Bacterial isolations from bovine aborted fetuses examined in Instituto Biológico of São Paulo state, Brazil, from 1985 to 1992
During 1985-1992, 544 samples of fetal organs and anexus, including stomach contents, were bacteriologicaly examined. These specimens came from dairy herds, from several states of Brazil. Pathogenic bacteria and pure culture or predominant opportunist organisms, were the basis for diagnosis of abortifacicnt individual agents. From 257 fetuses, excluding the unsuitable ones, 37,4% were associated to bacterial causes, such as: Brucella abortus (6,2%), Leptospira sp (6,2%), Staphylococcus aureus (5,4%), Campylobacter fetus (4,7%), Streptococcus Beta hemolytic (3,5%).
