N2 - In the present study, polyphasic analysis [cultivation, combined with the fingerprinting of individual isolates, and denaturing gradient gel electrophoresis (DGGE)] was applied to study whether similar features concerning the diversity and temporal stability of selected bacterial groups could be detected intra-individually in two different niches – the oral cavity and the colon – from ten adult volunteers consuming probiotics. The predominant bacterial microbiota, Clostridium coccoides–Eubacterium rectale group and bifidobacterial populations, were generally stable in salivary and faecal samples, with the greater diversity seen in faeces. Furthermore, different species predominated at the two different sites. Lactobacillus group DGGE profiles were unstable, yet the intra-individual profiles from faecal and salivary samples collected at the same time resembled each other. The ingested probiotic product did not affect the stability of the bacterial groups studied. The culture-based analysis showed that most subjects harboured identical indigenous Lactobacillus genotypes in saliva and faeces (Lactobacillus rhamnosus, Lactobacillus gasseri, Lactobacillus paracasei and Lactobacillus plantarum group). Thus, identical indigenous lactobacilli were able to inhabit both ends of the orogastrointestinal tract, whereas the composition of the other bacterial groups studied varied between the two sites.
