BACKGROUND Coagulase-negative staphylococci (CoNS) are opportunistic pathogens. Methicillin resistance is common in CoNS and may play an important role as reservoir of staphylococcal cassette chromosome mec (SCCmec) for Staphylococcus aureus. OBJECTIVES The aim of this study was to determine molecular characteristics of nasal carriage of methicillin-resistant coagulase negative staphylococci ...
background coagulase-negative staphylococci (cons) are opportunistic pathogens. methicillin resistance is common in cons and may play an important role as reservoir of staphylococcal cassette chromosome mec (sccmec) for staphylococcus aureus. objectives the aim of this study was to determine molecular characteristics of nasal carriage of methicillin-resistant coagulase negative staphylococci am...
Background and Objectives: Colonization of Staphylococcus aureus in the nose of healthcare workers (HCWs) can be considered as the main source of nosocomial infections. The aim of this study was to investigate the frequency of S. aureus nasal carriage among HCWs in Pastor and Aflatoonian hospitals in Bam, its antibiotic resistance patterns, and determine Staphylococcal protein A (spa) typing an...
OBJECTIVES Methicillin-resistant Staphylococcus aureus (MRSA) isolates from pet animals were characterized and compared with human isolates from clonal complexes most prevalent in Central Europe. METHODS S. aureus isolates were investigated for their in vitro susceptibility to antimicrobial agents by broth microdilution. Resistance genes and the Panton-Valentine leucocidin gene lukF-lukS were...
Background This study sought to understand the epidemio-ecological dynamics of MRSA isolates associated with a South African hospital over a period spanning year 2007-8 (a previous study reported in 2009) and year 2010-11 (this study). Methods One hundred and ninety three isolates were characterised by molecular fingerprinting methods including pulsed field gel electrophoresis (PFGE), spa typ...
Between December 2009 and November 2011, we collected 57 (12.3%) Staphylococcus aureus isolates from 464 pigs and 16 (30.8%) isolates from 52 farmers in the largest farm in Dakar. Fifty-one isolates (70%) belonged to four major multilocus sequence typing clonal complexes (CCs): CC152 (26.0%), CC15 (19.2%), CC5 (13.7%), and CC97 (10.9%). The CC variability among the pigs was similar to that obse...
BACKGROUND Our aim was to determine and characterize S. aureus (SA) isolated from infections in newborns for antibiotic resistance, virulence factors, genotypes, epidemiology and antibiotic consumption. METHODS Prospective surveillance of infections was conducted. Data about antibiotic treatment were analyzed. Antimicrobial susceptibility was assessed. PCR amplification was used to detect res...
In methicillin resistant Staphylococcus aureus (MRSA), the arginine catabolic mobile element (ACME) was initially described in USA300 (t008-ST8) where it is located downstream of the staphylococcal cassette chromosome mec (SCCmec). A common health-care associated MRSA in Copenhagen, Denmark (t024-ST8) is clonally related to USA300 and is frequently PCR positive for the ACME specific arcA-gene. ...
A total of 50 clinical strains of methicillin-resistant Staphylococcus aureus (MRSA) were collected from Kobe University Hospital in 2003. Molecular typing of SCCmec was performed by multiplex polymerase chain reaction (PCR) and the presence of six genes (vraR, vraG, vraA, vraF, fruA, and fruB) associated with vancomycin (VCM) resistance was examined by simple PCR analysis. Out of 50 MRSA strai...
