Detection of enterotoxigenic Bacteroides fragilis by PCR [PDF]

Journal of Clinical Microbiology, 1997
Strains of enterotoxigenic Bacteroides fragilis (ETBF) are associated with diarrhea in young farm animals and, at least in particular settings, in children. Enterotoxin production by ETBF is currently detected by a tissue culture assay with HT-29 cells.

Association of Enterotoxigenic Bacteroides fragilis with Bacteremia [PDF]

Clinical Infectious Diseases, 1996
Polymerase chain reaction (PCR) assay was compared with cell culture assay performed with use of HT29/C1 (human colonic epithelial) cells for identifying strains of enterotoxin-producing Bacteroides fragilis (ETBF) isolated from extraintestinal specimens.

Enumeration of enterotoxigenic Bacteroides fragilis in municipal sewage [PDF]

Applied and Environmental Microbiology, 1990
Of 237 isolates of Bacteroides fragilis from sewage influent at the Bozeman, Mont., wastewater treatment plant, 22 (9.3%) were enterotoxigenic, as indicated by the ability to elicit fluid accumulation in the lamb ileal loop test. It appears that enterotoxigenic B. fragilis is endemic in the human population at a moderately high level.

Bile salt hydrolase in non-enterotoxigenic Bacteroides potentiates colorectal cancer

Nature Communications, 2023
Non-enterotoxigenic Bacteroides fragilis (NTBF) is abundant in colorectal cancer (CRC) patients and in a high-fat diet (HFD)-induced CRC model. Here the authors show that bile salt hydrolase-expressing NTBF is enriched in CRC patients with overweight and

Distinct interactions with cellular E-cadherin of the two virulent metalloproteinases encoded by a Bacteroides fragilis pathogenicity island. [PDF]

PLoS ONE, 2014
Bacteroides fragilis causes the majority of Gram-negative anaerobic infections in the humans. The presence of a short, 6-kb, pathogenicity island in the genome is linked to enterotoxigenic B. fragilis (ETBF). The role of the enterotoxin in B.

Enterotoxigenic and non-enterotoxigenic Bacteroides fragilis from fecal microbiota of children [PDF]

Brazilian Journal of Microbiology, 2015
Enterotoxigenic Bacteroides fragilis (ETBF) is an important part of the human and animal intestinal microbiota and is commonly associated with diarrhea. ETBF strains produce an enterotoxin encoded by the bft gene located in the B. fragilis pathogenicity island (BfPAI). Non-enterotoxigenic B.

Bacteroides fragilis Enterotoxin Gene Sequences in Patients with Inflammatory Bowel Disease

Emerging Infectious Diseases, 2000
We identified enterotoxigenic Bacteroides fragilis in stool specimens of patients with inflammatory bowel disease and other gastrointestinal disorders. The organism was detected in 11 (13.2%) of 83 patients with inflammatory bowel disease. Of 57 patients

Enrichment of Bacteroides fragilis and enterotoxigenic Bacteroides fragilis in CpG island methylator phenotype-high colorectal carcinoma. [PDF]

Clin Microbiol Infect
Data support that enterotoxigenic Bacteroides fragilis (ETBF) harbouring the Bacteroides fragilis toxin (bft) gene may promote colorectal tumourigenesis through the serrated neoplasia pathway. We hypothesized that ETBF may be enriched in colorectal carcinoma subtypes with high-level CpG island methylator phenotype (CIMP-high), BRAF mutation, and high ...

Bacteroides fragilis Toxin Induces Cleavage and Proteasome Degradation of E-cadherin in Human Breast Cancer Cell Lines BT-474 and MCF7

Korean Journal of Clinical Laboratory Science, 2023
Enterotoxigenic Bacteroides fragilis (ETBF) has been reported to promote colitis and colon cancer through the secretion of B. fragilis toxin (BFT), a zinc-dependent metalloprotease. In colonic epithelial cells, BFT induces the cleavage of E-cadherin into

Enterovirulence of Enterotoxigenic Bacteroides fragilis in Gnotobiotic Pigs [PDF]

Veterinary Pathology, 1991
A porcine isolate of enterotoxigenic Bacteroides fragilis colonized the intestinal tract and caused watery, nonhemorrhagic diarrhea when given orally to 12, 1- to 2-day-old gnotobiotic pigs. Diarrhea occurred 2 to 3 days post-inoculation and continued throughout the 4 to 6 day post-inoculation period.
