Background and Aims: Based on the results, Staphylococcus aureus is one of the serious infectious agents found in community and hospitals with remarkable potential for high morbidity and mortality around the globe. The present study was carried out for molecular investigation of methicillin-resistant Staphylococcus aureus strains and Staphylococcal Chromosomal Cassette mec (SCCmec) phenotypes i...

BACKGROUND The burden of methicillin resistant Staphylococcus aureus is a major public health concern worldwide; however the overall epidemiology of multidrug resistant strains is neither coordinated nor harmonized, particularly in developing countries including Ethiopia. Therefore, the aim of this meta-analysis was to assess the burden of methicillin resistant Staphylococcos aureus and its ant...

background and objective: community-acquired methicillin-resistant staphylococcus aureus ( ca-mrsa) is increasingly reported worldwide. we aimed to determine the frequency of invasive ca-mrsa in children admitted to the pediatric wards of imam reza and ghaem hospitals of mashhad, iran. materials and methods: in this retrospective study, data regarding s. aureus isolates from pediatric patients’...

The aim of this study was to examine phenotypic and genotypic antimicrobial resistance of staphylococci from milk samples from cows with subclinical and clinical mastitis and from cows without mastitis symptoms to methicillin, tetracyclines, macrolides and lincosamides (ML). Of 207 strains, including 34 S. aureus and 173 coagulase-negative staphylococci (CNS), 11 (6.4%) CNS strains were phenoty...

background: staphylococcus aureus can cause infections with a wide spectrum of illnesses ranging from benign skin infections to bloodstream infection leading to mortality. antimicrobial resistance especially methicillin resistance in s. aureus (mrsa strains) is currently problematic. the emergence of mrsa infections has developed in both the healthcare and the community settings.  the aim of th...

Cefoxitin is increasingly recommended for detection of methicillin resistance in Staphylococcus aureus (MRSA) when using disk diffusion testing. In this study, 95 mecA-negative S. aureus isolates and a highly genetically diverse collection of mecA-positive S. aureus types (n=50) were used to investigate the influence of technical factors such as disk potency, incubation time, and temperature on...

We describe a calorimetric assay for the detection of methicillin-resistant Staphylococcus aureus (MRSA) within 5 h. Microbial heat was calculated in culture with and without cefoxitin. Among 30 genetically distinct clinical isolates, 19/20 MRSA (95%) and 10/10 methicillin-susceptible Staphylococcus aureus (100%) were correctly identified. Microcalorimetry may be useful for rapid MRSA screening.

background clindamycin is a frequently used antimicrobial therapeutic medicine used for the treatment of skin and soft tissue infections caused by staphylococcus aureus strains. resistance to this antibiotic is either constitutive or inducible. constitutive resistance to clindamycin could be detected by standard susceptibility testing methods. inducible clindamycin resistance could not be detec...

OBJECTIVES To evaluate the usefulness of cefoxitin when used as a surrogate marker for the detection of methicillin resistance. PATIENTS AND METHODS Eight hundred and seventy-one strains of Staphylococcus aureus, collected from eight tertiary referral centres serving diverse socio-economic populations, were included in the study using NCCLS disc diffusion and the agar dilution methods.
