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
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
