BACKGROUND & OBJECTIVES The two major genotypic markers that distinguish community acquired (CA) from hospital acquired (HA) methicillin resistant Staphylococcus aureus (MRSA) isolates are the architecture of mobile genetic element (SCCmec type) and presence of panton valentine leukocidin (PVL) toxin. This study was conducted to determine the molecular characteristics of CA- and HA- MRSA and me...

BACKGROUND Methicillin-resistant Staphylococcus aureus (MRSA) poses a major threat to public health worldwide. There are relatively few studies addressing the molecular epidemiology of MRSA in the Philippines. METHODS This study characterized MRSA isolates in terms of their antimicrobial susceptibility profile, the SCCmec type, and the presence of lukF-lukS genes for Panton-Valentine leukocid...

Forty-one methicillin-resistant Staphylococcus aureus (MRSA) hospital isolates that clearly differed from the six major pandemic clones of MRSA in pulsed-field gel electrophoresis type, mecA and Tn554 polymorphism, and epidemic behavior were selected from an international strain collection for more detailed characterization. SpaA typing, multilocus sequence typing, and SCCmec (staphylococcal ca...

Objective(s): In the current research, the prevalence of Staphylococcus aureus clones and genes encoding antimicrobial resistance and toxins were examined among 120 S. aureus strains from nosocomial infections in tehran, Iran.Materials and Methods: Antimicrobial susceptibility was examined, based on disk diffusion and PCR method to identify resistance and toxin-encoding genes. Based on the poly...

Objectives: The incidence of MRSA still remains an important public health problem. This study aimed to perform in silico analysis MLST, SCCmec, spa type, evolutionary similarity, and whole-genome sequencing (WGS) based antimicrobial susceptibility testing by using genomic data strains isolated from human infections different countries. Methods: WGS 30 were obtained as etiological agents downlo...

INTRODUCTION Infections caused by multidrug-resistant bacteria are increasingly common and represent a serious problem for public health. Staphylococcus aureus is one of the major agents of infections, and methicillin-resistant S. aureus (MRSA) has spread worldwide. The aim of this study was to phenotypically and genotypically characterize 55 MRSAs isolated in the University Hospital of Londrin...

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...

Nasal carriage of Staphylococcus aureus is an important risk factor for nosocomial and community-acquired staphylococcal infections. We investigate the prevalence of community-acquired methicillin-sensitive (CA-MSSA) and -resistant (CA-MRSA), including inducible dormant (ID)-MRSA S. aureus, and genotypes of MRSA strains of nasal cultures from 1,108 university students attending Selcuk Universit...

Objective(s): The ability of bacteria to produce biofilm and adhesion makes them more resistant to antibiotics. The current study aims to evaluate the biofilm formation by Staphylococcus aureus and to determine the prevalence of adhesion genes, also their correlation with drug resistance.Materials and Methods: A total of 96 MRSA were collected from hospitals of Iran’s western provinces during 2...

OBJECTIVE Determining the prevalence of nasal carriage of S. aureus, both sensitive to methicillin and resistant to it, in preschool children and evaluating the presence of Panton-Valentine leukocidin genes in the isolates. METHODS This was a cross-sectional study in which cultures from anterior nares were obtained from healthy preschool children. Isolates were identified as S. aureus based o...
