Background: The genus Clostridium includes a group of Gram-positive, anaerobic bacteria which producing endospores and produce toxins when encounter conditions favorable to their development. These toxins can be produced and absorbed in the intestinal lumen, as occurs in cases of enterotoxemia (Clostridium perfringens), or are produced in areas of tissue necrosis after bacterial infections, as seen in tetanus (C. tetani), blackleg (C. chauvoei) and bacillary hemoglobinuria (C. haemolyticum), or in infections by C. chauvoei, C. novyi and C. septicum frequently associated with cases of malignant edema. The aim of this research was relates the epidemiological and clinicopathological aspects of the clostridiosis observed in the region of infl uence of the Setor de Patologia Veterinária of Universidade Federal do Rio Grande do Sul.Materials, Methods & Results: The necropsy records were reviewed from January 1996 to December 2011 to identify the cases of clostridiosis that were diagnosed. In the period, 4.689 necropsies were performed by the (SPV-UFRGS). A total of 135 cases (2.88%) were associated with clostridiosis. The most prevalent clostridiosis included tetanus (48.15%) in horses, cattle, sheep and goats; botulism (17.04%) in cattle and enterotoxemia (22.96%) in goats. Additional diseases were blackleg (5.93%) in cattle, necrotic myositis/malignant edema in horses and sheep
