ABSTRACT

Background: Malignant catarrhal fever is an infectious pan-systemic viral disease, worldwide distribuition and highly fatal.
The disease is described in many ruminant species, manly bovine. The lesions produced by malignant catarrhal fever in catlle affect upper respiratory and digestive tracts, lymph nodes, brain, eyes, kidney and urinary bladder. Affected animals present fever, depression, ocular and nasal discharge, erosions and ulcerations in the respiratory tract, keratoconjunctivitis, lymph node enlargement, hemorrhagic enteritis, encephalitis and arteritis. Four viruses are described as agents implicated on malignant catarrhal fever, although in Brazil, only ovine herpesvirus-2 has been described. Malignant catarrhal fever occurs in several regions of Brazil, including Mato Grosso state, where it was already reported in its southern region. The aim of this study was to describe the occurrence of malignant catarrhal fever in cattle in the northern region of the state of Mato Grosso.
Case: Two affected bovine were necropsied. Tissue fragments were fixed with buffered formalin 10% and the hematoxylineosin sections were submitted to histopathology examination. Bovine DNA samples were extracted from paraffin embedded tissue fragments and submitted to nested PCR detection of ovine herpesvirus-2. The disease affected two bovine, one
