Sorbitol-fermenting Bifidobacteria are indicators of very recent human faecal pollution in streams and groundwater habitats in urban tropical lowlands.
Sorbitol-fermenting Bifidobacteria (SFB) proved to be an excellent indicator of very recent human faecal pollution (hours to days) in the investigated tropical stream and groundwater habitats. SFB were recovered from human faeces and sources potentially contaminated with human excreta. SFB were undetectable in animal faeces and environmental samples not contaminated with human faeces. Microcosm...
متن کاملCharacterization of 'faecal streptococci' as indicators of faecal pollution and distribution in the environment.
The recent revision of the taxonomy of 'faecal streptococci' prompted us to verify the importance of identifying the species of this group of cocci. During a study carried out to assess the hygienic quality of environmental samples from a variety of sources, we isolated 198 strains named faecal streptococci on the basis of conventional international tests (EVA broth multiple tube test) used for...
متن کاملBifidobacteria as indicators of faecal contamination along a sheep meat production chain.
AIMS The potential use of bifidobacteria as indicators for faecal contamination was studied along a sheep meat production and processing chain. The levels of bifidobacteria were compared with those of Escherichia coli. Total viable counts were followed along the chain (244 samples). METHODS AND RESULTS Forty-three per cent of the samples contained bifidobacteria, of which 15% were solely dete...
متن کاملDetection of somatic coliphages as indicators of faecal contamination in estuarine waters.
The appearance of enteric disease outbreaks associated with the use of waters considered bacteriologically suitable, calls for the search of new and more precise indicators. Samples of estuarine water were collected in order to quantify E. coil and E. coil ATCC 13706 somatic coliphages and to compare the usefulness of the latter to detect faecal contamination when the concentration of tradition...
متن کاملEffects of inulin on faecal bifidobacteria in human subjects.
A controlled study with eight healthy free-living subjects was carried out, in which energy intake was adjusted to the individual energy requirements. On administration of inulin, blood lipids, the faecal microflora, short-chain fatty acids and accompanying gastrointestinal symptoms were characterized in order to investigate the long-term effect of inulin. During the run-in phase (8 d), subject...
