ABSTRACT
Causes of abortion, stillbirth, and perinatal mortality in horses were investigated in the Department of Veterinary Pathology of the Federal University of Rio Grande do Sul (SPV-UFRGS) from 2000 to 2015. In this period, 107 cases were analyzed using macroscopic, microscopic, and complementary tests. Of these, 77 were aborted fetuses, 16 were stillbirths, and 14 were perinatal deaths. Conclusive diagnosis was established in 42.8% of the fetuses analyzed, with 28.6% classified as infectious origin, 9.1% as non-infectious, and 5.1% as other. Bacterial infections, especially those related to Streptococcus spp. were the most frequently observed. In stillborn foals, diagnosis was established in 62.5% of cases, and 50% of these were related to non-infectious causes, such as dystocia and birth traumas. As for perinatal mortality, a conclusive diagnosis was reached in 78.57% of cases, and infectious causes associated with bacterial infections accounted for 64.1% of these diagnoses.
Causas de aborto, natimortalidade e mortalidade perinatal em equinos foram investigadas no Setor de Patologia Veterinária da Universidade Federal do Rio Grande do Sul (SPV-UFRGS) durante o período de 2000 a 2015. Nesse período, foram analisados 107 casos através de exames macroscópico, microscópico e exames complementares, desses 77 correspondiam a fetos abortados, 16 natimortos e 14 mortes perinatais. Diagnóstico conclusivo foi estabelecido em 42,8% dos fetos analisados e classificados como origem infecciosa em 28,6% dos casos, não infecciosa com 9,1% e outros com 5,1% dos casos. As infecções bacterianas, em especial as relacionadas a Streptococcus spp. foram as mais frequentemente observadas. Em potros natimortos, diagnostico foi estabelecido em 62,5% dos casos, e destes, 50% foram relacionados a causas não infecciosas, como distocia e traumas durante o parto. Quanto a mortalidade perinatal, em 78,57% dos casos houve um diagnostico conclusivo, e as causas infecciosas associadas a infecções bacterianas corresponderam a 64,1% desses diagnósticos.

Las enfermedades infecciosas han constituido la mayor causa de muerte a nivel mundial hasta principios del sigloXX, luego de lo cual se observó una disminución relacionada a los avances en las condiciones de vida de lapoblación, la farmacología y las mejoras del medio ambiente, entre otras causas. Las condiciones socioeconómicas son determinantes de la salud de la población y a pesar de los avances observados en los últimos años, la provincia del Chaco es una de las más pobres del país. Se realizó este trabajo con el objetivo de describir la mortalidad por causas infecciosas en la provincia durante el periodo 1999-2012...
Infectious diseases have become the leading cause of death worldwide until the early twentieth century, after it was decreasing thanks to advances in pharmacology, environment, living conditions, among others. There isevidence, that the socio-economic conditions are determinants of health of the population, given that theprovince of Chaco is one of the poorest provinces in the country (33% of NBI), encourages us to describe thesituation Mortality from infectious to help promote the execution of programs or projects to improve this area causes. Objective: To describe mortality from infectious diseases in the province during the period 1999-2012...
