Despite reports of high colonization rates of ST398 livestock-associated methicillin-resistant Staphylococcus aureus (LA-MRSA) among pigs and pig farmers, the incidence of LA-MRSA infection in the general population in Canada appears to be rare in comparison to that in some European countries. In this study, the complete genome sequence of a Canadian representative LA-MRSA isolate (08BA02176) f...

We studied the transmissibility of community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) and healthcare-associated methicillin-resistant S. aureus (HA-MRSA) strains and the association of MRSA colonization pressure and MRSA transmission in critically ill children. Importantly, we found that in hospitalized children MRSA colonization pressure above 10% increases the risk of ...

Background: Nasal carriage of Staphylococcus aureus has a key role in the epidemiology and pathogenesis of infection. In this study we aimed to investigate the occurrence of the methicillin resistant Staphylococcus aureus (MRSA )and mecA gene among healthy primary school boys in north of Iran.Material and methods: This cross-sectional study was conducted from January 2017 to July 2017 in Sari l...

background: methicillin resistant staphylococcus aureus (mrsa) nasal carriers play role in development of nosocomial infections and may increase treatment costs and mortality rate. these isolates, in addition to beta lactamase, is resistant to other drugs. carrier frequency and spectrum awareness of drug sensitivity in these isolates will be useful in choosing more effective methods of control ...

results electron microscopy showed mrsa phages’ resemblance to members of the family siphoviridae, serogroups a and f. they exhibited a latent period of 70 minutes and a relatively burst size of 2,400 plaque-forming units (pfu)/infected cell. the titer of the phages was determined to be 3 × 109 pfu/ml using the by dla technique. conclusions in this study, two phages from the family siphoviridae...

conclusions the results illustrated the diversity of antibacterial resistance and virulence gene profiles among different sccmec types of s. aureus. the increased prevalence of methicillin-resistant s. aureus isolates containing different toxin and antibiotic resistance genes is a serious threat for the hospitalized patients in the intensive care units. methods in this cross-sectional study tha...

background methicillin-resistant staphylococcus aureus (mrsa) continues to be a major cause of nosocomial infections. methicillin resistance in s. aureus is caused by the acquisition of the meca gene, located on a mobile genetic element called the staphylococcal cassette chromosome (scc). objectives the aim of this study was to evaluate the presence of the predominant sccmec type present among ...

Methicillin-resistant Staphylococcus aureus sequence type 398 (ST398 MRSA) was identified in Dutch pigs and pig farmers. ST398 methicillin-susceptible S. aureus circulates among humans at low frequency (0.2%) but was isolated in 3 human cases of bacteremia (2.1%; p = 0.026). Although its natural host is probably porcine, ST398 MRSA likely causes infections in humans.

In 928 Dallas County Jail detainees, nasal carriage of Staphylococcus aureus was found in 32.8% (26.5% methicillin-susceptible Staphylococcus aureus [MSSA] and 6.3% methicillin-resistant S. aureus [MRSA]), and hand carriage was found in 24.9% (20.7% MSSA and 4.1% MRSA). Among MRSA nasal carriers, 41% had hand MRSA carriage; 29% with hand MRSA carriage had no nasal S. aureus carriage. The preval...
