The type ⦠Although the strains of this group are commercially valuable as probiotics, the taxonomic status and nomenclature of the L. casei group have long been contentious because of the difficulties in identifying these three species by using the most frequently used genotypic methodology of 16S rRNA gene sequencing. The bacteria from this species are often found in chains, and are gram positive, anaerobic, and rod shaped. This bacterium is part of the Lactobacillus family and plays a role in several digestive functions. Classification. This species of Lactobacillus was originally considered to be a subspecies of Lactobacillus casei; however, further genetic research determined that Lactobacillus rhamnosus was a separate species. Bacteremia caused by lactobacilli is rare, and data on its clinical significance is based only on case reports or data in abstract form [2â6]. Lactobacillus casei, Lactobacillus paracasei, and Lactobacillus rhamnosus are phenotypically and genotypically closely related, and together comprise the L. casei group. Assigned by:
