira interrogans with its serovars Hardjo, Pomona interrogas, Icterohaemorrhagiae, and Grippotyphosa For a final diagnosis of the infection, laboratory tests are required, within which we can find two different methods, direct and indirect, for the detection of pathogenic leptospires. With direct methods, what we detect is the bacteria or its DNA in tissues or fluids of the affected and/or infected individual, using different diagnostic techniques such as PCR, culture, immunofluorescence, among others. On the other hand, there are indirect detection methods, whose purpose is to determine the presence of circulating antibodies in the individual's blood, which indicates that the bacteria exists or existed, the reference serological test is the microscopic agglutination test or MAT, there is also the ELISA test. This document seeks to collect information regarding Leptospira, emphasizing its different specialized diagnostic methods and the main characteristic lesions of the disease.
