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...

The Epsilometer test (E test; AB Biodisk, Solna, Sweden), a new quantitative technique for the determination of antimicrobial susceptibility, was compared to reference methods (agar dilution and broth microdilution) for the antimicrobial susceptibility testing of Helicobacter pylori. Seventy-one H. pylori strains isolated from patients with duodenal ulcers were tested against 20 antimicrobial a...

BACKGROUND Stenotrophomonas maltophilia has emerged as an important nosocomial pathogen, capable of causing a wide spectrum of infections. Treatment is difficult because it is resistant to many antimicrobial agents, thus reducing the treatment options. The aims of this study were to describe the antimicrobial susceptibility patterns and synergistic effect of selected antimicrobial combinations ...

conclusions the presence of bft gene in b. fragilis isolates wouldnot certainly result in diarrheaamong patients. there is not enough accordance between ddm and swedish e tests for antimicrobial susceptibility of b. fragilis for some antibiotics, although in other cases a good agreement was observed. background enterotoxigenic bacteroides fragilis (etbf) are one of the most important anaerobic ...
