In 2012, the Australian Group on Antimicrobial Resistance (AGAR) conducted a community-onset period-prevalence survey of clinical Staphylococcus aureus isolated from hospital outpatients and general practice patients including nursing homes, long term care facilities and hospice patients. Day surgery and dialysis patients were excluded. Twenty-nine medical microbiology laboratories from all sta...

Objective(s):Staphylococcus aureus is a Gram-positive pathogen, well known for its resistance andversatile lifestyle. Under unfavourable conditions, it adapts biofilm mode of growth. For staphylococcal biofilm formation, production of extracellular polymeric substances (EPS) is a pre-requisite, which is regulated by ica operon-encoded enzymes. This study was designed to know the impact of ascor...

To the Editor: Methicillin-resistant Staphylococcus aureus (MRSA) is one of the most frequently isolated bacterial pathogens in nosocomial infections. MRSA strains recently have emerged that show reduced susceptibility to vancomycin, including vancomycin-resistant S aureus (VRSA), vancomycin-intermediate S aureus (VISA), and S aureus heterogeneously resistant to vancomycin (heterogeneously resi...

The study objective was to screen both methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-sensitive S. aureus (MSSA) isolates from blood cultures for reduced susceptibility to vancomycin and teicoplanin. A total of 72 MRSA and 143 MSSA isolates were screened on brain-heart infusion agar containing either 4 mg/L vancomycin or 8 mg/L teicoplanin, using an inoculum of approximately...

To the Editor: In recent years, methicillinresistant Staphylococcus aureus (MRSA) of phage type III-29 has become the MRSA strain most frequently introduced to Dutch hospitals from other European countries.1 From July 1992 to July 1993, our 800bed regional teaching hospital experienced the continual presence of an MRSA III-29 strain that colonized or infected 29 patients hospitalized on the int...

OBJECTIVES We assessed the in vitro effect of exposing various bacteria to minocycline/rifampicin-impregnated vascular catheters on the antimicrobial activity of the catheters and the antimicrobial susceptibility of tested organisms. METHODS Segments of minocycline/rifampicin-impregnated catheters were placed in agar plates inoculated with methicillin-susceptible Staphylococcus aureus (MSSA),...

objectives: staphylococcus aureus is an important cause of serious infection in both hospital and the community. methicillin-resistant s. aureus (mrsa) is associated with high morbidity and mortality rates with rapid development of resistance. there is a need for early and reliable detection of mrsa infection to direct antibiotic therapy, and more effectively control cross-infection. in this st...

Recently, systems have been developed to create total laboratory automation for clinical microbiology. These systems allow for the automation of specimen processing, specimen incubation, and imaging of bacterial growth. In this study, we used the WASPLab to validate software that discriminates and segregates positive and negative chromogenic methicillin-resistant Staphylococcus aureus (MRSA) pl...

BACKGROUND Apart from being a major cause of mortality, nosocomial infections due to Staphylococcus aureus have been imposing a burden on patients, hospitals and health care systems. The present study was designed to determine the prevalence of methicillin resistant S. aureus (MRSA) among nosocomial isolates along with their phenotypic characterization. METHODOLOGY MRSA and methicillin sensit...
