Lacticaseibacillus casei
species of bacterium
Lacticaseibacillus casei is an organism that belongs to the largest genus in the family Lactobacillaceae, a lactic acid bacteria (LAB), that was previously classified as Lactobacillus casei. This bacteria has been identified as facultatively anaerobic or microaerophilic, acid-tolerant, non-spore-forming bacteria.
This species is a non-sporing, rod-shaped, gram positive microorganism that can be found within the reproductive and digestive tract of the human body. Since L. casei can survive in a variety of environmental habitats, it has and continues to be extensively studied by health scientists. Commercially, L. casei is used in fermenting dairy products and its application as a probiotic.
In bacteraemia, it is regarded to be similar in pathogenicity to Lactobacillus and associated with infective endocarditis.
Taxonomy
The taxonomy of the L. casei group has been debated for several years because researchers struggled to differentiate between the strains of L. casei and L. paracasei using methods of traditional bacteriology, i.e. phenotypic, physiological, and biochemical similarities. In the 1990s, researchers began to realize that the type strain for L. casei, ATCC 393, does not quite match most other strains classified as "L. casei" by then. To solve this discrepancy, Dellaglio et al.
Begin with the source’s own compact description: “Lacticaseibacillus casei” is species of bacterium. The dossier treats that line as a proposition to test through Lacticaseibacillus, casei and species, not as a finished interpretation.
Why this record matters
The phrase “species of bacterium” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Feb 20, 2026. The linked authority identifier is Q139777. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
