BACKGROUND Cell surface pili in Gram positive bacteria have been reported to orchestrate the colonization of host tissues, evasion of immunity and the development of biofilms. So far, little if any information is available on the presence of pilus-like structures in human gut commensals like bifidobacteria. RESULTS AND DISCUSSION In this report, Atomic Force Microscopy (AFM) of various bifido...
For six strains of Bifidobacterium bifidum (Lactobacillus bifidus), fermentation balances of glucose, lactose, galactose, mannitol, and xylose were determined. Products formed were acetate, l(+)-lactate, ethyl alcohol, and formate. l(+)-Lactate dehydrogenase of all strains studied was found to have an absolute requirement for fructose-1,6-diphosphate. The phosphoroclastic enzyme could not be de...
Bifidobacteria represent one of the dominant groups of microorganisms colonizing the human infant intestine. Commensal bacteria that interact with a eukaryotic host are believed to express adhesive molecules on their cell surface that bind to specific host cell receptors or soluble macromolecules. Whole-genome transcription profiling of Bifidobacterium bifidum PRL2010, a strain isolated from in...
enterohemorrhagic escherichia coli (ehec), such as e. coli o157:h7, are emerging food-borne pathogens worldwide. this micro-organism can damage the epithelial tissue of the large intestine. the cytotoxic effects can be neutralized by probiotics such as bifidobacterium bifidum. probiotics are viable cells that have beneficial effects on the health of the host. the preventing activity of b. bifid...
Complex oligosaccharides from human milk (HMO) possess an antimicrobial activity and can promote the growth of bifidobacteria such as Bifidobacterium bifidum and Bifidobacterium longum subsp. infantis. In addition, fermentation of carbohydrates by bifidobacteria can result in the production of metabolites presenting an antivirulence effect on several pathogenic bacteria. Whey is rich in complex...
Freeze dried probiotic pineapple lassi powder was developed using Bifidobacterium bifidum (NCDC 235). Quality aspects were determined in terms of physico-chemical parameters, vitamin composition and probiotic viability. Storage changes were monitored at 25±20 °C and -18±20 °C for one year. The reconstituted lassi has carbohydrate content of 22.2 per cent, thiamin 2 mg which meets 2/3rd of sugge...
Recent data point at the similarity between the perianal and vaginal microflora in terms of Lactobacillus species involved. Bacterial vaginosis, the most common perturbation of the vaginal microflora involving primarily overgrowth of Gardnerella vaginalis, has also been suggested to involve a recto-vaginal pathway. We addressed this issue with regard to bacteria of the Bifidobacteriaceae family...
