a survey on species and prevalence rate of bacterial agents isolated from cockroaches in three hospitals.the presence of cockroaches has health implications, such as nosocomial infection, as the insects move freely from areas within and around hospitals that may harbor pathogenic organisms. the goals of the present study were to determine species of bacteria isolated from cockroaches found in three tehran hospitals, and to determine distribution of potential vectors by species and sex. the study is descriptive laboratory research. a total of 305 cockroaches from three species were trapped and ident ...200918973441
antimicrobial susceptibility patterns of community-acquired uropathogens in tehran, iran.antibiotic resistance of urinary tract pathogens has increased worldwide. knowledge of the antibiotic resistance patterns of uropathogens in specific geographical locations is an important factor for choosing an appropriate empirical antimicrobial treatment. the aim of this study was to provide information regarding local resistance patterns of urinary pathogens to the commonly used antibiotics in tehran, iran.201020440056
detection and pfge analysis of esbl-producing isolates of proteus species isolated from patients at tehran hospitals.the production of extended-spectrum β-lactamases (esbls), in particular tem and ctx-m type, by the strains of proteus spp. is a contributing factor to the emergence of bacterial drug resistance. the aim of this study was to screen and determine of esbls genes among strains of proteus spp. at tehran hospitals.201020885345
transmissible drug resistance in certain enteric bacilli isolated in tehran.a total of 284 isolates of gram-negative enteric bacilli associated with urinary tract infections or normal fecal flora were examined for resistance to antimicrobial agents and the presence of transmissible r factors. klebsiella pneumoniae and proteus isolates exhibited the highest frequencies of resistance to antimicrobial agents. the incidence of drug resistance among clinical isolates of escherichia coli was considerably higher than its incidence among e. coli strains isolated from healthy in ...19817021077
