background methicillin-resistant staphylococcus aureus (mrsa) remains a significant public health problem and treatment challenge. objectives this study was conducted to determine the frequency, molecular types, and drug resistance of s. aureus isolated from nasal carriers in two teaching hospitals (hajar and kashani) in shahrekord, southwestern iran. methods in this cross-sectional study, 262 ...

Staphylococcus aureus infection remains an increasing problem of hospital acquired infections in burn patients, among them methicillin resistant Staphylococcus aureus poses potential cause of morbidity and mortality. Our study was carried out at the Department of Microbilogy at GMC Latur, India. From Jan 2012 to June 2013, to determine the profile of aerobic bacterial infection in burn patients...

OBJECTIVES The susceptibility of clinical isolates of Staphylococcus aureus, including methicillin-resistant S. aureus (MRSA), to host-derived cationic antimicrobial peptides was investigated. METHODS We examined the susceptibility of 190 clinical strains of methicillin-susceptible S. aureus (MSSA) and 304 strains of MRSA to two different classes of cationic antimicrobial peptides: LL-37 and ...

From 1 January to 31 December 2013, around Australia 26 institutions around Australia participated in the Australian Staphylococcal Sepsis Outcome Programme (ASSOP). The aim of ASSOP 2013 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 characteris...

Between August 1990 to November 1991, 905 of 2583 (35.4%) isolates of Staphylococcus aureus were found to be methicillin-resistant in a general hospital in Malaysia. A detailed study of 539 of these isolates showed a high prevalence of methicillin resistant Staphylococcus aureus (MRSA) in the surgical/orthopaedic wards, paediatric wards and the special care unit. The yield of MRSA was highest f...

Methicillin-resistant Staphylococcus aureus (MRSA) can be a commensal or pathogen in humans. Pathogenicity and disease are related to the acquisition of mobile genetic elements encoding virulence and antimicrobial resistance genes. Here, we report draft genome sequences for 50 clinical MRSA isolates from humans with MRSA-related disease.

OBJECTIVE The accessory gene regulator (agr) locus in Staphylococcus aureus (S. aureus) is a global regulator of quorum sensing and controls the production of virulence factors. This study was carried out to investigate the agr specific groups both in methicillin resistant and sensitive Staphylococcus aureus (MRSA and MSSA) and their relation with antibiotic resistance. METHODS A total of 90 ...

Background and Objectives: Staphylococcus aureus is an important cause of nosocomial and community-acquired infections in every region of the world. Clindamycin is one of the alternative agents used to treat S. aureus infections and accurate identification of clindamycin resistance is important to prevent therapeutic failure. Unfortunately, inducible clindamycin resistance is not detected by st...

materials and methods fifty mrsa isolates were collected from 200 clinical samples from three different educational hospitals in ahvaz, iran, and identified by biochemical tests including catalase, oxidase, tube coagulase, mannitol fermentation, and sensitivity to furazolidone, resistance to bacitracin, pyr test and voges-proskauer test. their resistance to methicillin was evaluated using the d...
