BACKGROUND Methicillin resistant Staphylococcus aureus (MRSA) has been emerged as a nosocomial and community acquired pathogen worldwide. There are many challenges for laboratory detection of MRSA. The aim of this study was to compare different phenotypic methods with PCR based method as a gold standard for detection of mecA gene. METHODS A total of 220 clinical isolates of S. aureus which we...

BACKGROUND We performed surveillance cultures of the surfaces of X-ray cassettes to assess contamination with methicillin-resistant Staphylococcus aureus (MRSA). METHODS The surfaces of 37 X-ray cassettes stored in a radiology department were cultured using mannitol salt agar containing 6 µg/mL oxacillin. Suspected methicillin-resistant staphylococcal colonies were isolated and identified by ...

The incidence of infections caused by methicillin-resistant Staphylococcus aureus (MRSA) continues to increase in many countries worldwide. Rapid identification of MRSA from clinical specimens and screening of high-risk patients for MRSA colonization have been found to be cost-effective measures for limiting the spread of the organism in hospitals (1, 6). Several screening media for the enhance...

BACKGROUND Outbreaks and prevalence of Methicillin resistant Staphylococcus aureus (MRSA) Nosocomial Infection (NI) among various populations have been well reported in literature, particularly those from developed countries. There is a paucity of information on carriage of MRSA in developing nations, including the carriage by critical healthcare givers who are potential transmitters. AIM AND...

background: methicillin resistant staphylococcus aureus (mrsa) is one of the major agents for increasing number of serious hospital and community acquired infections. the aim of this study was to investigate the occurrence of the mrsa and meca gene among nosocomial and environmental specimens in kurdistan hospitals and determining the antibiotic resistance of the isolates. materials and methods...

Introduction: Methicillin-resistant Staphylococcus aureus (MRSA) is a major cause of healthcare and community associated infection worldwide. life threatening sepsis, endocarditis and osteomyelitis caused by methicillin resistant staphylococcus aureus (MRSA) have been reported from several parts of the world. Since MRSA strains are also resistant to multiple antibiotics, there is possibility of...

Methicillin-resistant Staphylococcus aureus (MRSA) are now a worldwide problem. Cystic fibrosis (CF) patients are commonly colonized and infected by MRSA. Accurate oxacillin susceptibility testing is mandatory for the adequate management of these patients. We performed a comparison of the accuracy of different tests in CF isolates, including methicillin-susceptible S. aureus and MRSA with diffe...

Biennial community-based Staphylococcus aureus antimicrobial surveillance programs have been performed by the Australian Group for Antimicrobial Resistance (AGAR) since 2000. Over this time the percentage of S. aureus identified as methicillin resistant has increased significantly from 10.3% in 2000 to 16% in 2006. This increase has occurred throughout Australia and has been due to the emergenc...

OBJECTIVES A 1 mg/L susceptibility breakpoint for ceftaroline and staphylococci is universally agreed; EUCAST counts MIC >1 mg/L as resistant whereas CLSI and FDA count 2 mg/L as intermediate and >2 mg/L as resistant. We investigated whether routine diagnostic tests reliably distinguish MICs of 1 versus 2 mg/L. METHODS Thirty-five UK laboratories collected Staphylococcus aureus isolates and p...

UNLABELLED Cefoxitin is a potent inducer of the mecA regulatory system. It is being recommended for detection of methicillin resistance in Staphylococcus aureus (MRSA) when using disk diffusion testing. The aim of our study was to evaluate the efficacy of cefoxitin disc diffusion test to characterize MRSA and compare it with oxacillin agar screening and detection of mecA gene by PCR. MATERIAL...
