Abstract Necropsies were performed on 354 fetuses from dairy and beef herds submitted from 1994 to 2000 to the diagnostic laboratories at Instituto Nacional de Tecnología Agropecuaria, Balcarce, Argentina. Samples from the fetuses were examined for pathogenic organisms and processed for microscopic examination. An aetiological diagnosis was made for 161 (45.5\%) of the fetuses. No diagnosis was made for 193 (54.5\%) fetuses. Infectious agents were isolated from 122 (34.4\%) of the fetuses, bacterial agents being involved in 80 (22.6\%) of these. The most common bacterial agents isolated from the fetuses were Brucella abortus in 28 fetuses, Campylobacter fetus in 26 cases, and Escherichia coli in 9 cases. Bovine herpesvirus and bovine viral diarrhoea virus were found in 9 and 6 cases, respectively. Neospora caninum was detected by an immunohistochemical technique in 26 cases (7.3\%). Congenital abnormalities, dystocia and mummifications were found in 8, 19 and 11 cases, respectively.
