In a farm located in area of tropical humid forest were monitored forty, crossbred cows, in order to realize the bacteriological study of the uterus and to identify the bacteria isolated in cows with normal and pathological puerperium (postpartum uterine infections), using the technique of in vivo uterine swabbing. For the samples from healthy cows (n = 13), bacterial isolation was not obtained in 31 %, while in the rest (69 %) aerobic bacterias were isolated as the Streptococus spp. and Escherichia coli. In the samples of cows with pathological puerperium (n = 27) were isolated aerobic bacterias (100 %) in all the cases, and in the most severe cases (30 %) anaerobic bacteria, especially, Fusobacteium spp. and/or Bacteroides spp., and gram positive anaerobic coccus as the Peptococcus spp. It was concluded that in cows with normal puerperium non pathogenic aerobic bacteria can be isolated but in cows with pathological puerperium (postpartum metritis) was demonstrated the importance of the bacterial associations and the pathogenicity from the anaerobic bacteria in the uterus, recommending to improve the sanitary conditions to the calving and during the puerperium. The technique of uterine swabbing was reliable, and the bacterial flora of the uterus was well represented.
