An 18-year (1990-2007) database search in the files of the Laboratory of Veterinary Pathology of the Universidade Federal de Santa Maria was carried out. In this period, 19,476 exams in domestic animals were done. Out of these exams, 6,816 (34.9%) were necropsies and 12,660 (65.1%) were performed in mailed in samples by practitioners who had necropsied the animals in their private practices. Experimental cases were excluded from this study and corresponded to 54 necropsies and 15 histopathologic exams. After the exclusion 354 (5.1%) necropsies and 163 (1.2%) histopathologic exams resulted in sheep. Out of these, 265 (74.8%) cases in the group of necropsies and 96 (59%) in the group of the histopathologic exams had conclusive diagnosis. The resulting 361 conclusive cases were grouped according to the etiology: 150 (41.6%) cases of intoxications or toxi-infections; 139 (39.3%) cases of infectious and parasitary diseases; 31 (8.6%) of metabolic and nutritional diseases; 13 (3.6%) cases of neoplasms and neoplasm-like lesions; 7 (1.9%)cases of diseases caused by physical agents; 6 (1.7%) cases of iatrogenic conditions; and 4 (1.1%) of developmental diseases. Eight cases did not fit in any of the above categories and were grouped under the denomination of other conditions . Hemonchosis and poisoning by Nierembergia veitchii were the most prevalent diseases in sheep during the 18 years of this study.
