Background: Methicillin-resistant Staphylococcus aureus (MRSA) is resistant to most antibiotics and is an important pathogen of nosocomial infections. The prevalence of community (CA-MRSA) and hospital acquired methicillin-resistant S. aureus (HA-MRSA) infection is increased. In this study we investigated the frequency of MRSA colonization and its antibiotic susceptibility in students of Rafsan...

Introduction / objectives We assessed the usefulness of a new automated molecular assay (GenomEra MRSA Confirm, Abacus Diagnostica Oy, Finland), which amplifies simultaneously the marker of methicillin resistance (mecA) and a Staphylococcus aureus-specific DNA segment, in detection of methicillin sensitive and resistant S. aureus (MSSA and MRSA) and other methicillin resistant staphylococci (MR...

The Staphylococcus aureus mutant strain PVI selected in vitro for methicillin resistance overexpressed penicillin-binding protein (PBP) 4. In the wild-type parent strain the pbp4 gene was separated by 419 nucleotides from a divergently transcribed abcA locus coding for an ATP-binding cassette transporter. The mutant PVI was shown to have a deletion in the pbp4-abcA promoter region that affected...

Human infections involving microorganisms i.e. bacteria, fungi, viruses, cause serious infections in tropical and subtropical countries of the world. In recent years, a multidrug resistance microorganism is on rise due to indiscriminate use of commercial drugs (Gutmann et al., 1988; Mohanasundari et al., 2007). Staphylococcus aureus is a Gram positive cocci arranged in clusters and is ubiquitou...

background and aims: staphylococcus aureus is one of the important pathogens around the world. the present investigation was carried out to study the distribution of staphylococcal cassette chromosome mec (sccmec) types and antibiotic resistance properties in methicillin-resistant staphylococcus aureus isolated from isfahan hospitals. materials and methods: a total of 250 clinical specimens wer...

materials and methods fifty mrsa isolates were collected from 200 clinical samples from three different educational hospitals in ahvaz, iran, and identified by biochemical tests including catalase, oxidase, tube coagulase, mannitol fermentation, and sensitivity to furazolidone, resistance to bacitracin, pyr test and voges-proskauer test. their resistance to methicillin was evaluated using the d...

patients and methods two-hundred and fifty-five clinical specimens were collected from four major provinces of iran. samples were cultured and the mrsa strains were subjected to polymerase chain reaction (pcr). the patterns of antibiotic resistance were determined using the disk diffusion method. results seventy-four out of 255 (29.01%) clinical samples were positive for mrsa. of the 74 mrsa st...

The emergence of nosocomial infections caused by CoNS has led clinicians and researchers to reconsider the role methicillin-resistant (MR-CoNS) as important agents infections. This study was conducted on clinical isolates MR-CoNS obtained from inpatients in Hospital Tengku Ampuan Afzan (HTAA) International Islamic University Malaysia Medical Center (IIUM-MC) determine their antimicrobial resist...

From 1 January to 31 December 2013, around Australia 26 institutions around Australia participated in the Australian Staphylococcal Sepsis Outcome Programme (ASSOP). The aim of ASSOP 2013 was to determine the proportion of Staphylococcus aureus bacteraemia (SAB) isolates in Australia that are antimicrobial resistant, (with particular emphasis on susceptibility to methicillin) and to characteris...
