“…In order to colonise GI tract of Swiss mice, approximately 109 cells of the mixture of six strains of Bifidobacterium were introduced into the animals for seven days. Colonisation of GI tract of mice by 108 cells of Bifidobacterium bifidum and Lactobacillus casei strain GG has been reported (13,14). At the first stage of the ex-periment, zero or small variations were observed among the strains of Bifidobacterium in each mouse.…”

The potential of six strains of Bifidobacterium to colonise the gastrointestinal (GI) tract of Swiss mice , their interaction i n the GI tract of Swiss mice and their in-vitro characteristics were investigated. This study revealed that a strain of Bifidobacterium that was isolated from a C57BL/10 ScSn mouse was capable of colonising the GI tract of Swiss mice and remaining there for at least one month. The in-vitro studies showed that this strain had the highest capability among the six strains to adhere to the intestinal tissue of BALB/c mice. This strain grew in presence of 2% bile and lost less than 10-fold viability at pH 2.5.

“…Among the factors contributing to the development of the gut mucosal barrier, the intestinal microflora plays an important role. In the newborn, bacterial colonization is established gradually and greatly depends on the nutritional context‐that is, breast feeding or formula feeding (1). Bifidobacteria constitute the dominant microflora in breast‐fed infants (2), but the weaning period is associated with important changes in the gut flora (3,4).…”

Background:The respective effect of milk and fermented milks on intestinal barrier capacity and on sensitization to β‐lactoglobulin was studied using a guinea pig model of cow's milk allergy.Methods:Guinea pigs were fed a control diet or the same diet supplemented with milk, fermented milk (Streptococcus thermophilus and Bifidobacterium breve), or dehydrated fermented milk. Intestinal barrier capacity to macromolecules was assessed in an Ussing chamber, and sensitization to cow's milk protein was measured by systemic anti‐β‐lactoglobulin immunoglobulin G1 titers and by intestinal anaphylaxis, the latter assessed by the β‐lactoglobulin‐induced increase in short‐circuit current of jejunal fragments (ΔIscβ‐LG).Results:The electrical resistance of jejunum was similar in the four groups (∼80 Ω/cm2) suggesting the same paracellular permeability. The transport of 14C‐β‐lactoglobulin from mucosa to serosa was significantly decreased in the animals fed dehydrated fermented milk (403 ± 131 ng/hr·cm2) compared with that in control animals or animals fed milk (767 ± 250 ng/hr·cm2 and 749 ± 475 ng/hr·cm2, respectively; p < 0.05). Milk fermentation did not modify native β‐lactoglobulin concentration but anti‐β‐lactoglobulin immunoglobulin G1 titers were higher in fermented milk and dehydrated fermented milk (log10 titer = 2.86 and 2.79, respectively) than in guinea pigs fed milk (log10 titer = 2.5; p < 0.007). However, β‐lactoglobulin‐induced intestinal anaphylaxis remained the same in the three groups (ΔIscβ‐LG, 9.6 ± 4.1 µA/cm2, 8.5 ± 4.3 µA/cm2, and 8.5 ± 3.4 µA/cm2 in milk‐fed, fermented milk‐fed, and dehydrated fermented milk‐fed guinea pigs, respectively).Conclusions:The intestinal barrier capacity to milk proteins seems to be reinforced by dehydrated fermented milk, but milk and fermented milks are equally efficient in inducing cow's milk allergy in guinea pigs.
