Resumen

La placentitis en yeguas ocasionada por bacterias es una de las causas más importantes de abortos, en Colombia no existe evidencia escrita de su presentación. En el presente artículo se reporta el caso de una yegua Silla Francesa de 10 años de edad, que abortó a los 9 meses de gestación y fue atendida en la Clínica Veterinaria San Jorge - Escuela de Equitación Ejército Nacional en Bogotá. La paciente presentó signos de lactancia prematura y se observó engrosamiento de la placenta, además en los hallazgos histopatológicos predominan cambios vasculares (congestión, edema y fibrina) lo que indica una placentitis aguda. En la tinción de Gram de la placenta se encontraron cocobacilos gram negativos adheridos a la superficie de las células de las vellosidades corioalantóicas y entremezclados con el material proteináceo, aparentemente algunos se ubican intracelularmente; asociando estos fenómenos a un proceso infeccioso por posibles enterobacterias (E.coli o Salmonella spp).
