the emergence of multidrug resistant strains of escherichia coli has complicated treatment decision and may lead to treatment failures. from april to november 2001 we prospectively evaluated the prevalence of resistance to trimethoprim-sulfamethoxazole (sxt), gentamicin, cephalothin, ciprofloxacin, and nitrofurantoin in 220 escherichia coli isolates from patients with urinary tract infections i...

The susceptibility of 50 strains of Campylobacter pyloridis, isolated from human gastric biopsies, to 20 antimicrobial agents representing the different families of antibiotics was tested. The pattern of susceptibility was similar to that of the C. jejuni-C. coli group except for ampicillin, cephalothin, and rifampin. The relative resistance to cefsulodin was also noted.

Clavulanic acid reduced the MICs of amoxicillin, carbencillin , cefamandole, cefotaxime, ceftazidime, ceftizoxime, cephalothin, and penicillin G, but not of cefoxitin or moxalactam, against 77 isolates of the Bacteroides fragilis group, all rapidly beta-lactamase positive by the nitrocefin slide test. It had no effect on the susceptibilities of eight Bacteroides distasonis strains that were slo...
