Enterobacteria in fecal flora are often reported to be highly resistant. Escherichia coli is the main species; resistance data on other species are rare. To assess the effect of the host's environment, antimicrobial resistance was determined in fecal species of the family Enterobacteriaceae from three populations: healthy people (HP)(n = 125) with no exposure to antimicrobials for 3 months prec...
BACKGROUND The probiotic microorganisms are live normal flora that provide nutritional benefits. When probiotic administered in adequate amounts, they also confer a health benefit on the host. Different mechanisms of probiotic effects include the following: stimulating the immune system, modifying the composition of normal intestinal flora and preventing the carcinogenic activity of fecal enzym...
We tested bile acid oxazoline derivatives of chenodeoxycholic (CDC-OX), 7-ketolithocholic (7-KLC-OX), ursodeoxycholic (UDC-OX), and deoxycholic (DC-OX) as inhibitors of the 7-epimerization of the primary bile acids cholic acid (CA) and CDC in cultures of four species of bacteria and the human fecal flora. The organisms tested elaborate a 7 alpha- and/or 7 beta-hydroxysteroid dehydrogenase (HSDH...
BACKGROUND Animal studies suggest that prebiotics and probiotics exert protective effects against tumor development in the colon, but human data supporting this suggestion are weak. OBJECTIVE The objective was to verify whether the prebiotic concept (selective interaction with colonic flora of nondigested carbohydrates) as induced by a synbiotic preparation-oligofructose-enriched inulin (SYN1...
Some cases of late-onset (regressive) autism may involve abnormal flora because oral vancomycin, which is poorly absorbed, may lead to significant improvement in these children. Fecal flora of children with regressive autism was compared with that of control children, and clostridial counts were higher. The number of clostridial species found in the stools of children with autism was greater th...
Clostridium difficile toxin was checked in fecal extract of 62 ulcerative colitis patients and 62 normal controls, by Elisa and cell culture methods. Clostridium difficile toxin was found in 48.71 percent of ulcerative colitis patients in their acute exacerbations, and in 26.08 percent of cases in their remissions. This toxin was found in the fecal extract of only 3 percent of normal controls. ...
This study was conducted to determine the effect of dietary fructan supplementation on growth performance, nutrient digestibility, meat quality, fecal microbial flora, and fecal noxious gas emission in finishing pigs. A total of 96 finishing pigs [(Yorkshire×Landrace)×Duroc] with an average BW of 73.1±2.5 kg were used in a 6-wk study. Pigs were randomly allotted to 1 of 3 dietary treatments: 1)...
