conclusions the present study showed a high prevalence of aminoglycoside-resistance genes among mrsa isolates in two cities in iran. results the results of drug susceptibility testing showed that the highest rate of resistance was against erythromycin in tehran (84.4%) and gentamicin (71.7%) in sari. all isolates were sensitive to vancomycin, and all strains harbored the meca gene. the aac (6’)...

conclusions despite the higher frequency of s. aureus nasal carriage in the interns, compared to the first year students, the difference did not reach statistical significance. therefore, attendance at medical centers cannot be considered a risk factor for increasing carriage. results out of the 200 nasal swabs obtained, the overall nasal carriage of s. aureus was 24.5% (49/200). the prevalence...

background : staphylococcus aureus strains exhibiting multiple antibiotic resistances are isolated from most communities and hospital infections. treatment of patients with these infections has been difficult. the aim of this study was to detect and extract, the egg yolk immunoglobulin y as a potential source of anti- s. aureus antibody. methods : specific igy was produced by immunizing hens wi...

methyl tertiary butyl ether (mtbe) belongs to the group of gasoline oxygenates and persistent environment contaminants, and shows potential for biodegradation in aerobic and anaerobic conditions, through application of pure microbial cultures. presented research shows that indigenous bacterial isolates 6sy and 24p, selected from oil hydrocarbons-contaminated environments, were capable of utiliz...

background and aims: the aim of present study was to investigate the molecular characteristic of staphylococcus aureus to detect mec a gene and to type sccmec in strain isolated from healthy worker at larestan hospital. material and methods: this study was carried out from the 250 nasal swab healthy worker  at larestan hospital. multiplex polymerase chain reaction for meca gene was performed in...

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: these data demonstrated that the attachment of bacteria to hydrophilic acrylic iols was more than hydrophobic pmma ones independent of the brand. according to these results the bacterial strain might have more hydrophilic properties. augmenting the biomass of biofilm by passing of time demonstrated the key role of time in biofilm formation on the iol surfaces. the differences betwe...

Here, we report the draft genome sequence of a methicillin-resistant Staphylococcus aureus (MRSA) strain with high-level mupirocin resistance (SA_ST125_MupR), isolated from a patient with recurrent bacteremia. This strain belonged to sequence type ST125, which was responsible for more than 50% of the health care-associated infections caused by MRSA in Spain.
