The research was conducted on 19 stud farms in Serbia, on 80 mares used for breeding, with and without reproductive disorders. During the two years period (from 2009 to 2010) double guarded uterine swabs from 80 mares, aged between 3 and 22 years were collected. Mares belonged to the different breeds: Thoroughbred, Standardbred, Lipizzaner and mixed breeds. It was determined, that bacterial infection of genital organs was found in 24 mares in the examined population, and the bacterial species Streptococcus zooepidemicus was diagnosed in the 11 samples from cervical swabs. In the 5 samples, Escherichia coli was isolated, while Staphylococcus epidermidis and Pasteurella multocida were present in the 2 samples each, while the other causes and simultaneous isolation of two bacterial species are much less present. These species are: Bacillus spp. plus Escherichia coli; Streptococcus zooepidemicus plus Klebsiella pneumoniae and Escherichia coli plus Streptococcus zooepidemicus. In one swab we determinated Arcanobacter pyogenes. In this examination, according to available data after natural mating, we found conception level of 43,10%, which is similar with previous reports in our country.
