We undertook a controlled study of children younger than 5 years in Bangladesh to determine whether enterotoxigenic Bacteroides fragilis (ETBF) was associated with diarrhea in this population.
ETBF was isolated from 22 (6.1%) of 358 patients and 5 (1.2%) of 425 controls (P=0.0001).
In children younger than 1 year, however, low isolation rates (2 to 3%) were found in both patients and controls.
In children older than 1 year, the rates were significantly higher in children with diarrhea (16 [9%] of 177) than in controls (2 [1%] of 264;P=0.00001).
When children with mixed infections with other known diarrheal pathogens were removed, the differences in children older than 1 year were still significant (7 [4%] of 177 versus 2 [1%] of 264; P=0.033).
