Abstract The number of bifidobacteria in faeces and intestinal contents has been shown to be reduced with increasing age of the subject. The adhesion of four Bifidobacterium strains was tested to mucus isolated from subjects of different age. All strains bound significantly less to mucus isolated from elderly subjects, compared to mucus from the other age groups. Two of the tested strains also showed decreased adhesion to mucus isolated from 6-month-old and adult subjects compared to the adhesion to mucus from 2-month-old subjects. The results suggest that reduced adhesion may be a factor involved in the decreasing colonisation of elderly subjects by bifidobacteria.
