Detection of Bacteroides fragilis Enterotoxin from Extraintestinal Clinical Isolates of B. fragilis Group Organisms

A total of 300 extraintestinal clinical isolates of Bacteroides fragilis group organisms were assayed for enterotoxin using HT29/C1 cells. Of the 179 strains of B. fragilis, 36 (20.0%) were positive for cell culture assay, a positivity which was neutralized by anti-B. fragilis enterotoxin serum; all...

Zusammenfassung:A total of 300 extraintestinal clinical isolates of Bacteroides fragilis group organisms were assayed for enterotoxin using HT29/C1 cells. Of the 179 strains of B. fragilis, 36 (20.0%) were positive for cell culture assay, a positivity which was neutralized by anti-B. fragilis enterotoxin serum; all 36 strains were confirmed to be enterotoxigenic B. fragilis (ETBF). Among B. fragilis isolated from blood, 18 (31%) of 59 strains were ETBF while 18 (15.0%) of 120 strains isolated from non-blood specimens were ETBF (p
