introduction: stenotrophomonas maltophilia is a nosocomial multi drug resistant opportunistic pathogen which causes infections in vulnerable patients with cancer, cystic fibrosis and indwelling catheters. methods: 45 clinical s. maltophilia isolates were collected from blood samples and identified by biochemical tests. susceptibility to different antibiotics including co-trimoxazole, levofloxac...

results in general 438 urine isolates were obtained. e. coli was the most frequently occurring pathogen (54.80%), followed by klebsiella pneumoniae (16.0%), coagulase negative staphylococci (11.2%), enterobacter spp. (9.6%), proteus spp. 1.4% and p. aeruginosa (1.4%). resistance rates of e. coli isolates were 85.9% to co-trimoxazole, 80.0% to penicillin, 77.0% to ampicillin, 68.0% to chloramphe...

conclusions the emergence of streptococcus pneumoniae strains with multiple resistance needs permanent monitoring of antibiotic susceptibility patterns of clinical isolates. we have found that ceftazidime is not a suitable drug for choosing the treatment of pneumococcal infections. results the study showed that three strains (6%) and six strains (12%) indicated intermediate resistance and compl...

background: resistance patterns among nosocomial bacterial pathogens in hospitals may vary widely from country to coun­try at any given point and within the same country over time. acinetobacter baumannii is one of the most important bacte­rium causes hospital acquired infections. therefore, surveillance of antibiotic resistance of a. baumannii is necessary, espe­cially in our country which the...

background bloodstream infection (bsi) is an important cause of mortality and morbidity and among the most common health-care associated infections. in this study we described the frequency of occurrence and antimicrobial susceptibility patterns of nosocomial and community-acquired bsi isolates from a teaching hospital in tehran, iran. patients and methods this cross-sectional study was conduct...

background enterococci have emerged as more virulent and multidrug-resistant in community and hospital settings. the emergence of vancomycin resistant enterococci (vre) in hospitals has posed a serious threat to public health. the widespread use of antibiotics to treat vre infections has resulted in the development of resistant forms of these organisms. conclusions among the nanoparticles, zno ...

pseudomonas aeruginosa is an important life-threatening nosocomial pathogen and plays a prominent role in serious infections in burned patients. the current study was undertaken to characterize p. aeruginosa strains isolated from burned patients in tehran, iran. the study was conducted in a major burn center in tehran, iran in 2007. a total of seventy specimens obtained from different clinical ...

background: the main objective of this study was to determine the prevalence and antimicrobial resistance profiles of the main bacteria which are responsible forurinary tract, blood stream, cerebrospinal fluid, lower respiratory tract, and wound infections in hamadan province in the west of iran. materials and methods:in this study,a total of 773 urinary tract, 273 blood stream, 13 cerebrospina...

this study investigated the antibacterial resistance among enterococci isolated in tehran hospitals. a total of 277 enterococcus faecalis, 123 enterococcus faecium and 13 isolates of other enterococcal strains were collected from 1 march 2002 to 15 april 2004 from three teaching hospitals of tehran university of medical sciences. the minimum inhibitory concentrations (mic) of tested antibiotics...

coagulase-negative staphylococci (cns) are a main cause of nosocomial infection. the main purpose of this study was to determination of frequency of cns isolates in in hospitalized patients and their susceptibility pattern to antimicrobial agents. during 11 month study, 65 cns clinical isolates were recovered from hospitalized patients in different wards of hospital. in vitro susceptibility of ...
