An epidemiological study was carried out on 2823 cows from 34 dairy herds from Goiania in the State of Goias-Brazil during 2001 to 2002. The pregnancy rate was 47.8%. In 1473 non-pregnant cows, causes of reproductive failure problems were sought. The most prevalent uterine infection was endometritis (17.0%). Uterine disorders such as partial hypoplasia of the genital system (0.04%), macerate fetus (0.01%), adhesion of ovaries (0.04%), stillbirth (0.04%), retained placenta (0.01%), cervix inflammation (0.6%) and abortion (0.88%) also were found. Uterine swabs were collected aseptically for microbiological culture. Gram positives cocci (41.3%) and Gram negatives rods (52.6%) were found, and Staphylococcus aureus and Escherichia coli were the most prevalent pathogens. Susceptibility patterns of microorganisms suggested the use of chloramphenicol, gentamicin and neomycin for antimicrobial therapy.
