Slime factor production and antibiotic resistance of 67 Enterococcus faecalis strains isolated from chicken arthritis were investigated in this study. Slime factor productions of enterococci were found as 59.7%. The antibiotic resistances were investigated by testing gentamycin, penicillin, streptomycin, vancomycin, danofloxacin, and enrofloxacin. The resistance rates were found as 62.68%, 76.11%, 67.16%, 13.43%, 47.76%, 43.28%, respectively. For slime factor positive enterococci, the

... resistance rates were found as follows respectively; 82.50%, 87.50%, 92.50%, 17.50%, 72.50%, and 60.00%. In conclusion; the slime factor might play a role as a colonization factor for chicken arthritis and slime factor positive enterococci were found to be more resistant to these antibiotics. The resistance rates between slime factor positive and negative enterococci against the tested antibiotics except for vancomycin were found statistically significant (p<0.05).
