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.
