BACKGROUND Methicillin-resistant Staphylococcus aureus has been the most commonly identified pathogen in hand infections at urban centers, but the evolving antibiotic sensitivity profiles of methicillin-resistant Staphylococcus aureus are not known. The purposes of this study are to determine if multidrug resistance in methicillin-resistant Staphylococcus aureus is emerging and to provide curre...

patients and methods two-hundred and fifty-five clinical specimens were collected from four major provinces of iran. samples were cultured and the mrsa strains were subjected to polymerase chain reaction (pcr). the patterns of antibiotic resistance were determined using the disk diffusion method. results seventy-four out of 255 (29.01%) clinical samples were positive for mrsa. of the 74 mrsa st...

introduction: methicillin-resistant staphylococcus aureus (mrsa) is responsible for an increasing number of serious hospital- and community-acquired infections. usa300 is known to be the most common cause of community-acquired infections, but recently there have been some reports on hospital-acquired infections caused by this strain. methods: totally 171 isolates of s. aureus were collected fro...

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...

Background: Methicillin Resistant Staphylococcus aureus (MRSA) is a variant of Staphylococcus aureus which is resistant to all ß-lactams. Infections due to (MRSA) strains have been detected worldwide and it makes the treatment of common infections much more difficult. Objectives: This study was carried out to determine and compare the Antibiotic susceptibility patterns in Methicillin Resistant ...

conclusions the current study results showed that silver nanoparticles produced by plantago ovata seed extract had an antibacterial effect on staphylococcus aureus which was resistant against cefixime, trimethoprim-sulfamethoxazole and penicillin. results the silver nanoparticles revealed gaussian distributions with the average diameter of 13 nm with some deviations, and results showed that the...

conclusions the present study reports on a high rate of multi-drug resistance, the predominance of the frequency of class 1 integron, and the emergence of spa type t790 among iranian staphylococcus aureus strains. the results revealed that the dissemination of multi-drug resistance among staphylococcus aureus isolates may be associated with the presence of integrons. therefore, continuous surve...

Background: Activity of norA efflux pump is one of the antibiotic resistance mechanisms in ciprofloxacin resistant Staphylococcus aureus. In this study, the effect of Artemisia ciniformis extract on reducing the expression of norA efflux pumps gene in ciprofloxacin-resistant Staphylococcus aureus isolates was studied. Materials and Methods: Ciprofloxacin resistant S. aureus isolates, were trea...

Staphylococcus aureus (including Methicillin-resistant S. aureus) and coagulase negative Staphylococcus spp (including methicillin-resistant coagulase negative) permanently or transiently colonize humans and act as sources of complicated skin and soft tissue infections, bacteraemia and infective endocarditis. They also cause chronic infection of indwelling medical devices. Treatment of these in...
