We analyzed data of Staphylococcus aureus isolated from patients attending
Thammasat University Hospital, Thailand from August 2012 to July 2015. In
total, 232/502 (46%) S. aureus isolates were methicillin-resistant S. aureus (MRSA).
There was a declining trend of proportion of MRSA infection, but the prevalence
of MRSA in the last year of study remained high (38%). All 32 MRSA-infected
outpatients had history of exposure to healthcare facilities during the previous two
months and thus were not considered as having community-associated MRSA.
In addition, all these strains were negative for pvl, suggesting that these strains
were hospital-associated MRSA. All MRSA stains were susceptible to linezolid,
teicoplanin and vancomycin, but resistance to erythromycin and clindamycin
were nearly 100%. Fifty-two percent and 87% of MRSA strains were susceptible
to tetracycline and trimethoprim-sulfamethoxazole, respectively. These results
emphasize the necessity of long-term surveillance and monitoring of antimicrobial
susceptibility pattern of MRSA.
