background and objectives: citrobacter freundii is an opportunistic pathogen causing nosocomial infections and resistant to various antibiotics. we aimed to determine the clonal relationship of c. freundii isolates using pulsed-field gel electrophoresis (pfge). materials and methods: fifty clinical isolates of c. freundii were collected from the main hospital in kermanshah. after antibiotic sus...
conclusions the inter- and intra-hospital dissemination of resistant clones is a matter of concern and is an indicator of the level of the improvement and surveillance of standard hygiene, particularly disinfection and hand washing before and after contact with patients. given the emergence of mbl-producing strains, surveillance has become an important procedure to control the transmission of r...
Background and Objectives: Cholerae disease caused by toxigenic V. cholerae, is a major public health problem in developing countries including Iran. Epidemiological surveillance and comparative molecular analysis of isolates have demonstrated clonal diversity among epidemic strains and a continual emergence of new clones of toxigenic V.cholerae. Material and Methods: A total of 20 V.cho...
conclusions our results illustrated the presence of clonal groups of highly gentamicin-resistant strains of mrsa in hospitals in tehran. the php typing method provided useful information for both clonal dissemination and determining the epidemiological links of the clonal groups of the mrsa strains. materials and methods a total of 301 s. aureus isolates were collected during january to novembe...

Objective(s): In the current research, the prevalence of Staphylococcus aureus clones and genes encoding antimicrobial resistance and toxins were examined among 120 S. aureus strains from nosocomial infections in tehran, Iran.Materials and Methods: Antimicrobial susceptibility was examined, based on disk diffusion and PCR method to identify resistance and toxin-encoding genes. Based on the poly...
