ANAPLASMOSIS AND BABESIOSIS IN CATTLE: CASE REPORT

Abstract

Babesiosis and anaplasmosis are two diseases that together form part of the bovine parasitic sadness complex, transmitted mainly by the Rhipicephalus (Boophilus) microplus tick. This disease affects ruminants and, when not diagnosed and/or treated, can easily lead to death. This report aims to describe the pathological changes found in a cattle that died from bovine parasitic sadness. Macroscopically, during the necropsy of this animal, changes characteristic of bovine parasitic sadness were observed, such as hepatomegaly, biliary sludge, whitish mucous membranes, icteric hypodermis and consistent, dark bile. Microscopically, changes related to parasitic sadness were found in samples collected from the spleen, liver and kidney, respectively red pulp hyperplasia, fatty degeneration and renal nephrosis. Therefore, it is concluded that necropsy and histopathology techniques can help with the diagnosis of the disease, consequently preventing economic losses caused by the disease.
