Abstract
This study described the use of species-specific PCR in combination with SNaPshot mini-sequencing to achieve species identification and strain differentiation in Lactobacillus rhamnosus. To develop species-specific PCR and strain subtyping primers, the dnaJ gene was used as a target, and its corresponding sequences were analyzed both in Lb. rhamnosus and in a subset of its phylogenetically closest species. The results indicated that the species-specific primer pair was indeed specific for Lb. rhamnosus, and the mini-sequencing assay was able to unambiguously distinguish Lb. rhamnosus strains into different haplotypes. In conclusion, we have successfully developed a rapid, accurate and cost-effective assay for inter- and intraspecies discrimination of Lb. rhamnosus, which can be applied to achieve efficient quality control of probiotic products.
