Deskripsi

Resistance of methicillin resistant Staphylococcus aureus (MRSA) were based mainly on insertion of mobile genetic elements namely Staphylococcal cassette chromosome mec (SCCmec) in the chromosome of Staphylococcus aureus. SCCmec consists of recombinase genes (ccr), mec genes complex, additional resistance genes, and insertion sequences. Recombinase genes structure mediates transfer of SCCmec from one bacteria to another. Identification of SCCmec is very important to know basic genetic resistance and to predict spreading of MRSA. The aim of this research was to analyze SCCmec type and antimicrobial susceptibility patterns. The design of this study was observational analytic study by typing SCCmec and antimicrobial susceptibility testing on July– December 2007. Isolation and identification of 45 MRSA isolates was performed in the Department of Microbiology, Faculty of Medicine, University of Padjadjaran, whereas identification of mecA gene and typing of SCCmec by multiplex PCR was performed in the Department of Microbiology, Faculty of Medicine, Sriwijaya University, Palembang. The result showed that all isolates contained mecA gene. Multiplex PCR revealed that 40 MRSA isolates had SCCmec type III and 5 isolates with type IV. All SCCmec type III isolates were multiresistant and all of the type IV were not multiresistant. In conclusion, MRSA isolates with SCCmec type III was associated with multiresistant whereas type IV was not.
