Antimicrobial-resistant Staphylococcus aureus and MRSA prevalence among Korean families and household items

초록

One-hundred-and-seventy-nine Staphylococcus aureus strains, collected from a total of 825 resident and household item samples in Korean homes nationwide, were tested, to survey the spread of antimicrobial-resistant S. aureus including the methicillin-resistant S. aureus (MRSA) strain. Antimicrobial resistance to sulfamethoxazole-trimethoprim (0.0%), teicoplanin (0.0%), tetracycline, vancomycin (0.0%,) chloramphenicol (0.0%), ciprofloxacin (1.1%), clindamycin (1.1%), amikacin (2.2%), gentamicin (8.4%), oxacillin (17.9%), erythromycin (21.8%), ampicillin (96.6%) and penicillin (96.6%), was detected by disk diffusion method and 7.3% (13/179) of the antimicrobial-resistant isolates, were multi-drug resistant (resistant to ae<yen>3 antimicrobial classes). Nine of 32 oxacillin-resistant strains, were positive for the mecA gene and identified as MRSA, in 4 residents and 4 loofah samples, by polymerase chain reaction. These findings provide public health information and contribute to preventing circulation of antimicrobial-resistant strains in community settings including healthy homes.
