Methicillin-Resistant (MRSA) Clonal Replacement in a Malaysian Teaching Hospital: Findings from an Eight-Year Interval Molecular Surveillance.

Periodical surveillance on nosocomial pathogens is important for antimicrobial stewardship and infection control. The first methicillin-resistant (MRSA) molecular surveillance in Hospital Canselor Tuanku Muhriz (HCTM), a Malaysian teaching hospital, was performed in 2009. The dominant clone was identified as an MRSA carrying SCC type III-SCC with and + toxin genes.

Molecular surveillance of methicillin-susceptible (MSSA) isolated over a one-year period from a Malaysian Teaching Hospital.

Introduction: We report the results of a molecular surveillance study carried out on methicillin-susceptible (MSSA) isolated in a one-year duration from Hospital Canselor Tuanku Muhriz (HCTM), a tertiary hospital located in Kuala Lumpur, Malaysia.

Methods: The first strain isolated from each MSSA infection in HCTM during the year 2009 was included into the study. Antimicrobial susceptibility testing and agr group typing were carried out for all strains; virulence gene (, , TSST-1 and PVL) typing results of the strains were obtained from a previous study.
