Bu çalışmada infertilite problemi olan 18 adet kısrağın klitoris ve uteruslarmdan ve 4 adet aygırın corpus penis, urethra ve fossa glandis'lerinden alman örnekler bakteriyolojik olarak incelendi ve izole edilen etkenlerin antibiyotiklere duyarlılıkları belirlendi. 18 kısrağın 15'inin (%83,3) klitorisinden ve 10'unun (%55.5)uterusundan izolasyon yapıldı. Kısrakların klitorisinden Streptococcus spp., E.eoli, K, pneumoniae, Shigella spp., Citrobacter spp,, Neisseria'spp;, Diplocoecus pneumoniae, Aeromonas sp. ve S. epidermidis ; uterusundan ise E. coli, K. pneumoniae, Streptococcus spp., Pseudomonas spp., Âeromonas spp., Yersinia spp., S. aureus, Pasteurella sp. ve S. saprophiticus izole edildi. İncelenen 4 aygırdan ise S. epidermidis, E. coli ve Citrobacter sp. izole edildi. Kısrak ve aygırlardan Taylorella equigenitalis izolasyonu yapıla-madı. İzole edilen Gram pozitif bakteriler Enrofloxacine, Ceftizoxime, Gentamycine, Oxytetracycline, Ampicilline ve Penicilline'e; gram negatif bakteriler ise Enrofloxacine, Ceftizoxime, Tetracycline, Danofloxacine, Neomycine ve Amoxycilline'e duyarlı bulundu.

In this study the samples taken from clitorises and uteries of 18 infertile mares and prepuce shaft, urethra and fossa glandises of 4 stallions were examined bacteriologically and the sensitivity of isolated agents to antibiotics , was determined. Isolation were made from clitorises of 15 (%83.3-) and uteries of 10 (%55.5) of 18 mares. E. coli, Neisseriae spp., Shigella spp., K. pneumoniae, Diplococcus pneumoniae, Aeromonas sp., Streptococcus spp., S. epidermidis and Citrobacter spp. were isolated from clitorises; Pseudomonas spp., Aeromonas spp., E. coli, Streptococcus spp., Yersinia spp., S. aureus, Pasteurella sp., S. saprophiticus, Kl. pneumoniae were isolated from the uteries of the mares. S. epidermidis, E. coli and Citrobacter sp. were isolated from 4 stallions. Taylorella equigenitalis could not be isolated from the mares and stallions. It was determined that, the Gram (+) bacteria were sensitive to Enrofloxacine, Cephtizoxime, Gentamycine, Oxytetracycline, Ampicilline and Penicilline; Gram (-) bacteria were sensitive to Enrofloxacine, Ceftizoxime, Tetracycline, Danofloxacine, Neomycine and Amoxycilline.
