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...

nosocomial infection caused by methicillin-resistant staphylococci poses a serious problem in many countries. the aim of this study was to rapidly and reliably detect methicillin-resistant-staphylococci in order to suggest appropriate therapy. the presence or absence of the methicillin-resistance gene in 115 clinical isolates of staphylococcus aureus and 50 isolates of coagulase negative staphy...

There is a growing concern about the application of molecular methods in epidemiological studies of infectious diseases. The objective of this study was to determine the genetic stability of methicillin resistance genes in Staphylococcus aureus for the evaluation of resistance strain distribution. One hundred and fifteen S. aureus isolates from patients with staphylococcal infection were collec...

conclusions since it is highly important to rapidly detect mrsa isolates, especially in nosocomial infections, phenotypic methods may certainly be useful for this purpose. resistance to methicillin in s. aureus shows a substantially increased ability in turanose metabolism. it is concluded that fermentation of turanose at 0.7% dilution could be a rapid detection method for primary screening of ...

background: the aim of this study was to compare the biofilm formation and the prevalence of biofilm-associated genes between the isolates of methicillin-resistant (mrsa) and methicillin-susceptible (mssa) staphylococcus aureus. methods: in total, 209 s. aureus isolates were collected. the antibiotic susceptibility test was conducted using nine antibiotics according to the guidelines of clinica...

materials and methods this definitive and cross-sectional study was conducted in tehran, iran. a total of 15 s. aureus isolates were collected from wound samples with sterile swabs and were identified by the conventional diagnostic tests. the antibiotic susceptibility pattern was performed according to the clinical and laboratory standards institute (clsi, 2012) protocol. the meca gene, staphyl...

We report recurrent bacteremia due to mixed infection with two clonally derived isolates of Staphylococcus aureus in a patient with Sezary syndrome. The two isolates, one gentamicin resistant and methicillin susceptible and the other gentamicin susceptible and methicillin resistant, developed by the deletion of the mecA, ant(4')Ia, and aacA-aphD genes from a common gentamicin-resistant and meth...

In an asylum seeker centre in Schleswig-Holstein, a resident was diagnosed with furuncle caused by a Panton-Valentine leukocidine (PVL)-positive community-acquired meticillin-resistant Staphylococcus aureus (CA-MRSA). As a result of active case finding, 232 of 427 persons (54% of all residents) were screened for MRSA and two further PVL-positive CA-MRSA cases were identified

This single-center, case-control study documents a relative increase in methicillin resistance among 48 cases of Staphylococcus aureus-associated postpartum mastitis during 1998-2005. Of 21 cases with methicillin resistance, 17 (81%) occurred in 2005. Twenty (95%) isolates contained the Staphylococcus cassette chromosome mec type IV gene; this suggests that the increase is due to community-acqu...
