materials and methods this definitive and cross-sectional study was conducted in tehran, iran. a total of 15 s. aureus isolates were collected from wound samples with sterile swabs and were identified by the conventional diagnostic tests. the antibiotic susceptibility pattern was performed according to the clinical and laboratory standards institute (clsi, 2012) protocol. the meca gene, staphyl...

there is a growing concern about the application of molecular methods in epidemiological studies of infectious diseases. the objective of this study was to determine the genetic stability of methicillin resistance genes in staphylococcus aureus for the evaluation of resistance strain distribution. one hundred and fifteen s. aureus isolates from patients with staphylococcal infection were collec...

conclusions methicillin resistance is a specialized concern in clinical studies, and it is mandatory to detect this mechanism by an accurate method that is updated periodically. increasing the resistance of s. aureus to multiple antibiotics underlines the need for intermittent resistance surveillance. results methicillin resistance was detected in 38% of s. aureus isolates, confirmed by the aga...

background and objective: reports on mrsa strains are increasing worldwide. the aim of this study was to find the prevalence of mrsa strains isolated from clinical specimens and to evaluate their resistance profile. additionally we compared the phenotypic and genotypic methods for detection of methicillin resistance. materials and methods: in this cross-sectional study, a total of 41 isolates o...

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’)...

Staphylococcus aureus is colonized in the human nasal cavity and would contaminate hospital and therapeutic environments. This bacterium has a genetic diversity in terms of resistance to antimicrobial agents. Therefore, the purpose of this study was identificatied of Methicillin and Vancomycin resistant genes in Staphylococcus aureus strains which has been isolated from the nasal cavity. 189 pa...

background hospital patients who are nasal carriers of methicillin-resistant staphylococcus aureus (mrsa) are a high-risk potential threat to themselves and other hospitalized patients. the high antibiotic resistance of these isolates renders the treatment of related infections difficult. objectives the present study, for the first time investigated the prevalence of mrsa isolates in nasal carr...
