Mycolicibacter
''Mycolicibacter'' is a genus of Gram-Positive rod-shaped bacteria in the family ''Mycobacteriaceae'' from the order Mycobacteriales. Members of ''Mycolicibacter'' were demarcated from the larger genus ''Mycobacterium'' in 2018 by Gupta et al. based on evidence from various phylogenetic trees constructed based on conserved genome sequences, comparative genomic analyses and average amino acid identity values. In addition to this genus, the study proposed the division of ''Mycobacterium'' into a total of five distinct genera, which was met with some resistance by some of the scientific community. The resistance was based on the grounds that ''Mycobacterium'' contains some clinically relevant species and name changes might cause confusion among clinicians and other researchers. In 2020, Yamada et al. analyzed the fundamental morphological properties of the new genera, including the cell diameter, cell length, cell perimeter, cell circularity and aspect ratio, and determined that th ...

Mycobacteria
''Mycobacterium'' is a genus of over 190 species in the phylum Actinomycetota, assigned its own family, Mycobacteriaceae. This genus includes pathogens known to cause serious diseases in mammals, including tuberculosis ('' M. tuberculosis'') and leprosy ('' M. leprae'') in humans. The Greek prefix ''myco-'' means 'fungus', alluding to this genus' mold-like colony surfaces. Since this genus has cell walls with Gram-positive and Gram-negative features, acid-fast staining is used to emphasize their resistance to acids, compared to other cell types. Metabolism and Morphology Mycobacteria are aerobic with 0.2-0.6 µm wide and 1.0-10 µm long rod shapes. They are generally non-motile, except for the species ''Mycobacterium marinum'', which has been shown to be motile within macrophages. Mycobacteria possess capsules and most do not form endospores. ''M. marinum'' and perhaps ''M. bovis'' have been shown to sporulate; however, this has been contested by further research. The disti ...

Mycolicibacter Terrae
''Mycolicibacter terrae'' (formerly ''Mycobacterium terrae'') is a slow-growing species of mycobacteria. It is an ungrouped member of the third Runyon (nonchromatogenic mycobacteria). It is known to cause serious skin infections, which are "relatively resistant to antibiotic therapy". Discovery Richmond and Cummings were the first to isolate ''Mycobacterium terrae'', which they described as "an acid‐fast saprophyte". It is sometimes called the "radish bacillus", because it was isolated from radish water. Pathology This bacterium was originally injected into guinea pigs, and did not cause apparent illness, leading to the misconception that this strain was nonpathogenic. In reality, however, infection by this organism can cause disease of the joints, tendons, lungs, gastrointestinal tract, and genitourinary tract. In humans, symptoms of infection include swelling, lesions, and inflammation, and may mimic the symptoms of osteoarthritis. Uses This bacterium is used to study ef ...
