Abstract:

Staphylococcus aureus is an important food pathogen and it is the main food intoxication agent all over the world. Also,  S. aureus may cause a public health problem which is single or multiple antibiotic resistance against various antibiotics. In this study, thirty one S. aureus isolates which obtained from a total of 60 raw milk samples were analyzed for their antibiotic resistance properties. Antimicrobial susceptibilities of isolates were determined by disk diffusion method with tetracycline, gentamycin, erythromycin, trimethoprim-sulfamethoxazole, chloramfenicole, ciprofloxacin and clindamycin disks according to CLSI (Clinical and Laboratory Standarts Institute). Based on our results, antibiotic resistance of S. aureus isolates were detected in gentamycin, erythromycin, tetracycline, ciprofloxacin, clindamycin, trimethoprim-sulfamethoxazole and chloramfenicole as 3.33%, 6.46% , 16.12%, 6.47%, 80.64%, 6.46%, 16.13%, respectively.  Dairy farmers should be educated about antibiotic use and comply with legal waiting periods in milk productions. Also, antibiotic residues in milk should be controlled regularly by local authorities.
