Intestinal mucus alters the ability of probiotic bacteria to bind aflatoxin B1 in vitro.
Several probiotics are known to bind aflatoxin B(1) (AFB(1)) to their surfaces and to adhere to intestinal mucus. In this study, preincubation of two probiotic preparations with either AFB(1) or mucus reduced the subsequent surface binding of mucus and AFB(1), respectively, in a strain-dependent manner.
متن کاملAdherence of probiotic bacteria to human intestinal mucus in healthy infants and during rotavirus infection.
The concentration of fecal mucin and the adhesion of specific probiotics and their combinations in the intestinal mucus of infants during and after rotavirus diarrhea and in healthy children were determined. Mucus was prepared from fecal samples from 20 infants during and after rotavirus diarrhea and from 10 healthy age-matched children. Mucin concentration was determined, and the adhesion of f...
متن کاملAbsence of host specificity for in vitro adhesion of probiotic lactic acid bacteria to intestinal mucus.
Adhesion of probiotic lactic acid bacteria (LAB) has been reported to be host species specific. Host specificity is regarded as a desirable property for probiotic bacteria and therefore recommended as one of the selection criteria. However, previous studies have indicated that LAB originating from one host adhere well also to the mucus of other species. The aim of the study was to investigate t...
متن کاملProtection mechanism of probiotic combination against human pathogens: in vitro adhesion to human intestinal mucus.
In this study we evaluated the ability of commercial strains (L. rhamnosus GG, L. rhamnosus LC705, and P. freudenreichii ssp. shermanii JS) in combination with B. breve 99 or B. lactis Bb12 to inhibit, displace and compete with model pathogens in order to test their influence on the adhesion of selected pathogens to immobilized human intestinal mucus. Our results demonstrate that specific probi...
متن کاملExopolysaccharides produced by probiotic strains modify the adhesion of probiotics and enteropathogens to human intestinal mucus.
Exopolysaccharides (EPSs) are exocellular polymers present in the surface of many bacteria, including Lactobacillus and Bifidobacterium. The genome sequence of several strains revealed the presence of EPS-encoding genes. However, the physiological role that EPSs play in the bacterial ecology still remains uncertain. In this study, we have assessed the effect of EPSs produced by Lactobacillus rh...
