Endometritis remains a major clinical problem in broodmare practice. The diagnosis of endometritis is based on the presence of inflammation, the mare’s history, physical and reproductive examination including transrectal ultrasonography and laboratory diagnostic aids. In this study, eighteen repeat breeder mares were suspected to be suffering from endometritis through their examination by ultrasonography. A total of 18 uterine swabs from these mares were evaluated and the bacterial isolates were identified. The bacterial species most frequently isolated was E. coli (9 isolates, 50%), Staphylococcus aureus (5 isolates, 27.8%) and Klebsiella pneumoniae (3 isolates, 16.7%),citrobacter freundii and Streptococci (2 isolates, 11.1%). The study also revealed that other Klebsiella oxytoca, Providencia alcalifaciens and Proteus mirabilis were found in the uterine culture but in very lower frequencies. Ciprofloxacin and enrofloxacin was the most effective antimicrobial agent inhibiting most of uterine bacterial isolates in our work.
