Methicillin-resistant Staphylococcus aureus has emerged as a pathogen associated with community-acquired infections worldwide. We report the spectrum of community-acquired S. aureus infections and compare the patients infected with methicillin-susceptible or methicillin-resistant strains among patients aged <20 years. Overall, 90 cases of community-acquired S. aureus were detected in an 11-year...

the objective of this study was to determine the occurrence of antimicrobial resistance among staphylococcus aureus and to estimate the presence of methicillin-resistance in s. aureus (mrsa) isolates obtained by culture and polymerase chain reaction (pcr) methods. for this purposes, 100 iranian white and feta cheese samples collected from different suppliers were initially evaluated for the occ...

introduction: methicillin-resistant staphylococcus aureus (mrsa) can cause serious and life-threatening hospital- and community-acquired infections. colonized and infected patients represent the most important reservoir of mrsa in health care facilities. therefore, in this study, mrsa isolates collected from shohada hospital in tabriz were evaluated for the frequency of meca gene and their anti...

b ackground: methicillin-resistant staphylococcus aureus (mrsa) is the one of most commonly isolated organisms from clinical samples which can cause life- threatening infections. the emergence and spread of antibiotic resistance makes the treatment of these infections more complicated. in this study, we aimed to determine  the  patterns  of  antibiotic  resistance  among  mrsa  isolates  from t...

background pyogenic bacteria and especially staphylococcus aurous (s. aurous) are the most common cause of chronic osteomyelitis. not only treatment protocol of chronic osteomyelitis occasionally is amiss but also this malady responds to treatment difficultly. objectives this study investigates antibiotic resistance pattern of s. aurous isolated from iranian patients who suffer from chronic ost...

background: staphylococcus aureus has been recognized as a major human pathogen and is the major cause of nosocomial infections. gamma-toxin, leukocidin and other bi-component toxins are a family of proteins encoded by the hlg and luk-pv, respectively. panton-valentine leukocidin (pvl) is an example of these toxins and causes leukocyte destruction and tissue necrosis. the aim of this study was ...

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 ...

background protein a is the virulence factors of staphylococcus aureus rolling in its pathogenesis, and its gene is used for typing. polymerase chain reaction-restriction fragment length polymorphism (pcr-rflp) with different enzymes has been used for this action. objectives in this study, we used bsp143i enzyme for digestion of the gene, coding protein a (spa gene) in s. aureus. the bacteria w...

conclusions regarding clinical and laboratory standards institute (clsi) definition for vancomycin susceptibility (mic < 2 μg/ml), it seems that vancomycin may not be considered as the best antibiotic in order to treat heteroresistant vancomycin intermediate s. aureus (hvisa) and vancomycin sensitive s. aureus (vssa) infections, and a new breakpoint for vancomycin and alternative antibiotics sh...

Introduction / objectives We assessed the usefulness of a new automated molecular assay (GenomEra MRSA Confirm, Abacus Diagnostica Oy, Finland), which amplifies simultaneously the marker of methicillin resistance (mecA) and a Staphylococcus aureus-specific DNA segment, in detection of methicillin sensitive and resistant S. aureus (MSSA and MRSA) and other methicillin resistant staphylococci (MR...
