ABSTRACT

History of diseases, clinical manifestations, pathologic and histopathological findings, as well as the results of complementary studies of three animals considered representatives of an outbreak of mortality in beef cattle in a ranch located in Aldama, Tamaulipas, during the first trimester of the 2008 are presented. Babesiosis and paralytic rabies were the presumptive diagnosis in two cases. Both diseases are considered enzootic in this area. Laboratory studies demonstrated that rabies was the main problem (3/3); however, in two of them (2/3) also Babesia bovis was recognized. In enzootic areas, the presence of both diseases, bovine paralytic rabies and babesiosis, occurs simultaneously making diagnosis difficult.
