OBJECTIVES Methicillin-resistant staphylococci (MRS) isolates from healthy and diseased cats and dogs were characterized by staphylococcal cassette chromosome mec (SCCmec), multilocus sequence typing (MLST) and cassette chromosome recombinase gene (ccrAB) sequencing. METHODS PCR-directed SCCmec typing was carried out for all MRS isolates and two Staphylococcus aureus and two Staphylococcus ep...
Ninety-six methicillin-resistant Staphylococcus aureus (MRSA) isolates from eight Korean hospitals were analyzed by multilocus sequence typing, SCCmec typing, and spa typing. The predominant genotype was ST5-MRSA-II of clonal complex 5, which was found in 36 isolates from six hospitals, but ST239-MRSA-III was also common. Overall, results showed a notable genotypic diversity of MRSA strains cir...
The aims of this study were to isolation and identification of methicillin resistant Staphylococcus aureus (MRSA) from mastitic cow milk and nasal swabs of cows and related workers, investigation presence of Panton-Valentine leucocidin (PVL) genes and molecular characteristics of these isolates. One hundred forty five mastitic milk samples were obtained from of 56 cows and nasal swabs were coll...
The prevalence of methicillin-resistant Staphylococcus aureus (MRSA) is increasing in patients with cystic fibrosis (CF). We report a molecular characterization, antimicrobial resistance, and Panton-Valentine leukocidin (PVL) toxin gene detection of MRSA strains from 28 Brazilian pediatric CF patients (1 strain per patient). A significant proportion (50%) of MRSA SCCmec IV isolates was observed...
BACKGROUND Methicillin-resistant coagulase-negative staphylococci (MR-CoNS) are opportunistic pathogens and serve as a large reservoir of staphylococcal cassette chromosome mec (SCCmec). Characterization of SCCmec in MR-CoNS can generate useful information on the mobilization and evolution of this element. METHODOLOGY/PRINCIPAL FINDINGS Non-repetitive MR-CoNS clinical isolates (n = 84; 39 S. ...
PURPOSE Methicillin-resistant Staphylococcus aureus (MRSA) strains are commonly classified as hospital-acquired (HA) or community-acquired (CA). Typical HA-MRSA isolates are characterized by multidrug resistance and the SCCmec type II cassette, while CA-MRSA isolates are generally susceptible to more drug classes, are often of SCCmec type IV, and frequently carry the Panton-Valentine leukocidin...
BACKGROUND Methicillin-resistant Staphylococcus aureus (MRSA) is a common cause of nosocomial and community-acquired infections around the world. Staphylococcal cassette chromosome mec (SCCmec) typing methods are often used to study MRSA molecular epidemiology. OBJECTIVES The current study was designed to explore the distribution profiles of different SCCmec types among methicillin-resistant ...
Staphylococcus epidermidis, especially methicillin-resistant strains, may be the source of surgical site infections and may be a reservoir of staphylococcal cassette chromosome mec (SCCmec) for S. aureus. The aim of this study was to investigate the prevalence of methicillin-resistant S. epidermidis (MRSE) on the abdominal skin of females before laparotomy and determine the molecular characteri...
Background and purpose: The aims of this study were to evaluate the antibiotic resistance of Healthcare-associated Methicillin-resistant Staphylococcus aureus (HA-MRSA) and Community associated MRSA (CA-MRSA)-resistant strains of Staphylococcus aureus strains and to investigate the frequency of different types of spa typing, SCCmec I, II, III, IV, V, and type IV, among the strains of MRSA isol...
This study compares the characteristics of Staphylococcus epidermidis (SE) and Staphylococcus haemolyticus (SH) isolates from epidemiologically unrelated infections in humans (Hu) (28 SE-Hu; 8 SH-Hu) and companion animals (CpA) (12 SE-CpA; 13 SH-CpA). All isolates underwent antimicrobial susceptibility testing, multilocus sequence typing and DNA microarray profiling to detect antimicrobial resi...
