title: Phenotypic differences between commercial Lactobacillus rhamnosus GG and L. rhamnosus strains recovered from blood.
abstract: The isolation of clinical isolates that are indistinguishable, by molecular methods, from the probiotic strain of Lactobacillus rhamnosus GG has been reported. We compared the virulence potential of these clinical isolates with that of the probiotic strain. It was observed that all isolates differed significantly in 1 or more phenotypic properties.
