| Summary: | <b>Aim:</b> The aim of this study was to investigate the antibiotic
resistances of enterococci species isolated from bovine subclinical
mastitis in dairy cows.<p>
<b>Materials and Methods:</b> A total of 392 CMT positive milk
samples were collected from dairy farms in Afyonkarahisar.
Typing of enterococcus species were performed using API
20 Strep, subsequently, antibiotic sensitivities were determined
by disk diffusion method according to the National
Committee for Clinical Laboratory Standards.<p>
<b>Results:</b> A total of 43 isolated enterococci, involved in
bovine mastitis. The majority of isolates were E. faecalis
(53.4%), followed by E. faecium (18.6%). The remaining 12
(27.9%) strains could not be classified. This study observed
that the highest percentage of resistance by E. faecalis were
to tetracycline (91.3%), erythromycin (82.6%) and penicillin
(78.2%).<p>
<b>Conclusion:</b> This study showed a high prevalence of antimicrobial
resistant E. faecalis, E. faecium and other Enterococci
species isolated from CMT positive milk samples. Resistance
to antibiotics in enterococci is becoming a concern
for human and environmental health. |
