DEFEITOS CONGÊNITOS DIAGNOSTICADOS EM RUMINANTES NO LABORATÓRIO DE PATOLOGIA VETERINÁRIA DA UNIVERSIDADE FEDERAL DA PARAÍBA

Abstract

The fetal abnormalities occur in embryonic development stage, caused by different etiologies and in most of the cases have showed to be incompatible with life. Among the fetal malformation causes there are those caused by toxic plants, which are complex organisms that may present an unknown toxicity. This study was developed in the Histopathology Laboratory of Veterinary Medicine, at the Federal University of Paraiba, where it was accompanied cases of fetal malformation in ruminants in the period of 2014 and 2015, with the realization of macroscopic and histopathologic evaluation of these animals. It was sent for autopsy a lamb, five goats and two calves, coming from municipalities in the states of Paraíba and Rio Grande do Norte, during the drought period, corresponding to the months from November of 2014 to April of 2015, with Caesalpina pyramidalis(catingueira) ingestion historic, and not being found in the properties plants causing malformations. Necropsy and histopathological tests rule out the presence of infectious agents and was also not observed growth in microbiological culture for bacteria or fungi. Thus suggesting that the Caesalpina pyramidalis was the cause of these malformations in different regions, requiring more studies to discover its toxic principles and affected species.
