MICHELOUD, JF et al. Aborto por Leptospira en una yegua en Salta, Argentina. FAVE, Secc. Cienc. vet. [online]. 2015, vol.14, n.1-2, pp.38-41. ISSN 2362-5589.

Leptospirosis in horses is usually asymptomatic, although there are regions where the disease is a problem. Here, a case of abortion caused by the agent in a mare is described. Full autopsy of a fetus at term was performed; samples for direct immunofluorescence (DIF), histopathology and microbiology were collected. Additionally, a serological study of the herd was conducted, as well as seroconversion in the aborted mare. The fetus evidenced hepatomegaly, splenomegaly and jaundice. Microscopically, mononuclear hepatitis with hepatocyte dissociation, acute splenitis and glomerulonephritis, were appreciated. Although the microorganism couldn't be quite properly, the disease was confirmed by the seroconversion present in the aborted mare. Another factor was the identification of the agent through the renal imprint DIF. This case demonstrates the presence of the agent mentioned locally, and evidences that the disease can represent a problem to the equestrian industry.
