ABSTRACT:Leptospirosis in cattle is recognized as a major cause of reproductive loses due to abortions, early embryonic death, and infertility. The type of Leptospira serovars that are currently circulating in Colombian herds is largely unknown due to the lack of national reports. Objective: The prevalence of antibodies specific to 13 Leptospira spp serovars was investigated in unvaccinated cows from 26 herds in San Pedro de los Milagros (Province of Antioquia) dairy region. Methods: Microscopic agglutination test was used on serum samples, following WHO recommendations. Results: A total of 112/900 (12.4%) of the animals had antibody titers of 1:100 or greater to at least one Leptospira serovar. Of those positive, 34/900 (3,8%) animals seroconverted to two or more serovars. In order of decreasing prevalence, the serovars detected were: hardjo prajitno, pomona, grippotyphosa, tarassovi, copenhageni, canicola, cellodeni and bratislava. There were 28 animals seropositive. |

Se desconocen los serovares de Leptospira que actualmente se encuentran circulando en el rebaño colombiano debido a la falta de reportes nacionales. Objetivo: se investigó la prevalencia de anticuerpos específicos para 13 serovares de Leptospira spp en vacas no vacunadas de 26 rebaños en la región lechera de San Pedro de los Milagros (Provincia de Antioquia). Métodos: La prueba de aglutinación microscópica fue empleada en muestras de suero de acuerdo a las recomendaciones de la OMS. Resultados: un total de 112/900 (12,4%) de los animales presentaron títulos de anticuerpos de 1:100 o superiores para al menos un serovar de Leptospira. Entre los positivos, el 34/900 (3,8%) de los animales presentaron seroconversión para dos o más serovares. En orden decreciente de prevalencia, los serovares detectados fueron: hardjo prajitno, pomona, grippotyphosa, tarassovi, copenhageni, canicola, cellodeni y Bratislava. En total, 28 animales fueron seropositivos al serovar hardjo. Conclusion: La leptospirosis deberia ser incluida como diagnostico diferencial en problemas reproductivos en esta región.application/pdfengUniversidad de Antioquia, Facultad de Ciencias AgrariasMedellín, Colombiahttps://creativecommons.org/licenses/by-nc-sa/2.5/co/https://creativecommons.org/licenses/by-nc-sa/4.0/Atribución-NoComercial-CompartirIgual 2.5 Colombia (CC BY-NC-SA 2.5 CO)info:eu-repo/semantics/openAccesshttp://purl.org/coar/access_right/c_abf2Cross-sectional study of 13 Leptospira serovars in cows in a Colombian dairy regionEstudio transversal de 13 serovares de Leptospira en vacas en una region lechera colombianaArtículo de investigaciónhttp://purl.org/coar/resource_type/c_2df8fbb1https://purl.org/redcol/resource_type/ARThttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionRev.
