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 and objectives: biofilm formation is an important virulence factor for methicillin-resistant staphylococcus aureus (mrsa). fosfomycin is a borad-spectrum antibiotic with inhibitory effects on biofilm production and β-chloro-l-alanine (β-cla) is an amino acid analog. the aim of this study was to determine effect of the combination of fosfomycin and β-cla on biofilm production by mrsa ...
conclusions these findings illustrated the presence and persistence of clonal groups of mrsa strains, in chicken meat in isfahan, iran, that serve as reservoirs to disseminate bacteriophage encoded enterotoxin and virulence agents. results all 116 isolated mrsa strains were discriminated into seven php types consisting of seven common types (cts) and were positive for meca gene. all isolates ha...
background coagulase-negative staphylococci (cons) are opportunistic pathogens. methicillin resistance is common in cons and may play an important role as reservoir of staphylococcal cassette chromosome mec (sccmec) for staphylococcus aureus. objectives the aim of this study was to determine molecular characteristics of nasal carriage of methicillin-resistant coagulase negative staphylococci am...
conclusions silver nanoparticles have high therapeutic activity against mrsa, thus can be suggested as an alternative or adjuvant with antibiotics for mrsa treatment. further studies are required to understand the synergistic effect of ag-nps combinations and to assess the safety and efficacy of new antibiotic-ag-nps combinations. background methicillin-resistant staphylococcus aureus (mrsa) ar...
background: methicillin-resistant staphylococcus aureus (mrsa) is a major cause of nosocomial and community infections that are becoming increasingly difficult to combat, because of emerging resistance to all classes of antibiotics. moreover panton-valentine leukocidin (pvl) is an important virulence factor in s. aureus and causes white blood cell destruction, necrosis and accelerat...
conclusions our results show the presence of clonal groups of enterotoxin-producing mrsa strains in this hospital in tehran. the presence of bacteriophage encoded virulence factors and resistance to oxacillin enable bacteria to produce a broad spectrum range of diseases. results out of the 279 s. aureus isolates, 91 (32.6%) strains were confirmed as mrsa. totally, 6 enterotoxin and 2 virulence ...
conclusions as a result of the full range uv-vis scanning of the responsible band in the hptlc experiments (200-700 nm), the flavonoid was the most imaginable natural compound. results through the bioassay guided fractionation method, the greatest antibacterial activities were related to the n-hexane extract. it was also revealed that the effective anti-mrsa agent of the assessed plant was a re...
background one of the most common nasocomial bacteria is methicillin resistant staphylococcus aureus (mrsa). today, herbal extracts like zataria multiflora from the lamiaceae family are increasingly used. objectives in this study, the antibacterial effect of z. multiflora on 75 strains of was evaluated. materials and methods the strains of staphylococcus aureus were examined for isolation of st...
background methicillin-resistant staphylococcus aureus (mrsa) is considered a major cause of nosocomial and community infections. its prevalence varies from country to country, even between hospitals of a country. these bacteria often have multi-resistance and can be difficult to treat. objectives the current study evaluated the effect of hydroalcoholic extract of the stem bark of juglans regia...
