Identification of Bifidobacterium spp. using hsp60 PCR-RFLP analysis: An update

A PCR-RFLP technique has been applied on 13 species of Bifidobacterium in order to update a previous study carried out by Baffoni et al. [1]. This method is based on the restriction endonuclease activity of HaeIII on the PCR-amplified hsp60 partial gene sequence, and allows a rapid and efficient identification of Bifidobacterium spp. strains at species and subspecies level.
