Fecal steroids and bacterial flora in patients with polyposis coli. 1976

A L Watne, and H Y Lai, and T Mance, and S Core

Fecal neutral and acid steroids and bacterial flora have been studied in a series of patients with polyposis coli and normal controls. The patients with polyposis coli showed a higher concentration of cholesterol and primary bile acids, which increased still more after ileorectostomy. The bacterial flora of the patients with polyposis coli showed an anaerobe/aerobe ratio of 2.7/1 with a relative increase in clostridia and bifidobacteria and decrease in eubacteria and bacteroides. After ileorectostomy clostridia disappear, as do rumenococcus, peptostreptococcus, and fusobacteria, whereas eubacteria and lactobacilli decrease and bifidobacteria and bacteroides increase. Eubacteria showed a decrease from normal in the pre- and postoperative patients with polyposis coli and paralleled the reduction of cholesterol to coprostanol.

D000328	Adult	A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available.	Adults
D001419	Bacteria	One of the three domains of life (the others being Eukarya and ARCHAEA), also called Eubacteria. They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive.	Eubacteria
D013261	Sterols	Steroids with a hydroxyl group at C-3 and most of the skeleton of cholestane. Additional carbon atoms may be present in the side chain. (IUPAC Steroid Nomenclature, 1987)	Sterol
