Bacteroides sp. strain D8, the first cholesterol-reducing bacterium isolated from human feces.
The microbial community in the human colon contains bacteria that reduce cholesterol to coprostanol, but the species responsible for this conversion are still unknown. We describe here the first isolation and characterization of a cholesterol-reducing bacterium of human intestinal origin. Strain D8 was isolated from a 10(-8) dilution of a fresh stool sample provided by a senior male volunteer w...
متن کاملRapid QPCR-based assay for fecal Bacteroides spp. as a tool for assessing fecal contamination in recreational waters.
Concentrations of fecal indicator bacteria (FIB; e.g. Escherichia coli, and Enterococcus sp.) can only be used in limited ways for determining the source of fecal contamination in recreational waters because they cannot distinguish human from non-human fecal contamination. Several Bacteroides spp. have been suggested as potential alternative indicators. We have developed a rapid, culture-indepe...
متن کاملIsolation of Bacteroides fragilis from the feces of diarrheic calves and lambs.
A selective medium was developed for the isolation of Bacteroides fragilis directly from ovine and bovine fecal samples. The medium (tryptose blood agar plus polymyxin B, triclosan (Irgasan), novobiocin, and nalidixic acid) permitted growth of B. fragilis and several other species of Bacteroides but inhibited growth of most other intestinal bacteria.
متن کاملEnumeration and isolation of cellulolytic and hemicellulolytic bacteria from human feces.
The fibrolytic microbiota of the human large intestine was examined to determine the numbers and types of cellulolytic and hemicellulolytic bacteria present. Fecal samples from each of five individuals contained bacteria capable of degrading the hydrated cellulose in spinach and in wheat straw pretreated with alkaline hydrogen peroxide (AHP-WS), whereas degradation of the relatively crystalline...
متن کاملGenome sequence and description of Bacteroides timonensis sp. nov.
Bacteroides timonensis strain AP1(T) (= CSUR P194 = DSM 26083) is the type strain of B. timonensis sp. nov. This strain, whose genome is described here, was isolated from the fecal flora of a 21-year-old French Caucasoid female who suffered from severe anorexia nervosa. Bacteroides timonensis is a Gram-negative, obligate anaerobic bacillus. Here we describe the features of this organism, togeth...
