Methicillin-resistant Staphylococcus aureus (MRSA), known as a nosocomial pathogen, has been isolated from community-acquired infections since the 1980s. It has been reported that there are carriers of MRSA in the community although the rate of carriers is low and the most important risk factor of community-acquired carriage is hospitalization or referral to healthcare facilities. We attempted ...

From 1 January to 31 December 2014, 27 institutions around Australia participated in the Australian Staphylococcal Sepsis Outcome Programme (ASSOP). The aim of ASSOP 2014 was to determine the proportion of Staphylococcus aureus bacteraemia (SAB) isolates in Australia that are antimicrobial resistant, with particular emphasis on susceptibility to methicillin and to characterise the molecular epi...

results of total 60 s. aureus isolates, 51 (85%) were mrsa, and of 60 cons, 7 (11.66%) were mrcons. the results showed that the mic of chlorhexidine for all 120 isolates was 1-16 μg/ml. 15 (12.5%) isolates carried qaca/b gene, 26 (21.7%) carried qacc gene, and 38 (31.7%) carried smr gene. conclusions maintenance of mrsa isolates in the attendance of low amounts of antiseptics could result in th...

We examined the ability of 206 clinical isolates of Staphylococcus aureus to lyse T cells and found differences between Agr groups. We found that the beta and delta hemolysins are involved and that methicillin-resistant S. aureus strains are less toxic than methicillin-susceptible S. aureus strains.

conclusions our results illustrated the presence of clonal groups of highly gentamicin-resistant strains of mrsa in hospitals in tehran. the php typing method provided useful information for both clonal dissemination and determining the epidemiological links of the clonal groups of the mrsa strains. materials and methods a total of 301 s. aureus isolates were collected during january to novembe...

background hospital patients who are nasal carriers of methicillin-resistant staphylococcus aureus (mrsa) are a high-risk potential threat to themselves and other hospitalized patients. the high antibiotic resistance of these isolates renders the treatment of related infections difficult. objectives the present study, for the first time investigated the prevalence of mrsa isolates in nasal carr...

objective(s)staphylococcus aureus is a prevalent pathogen worldwide. methicillin resistant s. aureus (mrsa), which is usually multi-resistant in hospitals, has been a daunting challenge for clinicians for more than half a century. the aim of this systematic review and meta-analysis is to determine the relative frequency (rf) of mrsa in different regions of iran.materials and methodssearch terms...

To examine the association of colonization by Staphylococcus aureus and general population mortality, we followed 10,598 adults for 8.5 years on average. Methicillin-susceptible S. aureus colonization was not associated with death. Methicillin-resistant S. aureus carriage predicted death in a crude analysis but not after adjustment for socioeconomic status and co-morbidities.

Objective(s) Staphylococcus aureus is a common cause of human infection, and emergence of vancomycin-resistance S. aureus  is a great concern for treatment of methicillin-resistant S. aureus,(MRSA) in recent years (MRSA). Here, we report the isolation of high-level VRSA. Materials and Methods S. aureus was isolated from foot ulcer of a diabetic woman in Tehran, Iran. Antibiotic susceptibilit...
