Present study was to investigate invitro adhesive properties and invivo colonization potentials of Bacillus subtilis MBTU PBBM1 in Balb/c mice. Spores of MBTU PBBM1 showed a higher hydrophobicity than their vegetative cells. Vegetative cells exhibit capabilities for autoaggregation and coaggregation with enteric pathogens. Invitro adhesion studies revealed that spores of MBTU PBBM1 were found to be more adhesive on intestinal mucous than their vegetative cells. So spores of MBTU PBBM1 were selected for in vivo colonization studies in Balb/c mice. Stable spore counts in the feces observed even after the 4 th day of oral administration of the potential strain reveals the possibility of regermination of the spores in gastrointestinal tract. Measurable spore count of this strain detected in the ileac biopsies confirms colonization capability in small intestine. In vivo studies indicated no observable changes in the total body weight and normal health status in Balb/c mice. In nutshell invitro and in vivo studies revealed that the spores of MBTU PBBM1 have the capability for adhesion and colonization which are desirable probiotic characters.
