Lung lesions in bovine fetuses aborted by Brucella abortus.

Abstract:

Considering the poor facilities available for microbiological diagno-sis in some countries where Brucella abortus is a frequent cause of bovine abortion, a study was conducted to determine if isolation of B. abortus from an aborted bovine fetus could be pbkp_redicted from a detailed histological study of the formalized lung. Thirty-nine samples of B. abortus positive and 20 negative fetal samples were examined for the presence of 14 differ-ent pulmonary lesions. Differences in the frequency of observed lesions between the positive and negative groups, were determined by odds ratios and chi square statistic. The confidence of the pbkp_rediction was calculated by means of the logistic compu-ter model. The frequency of eight lung lesions was found to be significantly (p< 0.05) different between the groups; nevertheless, these lesions were not specific enough to be able to incriminate B. abortus as the cause of abortion.
