Such diversity at the species level has also been illustrated in studies using traditional microbiological culture. Focusing on Lactobacillus spp. and Bifidobacterium spp., McCartney et al. (1996) showed that different individuals carry a unique collection of strains and that species and strain diversity differed between individuals. Similarly, Reuter (2001) reviewed the existing evidence on the composition of the Lactobacillus and Bifidobacterium moieties of the gut microflora. Agreeing with other workers, Reuter (2001) described distinct populations of lactobacilli and bifidobacteria within individuals and identified species truly autochthonous to the gut, for example Lactobacillus gasseri, L. reuteri and a non-motile variant of I. ruminis (formally Catenabacterium catenaforme), while different combinations of bifidobacterial strains predominated in different age groups, notably, infants, compared with adult volunteers.

Tripeptidases release the amino acid from the iV-terminal position of NH2-XiX-X-COOH tripeptides. They have a broad specificity but preferentially target hydrophobic peptides and do not hydrolyze proline residues. The only tripeptidase currently identified in LAB is PepT. The pepTgene is present in all LAB genomes and can occur as two paralogous genes in some LAB (Lact. acidophilus, Lact. johnsonii, and Lactobacillus gasseri).

Pioneering works isolated several Streptococcus sp. and Lactobacillus sp. strains from the vagina of healthy cows (Otero et al. 2006) and reported promising results using Lactobacillus gasseri isolates, which showed inhibitory activity against Staphylococcus aureus in vitro (Otero and Nader-Macias 2006).
