The composition and diversity of the gut microbiota are known to be different between babies and adults. The aim of this project was to compare the level of bifidobacteria between babies and adults and to investigate the influence of lifestyle factors on the level of this bacterium in the gut. During this study, the levels of bifidobacteria in 10 human babies below 2 years of age were compared ...

TROJANOVÁ I., RADA V. (2005): Enzymatic activity in fermented milk products containing bifidobacteria. Czech J. Food Sci., 23: 224–229. Streptococcus thermophilus, Lactobacillus delbrueckii subsp. bulgaricus and Bifidobacterium animalis strains were tested for α-galactosidase, β-galactosidase and α-glucosidase activities. Commercially available yoghurts with bifidobacteria were also tested. Whi...

BACKGROUND AND OBJECTIVES Bifidobacteria colonize the gut after the first week of life and remain an important component of the gut microbiota in infancy. This study was carried out to characterize the diversity and number of bifidobacteria colonizing the gut in Indian neonates and to investigate whether asymptomatic infection with rotavirus in the first month of life affected gut colonization ...

Intestinal microbiota plays an important role in human health by influencing metabolic activities that result in the creation of energy and absorbable nutrients, a barrier to the colonization of pathogens, and stimulation of the immune system. The development of fecal microbiota in neonates is crucial because those bacteria are the first to colonize the sterile intestine of the neonates and, th...

in this research, the survival of probiotic microorganisms in yogurts stored at room temperature (cold chain interruption conditions) was studied. milk inoculated with yogurt bacteria (mixed culture of streptococcus thermophilus and lactobacillus delbrueckii ssp. bulgaricus) and a single probiotic culture (l. acidophilus la-5 or bifidobacterium lactis bb-12 or l. rhamnosus hn001 or l. paracasei...

in the present work, the effect of milk supplementation on viability of yogurt bacteria (streptococcus thermophilus and lactobacillus delbrueckii subsp. bulgaricus) and probiotic bacteria (lactobacillus acidophilus and bifidobacteria) was studied during yogurt manufacture and thirty three days storage. incubation time to reach ph value of 4.5 was greatly affected by the addition of casein fract...

Probiotic organism Bifidobacteria was isolated from the faeces of breast-fed infants at Universiti Putra Malaysia. Trypticase phytone peptone yeast extract agar (TPY) was used as a selective media for the isolation. Morphological examination of the isolates indicated that Bifidobacteria was Gram-positive rods in nature, curved with characteristics of V and Y shapes. The organisms were non-catal...

Members of the genus Bifidobacterium are abundant in the stool of most human infants during the initial exclusively milk-fed period of life, especially at an age of 2–3 months (Harmsen et al., 2000; Favier et al., 2002; Mariat et al., 2009; Coppa et al., 2011; Turroni et al., 2012; Yatsunenko et al., 2012; Tannock et al., 2013; Barrett et al., 2015). Bifidobacteria dominate the stool microbiota...

The main purpose of this study was to investigate bifidobacteria flora in fecal samples from children with rotavirus infection and determine the significance of their selected probiotic properties for improvement of health status. Enzyme-linked immunosorbent assay was used to identify rotavirus antigen in fecal samples from 94 patients with gastroenteritis and from 30 without gastroenteritis. B...

Bifidobacteria are commensal microoganisms found in the gastrointestinal tract. Several strains have been attributed beneficial traits at local and systemic levels, through pathogen exclusion or immune modulation, among other benefits. This has promoted a growing industrial and scientific interest in bifidobacteria as probiotic supplements. However, the molecular mechanisms mediating this cross...
