Epidemiological Investigation of Methicillin-Resistant Staphylococcus aureus by Arbitrarily Primed PCR

Methicillin-Resistant Staphylococcus aureus (MRSA) strains are resistant to a wide range of antibiotics and are a major cause of nosocomial infections. Accurate and rapid typing of MRSA is needed to implement effective infection control measures. Arbitrarily Primed PCR (AP-PCR) is a very useful method in rapid typing. AP-PCR is not necessary information about target DNA sequence because this is basically DNA amplification and could be useful in epidemiological typing by classified band pattern. In this study, MRSA were isolated and identified from ICU, Neu, IM and Ped environments and investigated molecular typing by AP-PCR. Ped, the MRSA pattern determines the la, IIa type, 1M is Ib type, Neu is IIa type and ICU determines the IIa, lIb types. All MRSA in this study were typeable by AP-PCR, which was easy to perform and reproduce with evidence of MRSA for purposes of nosocomial infection control.
