Lactobacillus Rhamnosus

Lactobacillus rhamnosus is a bacterium that was originally considered to be a subspecies of L. casei, but later genetic research found it to be a species of its own. Some strains of L. rhamnosus are being used as probiotics. The species is sometimes used in yogurt and other dairy products. Some studies have been done on its in vivo effects. While frequently considered a beneficial organism, L. rhamnosus has been discovered to be pathogenic in certain circumstances.
