摘要：

Members of the Bacteroides fragilis group are indigenous to the human and animal intestinal microbiota and they are responsible for several endogenous infections. Enterotoxigenic B. fragilis (ETBF) has been associated with acute diarrhea in children and farm animals. Immunodeficient patients are snore predisposed to different opportunistic infections, including anaerobic infections. In this study, 130 stool samples were analysed from 56 immunodeficient and 74 healthy children. Enterotoxin production was detected by cytotoxicity assay on HT-29 cells and by PCR. B. fragilis sensu strictu was prevalent in both groups and ETBF species was detected from a single stool sample belonged to an immunodeficient child with AIDS. (C) 2001 Academic Press.
