title: [Bacteria isolated from intraabdominal infection and their susceptibilities to antimicrobial agents].
abstract: Bacteria isolated from intraabdominal infections during the period from July 1982 to June 1993 were investigated with regard to their classifications according to a joint research by 9 university hospitals in Japan. The following results were obtained. 1. A total of 971 strains were isolated from 684 out of 597 patients with peritonitis, and 287 strains out of 971 were isolated from postoperative peritonitis. 2. The most predominant organism isolated from patients with acute peritonitis was Escherichia coli (28%), followed by Bacteroides fragilis group (17%), Gram-positive anaerobic cocci (16%), Enterococcus spp. (9%) and Klebsiella spp. (8%). 3. Against E. coli, cefmenoxime, cefuzonam, cefozopran, aztreonam and carumonam showed MIC50 less than 0.05 micrograms/ml. Against B. fragilis group, erthromycin, clindamycin, imipenem, lincomycin and latamoxef showed MIC50 less than 0.78 micrograms/ml. 4. The most predominant organism isolated from patients with postoperative peritonitis was Enterococcus spp. (20%) and followed by Pseudomonas spp. (14%), and Staphylococcus spp. (13%), E. coli (9%), Enterobacter spp. (8%) and Klebsiella spp. (8%). We suggest that cefazolin, cefmetazole, flomoxef, cefmenoxime, cefuzonam, and latamoxef are the first choice agents in empiric therapy for the treatment of acute peritonitis.
