Staphylococcus aureus is one of the most frequent agents causing hospital infections. S.aureus has a great ability to adapt itself to variety of conditions and successful clones can be epidemic and even pandemic by its ability spread from one continent to another. The aims of this study were to detect spa types of 397 methicillin-resistant S.aureus (MRSA) strains isolated from 12 centers in dif...

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...

BACKGROUND We describe coagulase-negative staphylococci (CoNS) isolates collected from ducklings exhibiting tremor in South Korea over the period of 2010 to 2011. Screening of antimicrobial susceptibility and analysis of SCCmec elements of CoNS were also investigated. RESULTS Staphylococcus cohnii was the most frequent staphylococcus (9 isolates) and S. sciuri (4 isolates), S. lentus (3 isola...

Methicillin-resistant Staphylococcus aureus (MRSA) is a major nosocomial pathogen. We sought to determine the frequency of the different types of SCCmec in MRSA isolates by performing a cross-sectional study. A total of 72 S. aureus isolates were collected from Imam Khomeini and Golestan hospitals and analysed for MRSA and SCCmec typing by multiplex PCR. The pattern of antibiotic resistance amo...

pls, a gene found in type I staphylococcal cassette chromosome mec (SCCmec) regions of methicillin-resistant Staphylococcus aureus strains, was present in 12 of the 15 human clinical Staphylococcus sciuri isolates studied. Pls was expressed in the S. sciuri isolates, although at a lower level than in S. aureus. Other parts of SCCmec could also be found in the S. sciuri genome.

We report the draft genome sequences of three vancomycin-susceptible methicillin-resistant Staphylococcus aureus strains. S. aureus strain MV8 is a sequence type 8 (ST-8) staphylococcal cassette chromosome mec element type IV (SCCmec IV) derivative, while the other two strains (S. aureus MM25 and MM61) are ST-5 SCCmec II strains. MM61 is also closely related to the heterogeneous vancomycin-inte...

Sir, Studies on the molecular epidemiological characteristics of methicillin-resistant Staphylococcus aureus (MRSA) have demonstrated their genetic and geographic diversity in comparisons between the community-associated (CA) and hospitalassociated (HA) strains. In addition, it has been suggested that the CA-MRSA found in Korea is genetically different from those found in other regions of the w...

background and objectives: methicillin resistant staphylococcus aureus (mrsa) strains are divided into community associated (ca-) and hospital associated (ha-) mrsa. these strains vary in antimicrobial resistance and pathogenicity. s. aureus is one of the most common microorganisms in ocular infections. this study was aimed to determine antimicrobial resistance patterns and genetic characterist...

Methicillin-sensitive and resistant Staphylococcus aureus (MSSA and MRSA, respectively) can cause non-tuberculosis infectious spondylitis. In 43 cases of bacterial infectious spondylitis, Mycobacterium tuberculosis and S. aureus were the two major causative pathogens. MRSA caused more anterior operations and thoracic infections, while MSSA caused more posterior infections and lumbar infections....
