Abstract
|
|
|
Purpose: Methicillin Resistant Staphylococcus aureus (MRSA) has become a major clinical problem and one of the major nosocomial pathogen worldwide. The aim of the study was to investigate the epidemiological characteristics of genotypes of MRSA isolated in the A-hospital ICU.
Methods: In the period between December 2007 and May 2008, MRSA was isolated from ICU patients and its surrounding environment. Polymerase Chain Reaction (PCR) was conducted for the detection of MRSA gene. The incidence of MRSA in the clinical isolates of Staphylococcus aureus was examined by using a multiplex PCR. The spa gene of Staphylococcus aureus encodes protein A and is used for typing of MRSA. We used sequence typing of the spa gene repeat region to study the epidemiology of MRSA at a hospital.
Results: Two different genotypes of MRSA were identified with 90 isolated from the patients and its surrounding environments in the ICU.
Conclusion: This study may contribute to the development of effective strategies for preventing nosocomial infections. Genotyping may have more general application for the study of MRSA epidemic outbreak in hospital and community infection.
