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...

Recently, methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-resistant Staphylococcus pseudintermedius (MRSP) have been increasingly isolated from veterinarians and companion animals. With a view to preventing the spread of MRSA and MRSP, we evaluated the occurrence and molecular characteristics of each in a veterinary college. MRSA and MRSP were isolated from nasal samples from...

Background: Nasal carriage of Staphylococcus aureus and its virulence determinants are major risk factors for subsequent infections and transmission. Objectives: The current study aimed to determine the prevalence of panton-valentine leukocidin (PVL) gene, the SCCmec types, and the prevalent methicillin-resistant Staphylococcus aureus (MRSA) genotypes in strains isolated from healthcare workers...

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...

Antibiotic-resistant patterns, a mecA homologue complex, and staphylococcal cassette chromosome mec (SCCmec) were analysed in samples of ready-to-eat (RTE) street food in Taiwan. RTE food samples (270) were collected in three densely populated Taiwanese cities between June and November 2014. Among 14 strains being identified as methicillin-resistant coagulase-negative staphylococci (MRCoNS), ge...

OBJECTIVES To identify the staphylococcal cassette chromosome mec (SCCmec) types of methicillin-resistant Staphylococcus aureus (MRSA) isolated from bovine milk, and examine the genetic relatedness between MRSA from bovine milk and MRSA from human isolates. METHODS Antimicrobial susceptibility tests were performed on MRSA isolated from bovine milk. PCR and sequencing analysis were performed t...

Coagulase-negative Staphylococcus (CoNS) species is a leading cause of nosocomial infection in patients with indwelling medical devices and immunocompromised patients. This study was conducted to determine the antibiotic resistance pattern CoNS isolated from major teaching hospital Malaysia. A total 43 isolates were collected August October 2018 at Hospital Canselor Tuanku Muhriz, Kuala Lumpur,...

Despite being a clonal pathogen, Staphylococcus aureus continues to acquire virulence and antibiotic-resistant genes located on mobile genetic elements such as genomic islands, prophages, pathogenicity islands, and the staphylococcal chromosomal cassette mec (SCCmec) by horizontal gene transfer from other staphylococci. The potential virulence of a S. aureus strain is often determined by compar...

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...

The hospital epidemiology of methicillin-resistant Staphylococcus aureus (MRSA) has changed in the past few years due to the encroachment of community-associated MRSA (CA-MRSA) strains into health care settings. MRSA strains that were isolated during a 2-year period from patients of the Luzerner Kantonsspital were analyzed to elucidate their epidemiology. Moreover, extended surveillance of indi...
