Abstract 6535: Association of Bacteroides fragilis and enterotoxigenic Bacteroides fragilis with specific T-cell subsets in the colorectal carcinoma microenvironment

Cancer Research
Experimental studies indicate that Bacteroides fragilis (BF), including enterotoxigenic Bacteroides fragilis (ETBF), could contribute to colorectal tumorigenesis through immune-mediated inflammation. However, the interactive effect of BF, ETBF, and

Ultrastructural Lesions of EnterotoxigenicBacteroides fragilisin Rabbits

Veterinary Pathology, 1991
In previou s studies, enterotox igenic isolates of the obligate an aerobic bacterium Bacteroides fragi lis have been found in the feces of 10 to 20% of diarrheic livestock an d hu man beings.6•7•1O•1J Isolates were considere d enterotoxigenic if viable bacteria or concen tra ted bacteria-free broth filtrat es caused acc umulation of fluid in the lamb ...

EnterotoxigenicBacteroides fragilisin Hungary

Anaerobe, 1997
Bacteroides fragilis, which constitutes about 1% of the colonic microflora in humans, is the most frequent anaerobic species involved in abscesses, soft-tissue infections and bacteraemias. Additionally, enterotoxigenic strains of B. fragilis have been demonstrated to be associated with diarrhoea in domestic animals and humans.

Meningitis due to enterotoxigenicBacteroides fragilis

European Journal of Clinical Microbiology & Infectious Diseases, 1996
An enterotoxigenic strain of Bacteroides fragilis was the sole organism isolated from the cerebrospinal fluid of a two-and-a-half-month neonate who had a medullary-colonic fistula as part of a complex congenital malformation, but no brain abscess. A rapid latex particle agglutination test for detection of bacterial antigen was positive for Haemophilus ...

Antigenic characteristics of enterotoxigenic and nonenterotoxigenic isolates of Bacteroides fragilis

American Journal of Veterinary Research, 1987
SUMMARY Fecal isolates of enterotoxigenic (44 isolates) and nonenterotoxigenic (25 isolates) Bacteroides fragilis were obtained from diarrheic calves (62 isolates), lambs (2 isolates), and pigs (5 isolates). Using a Microtiter whole-cell agglutination test and gel double-diffusion analysis, the isolates were reacted with nonabsorbed rabbit antisera ...

Strain-Specific Genetic Signatures of Enterotoxigenic Bacteroides fragilis (ETBF) Reveal bft-2 as a candidate Biomarker for Colorectal Cancer.

Anaerobe
BACKGROUND The role of specific gut microbial strains in colorectal cancer (CRC) remains incompletely understood. Enterotoxigenic Bacteroides fragilis (ETBF), particularly its toxin gene (bft) isotypes, has been linked to CRC, but strain-specific ...

Enterotoxigenic Bacteroides fragilis isolated from nondiarrheic adults.

Acta microbiologica Polonica, 1997
From 220 fecal samples of nondiarrheic adults, 29 strains of Bacteroides fragilis were isolated. Nine percent of them were enterotoxigenic Bacteroides fragilis (ETBF) strains. That is the first isolation of ETBF strains from nondiarrheic adults in Poland.

Association of enterotoxigenic Bacteroides fragilis with diarrheal disease in young pigs

American Journal of Veterinary Research, 1987
SUMMARY Enterotoxigenic Bacteroides fragilis (etbf) was isolated from intestinal contents of 10 of 45 pigs with diarrhea. Of 10 etbf-positive pigs, seven were 1 to 4 weeks of age, whereas three pigs had diarrhea after weaning (6 to 8 weeks of age). Of ten pigs infected with etbf, nine were also infected with K88-positive Escherichia coli, rotavirus ...

Isolation of enterotoxigenic Bacteroides fragilis strains in Poland.

Acta microbiologica Polonica, 1995
Fecal samples of 120 children (2 weeks to 3.5 year old) hospitalized in a pediatrical ward were investigated. In 56 of them diarrhea was observed. Out of 45 anaerobic gram-negative isolated rods, two Bacteroides fragilis strains were enterotoxigenic. Production of enterotoxin was established on the Human Colonic Epithelial Cell Line HT29/C1.
