Canine hepatozoonosis is mainly caused by protozoa Hepatozoon canis and H. americanum that are transmitted by ingestion of infected ticks. Clinical signs may be unspecific or difficult to identify, because usually hepatozoonosis occurs associated with other disease. In Brazil, the parasite and the disease, have been identified in several states, however little is known about the clinical and anatomopathological lesions resulting from the infection. This paper reports five cases of natural infection by Hepatozoon canis in dogs from Minas Gerais State and describes for the first time in Brazil the necropsy and histopathological findings related to infection. Meronts of Hepatozoon sp., submitted to morphometric evaluation, were observed in histological sections of liver, spleen, bone marrow and kidney.

Thirteen horses and one mule from four regions of Brazil with clinical and histological diagnosis of rabies were analyzed. The clinical course lasted four days, with motor incoordination, paresis and paralysis of the legs, and decubitus. The main histopathological findings were lymphoplasmacytic meningoencephalitis and non-suppurative meningomyelitis associated with characteristic Negri bodies in 64.28% (9/14) cases, mainly in the cervical spinal cord and in Purkinje neurons of the cerebellum. In 55.55% (5/9), the animals examined were positive by for the fluorescent antibody test for rabies. All animals were positive in immunohistochemistry for rabies, whose immunolabeling were more evident in the temporal cortex, occipital cortex and cervical spinal cord. Immunohistochemistry procedure was essential to confirm all cases of rabies in the equids.
