Bacteriological examinations were carried out on 54 female dogs with clinical symptoms of endometritis-pyometra complex. Vaginal swabs were taken from pharmacologically treated animals but vaginal and uteral swabs were taken from surginally treated animals. Bacteria were isolated from 78.1-84.4% of the case. Among isolated bacteria Escherichia coli dominated. A lower number of isolates was obtained from the uterus than from vagina and bacteria were always isolated in a monoculture. The isolated bacteria were most sensitive to gentamycin (96.6%), neomycin (93.2%) and cotrimoxazole (85.1%).
