ABSTRACT

BACKGROUND:

Methicil in-resistant Staphylococcus aureus (MRSA) infection had been a global problem up to 1980s, and it has become a leading pathogen giving rise to nosocomial infections now.

OBJECTIVE:

To determine the molecular types and drug susceptibilities of Staphylococcus aureus prevailed in burn ward, and to provide a basis for preventing and control ing MRSA intections.

METHODS:

A total of 53 Staphylococcus aureus strains were col ected from the burn ward in the Urumqi General Hospital of Lanzhou Military Region of Chinese PLA. These MRSA strains were identified by PCR and cefoxitin disc diffusion test, and al MRSA strains were typed by spa, SCCmec and MLST typing. In the meanwhile, antibiotic susceptibilities of 17 kinds of drugs, such as oxacil in, to Staphylococcus aureus were also determined, and drug resistance of different types of Staphylococcus aureus especial y MRSA, was analyzed. RESULTS AND

CONCLUSION:

Among 53 Staphylococcus aureus strains, 43 were identified as MRSA, containing determined for amplification of meoA (n=41) and positive for cefoxitin disc diffusion test (n=2). Three SCCmec types, four spa types, and three ST types were found. The major predominant clone was ST239-MRSA-III-t030 (90.7%), with highest resistant to oxacil in and other nine antibiotics. In conclusion, the higher MRSA isolation rate from the burn ward, and ST239-MRSA-III-t030, as the predominant clone, presents with an outbreak in the burn ward and stronger resistance to many different families of antibiotics.
