The Lactobacillus microflora in the faeces of two infants was followed in the days after weaning. All colonies isolated at the highest dilution were Lactobacillus casei subsp. casei . They were identified to strain level by plasmid profile, total soluble cell protein and surface cell protein pattern. Two dominant strains of L. casei subsp. casei were identified on successive days, which suggests that these were permanent members of the infant bowel microflora.
