Enterovirulence of EnterotoxigenicBacteroides fragilisin 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.

EnterotoxigenicBacteroides fragilis: a Rogue among Symbiotes [PDF]

Clinical Microbiology Reviews, 2009
SUMMARYEnterotoxigenicBacteroides fragilis(ETBF) strains are strains ofB. fragilisthat secrete a 20-kDa heat-labile zinc-dependent metalloprotease toxin termed theB. fragilistoxin (BFT). BFT is the only recognized virulence factor specific for ETBF. ETBF strains are associated with inflammatory diarrheal disease in children older than 1 year of age and

Enterotoxigenic Bacteroides fragilis-Associated Diseases and Detection

Korean Journal of Clinical Laboratory Science, 2015
정상인에서 장내세균은 숙주의 면역이나 영양 흡수를 돕지만, 때로는 기회감염균으로서 그들을 위협하기도 한다. 그 중 절대 혐기성 세균인 Bacteroides fragilis는 분비되는 장독소(enterotoxin)인 Bacteroides fragilis toxin (BFT)의 유무에 따라 nonenterotoxigenic B. fragilis (NTBF)와 enterotoxigenic B. fragilis (ETBF)로 나뉜다. ETBF는 가축 및 사람에서 설사 질환 및 대장 질환을 유발한다 그러나 때때로 ETBF를 가지고 있으나 증상이 없는 사람도 존재한다.
