species has been extensively characterized, the ecology of this genus has been explored by metataxonomic techniques that are accurate down to the genus or phylogenetic group level only. Thus, the distribution of lactobacilli in environmental or processed food samples is relatively unexplored. The profiling protocol described here relies on the use of the internal transcribed spacer to perform an accurate classification in a target population of lactobacilli with a <0.006-ng/μl sensitivity. This approach was used to analyze five sample types collected from both human and animal host-associated microbiota, as well as from the cheese production chain. The availability of a tool for species-level profiling of lactobacilli may be highly useful for both academic research and a wide range of industrial applications.
