Bacteriologic investigations were carried out on a total of 142 fetuses aborted by cows. C. pyogenes, V. fetus, Streptococcus pyogenes animalis (Sofia), M. bovigenitalium, A. laidlawii, E. coli, and B. subtilis were isolated from 34 fetuses (24 per cent). Besides, single of these species were found in 80 per cent of the positive cases, and a mixed infection--in 20 per cent. The morphologic changes in all 34 fetuses that were positive were seen chiefly in the lungs and liver. Such lesions, however, were not instrumental in differentiating the etiologic agent.
