Mycobacterium
''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 disting ...

Mycobacterium Farcinogenes
''Mycobacterium farcinogenes'' is a species of the phylum Actinomycetota (Gram-positive bacteria with high guanine and cytosine content, one of the dominant phyla of all bacteria), belonging to the genus ''Mycobacterium''. Although slow-growing, it is similar to fast-growing species, and is usually classified with them. Description Gram-positive, nonmotile and strongly acid-fast rods. Short or long filaments, bent and branched, in clumps or tangled, lacy network. Colony characteristics Rough, yellow and convoluted colonies. Firmly adherent to medium and surrounded by an iridescent halo. Physiology *Slow growth after 15–20 days on Löwenstein-Jensen medium. Differential characteristics *On the basis of characteristic lipids this species belongs to the genus ''Mycobacterium'' and not to the genus ''Nocardia''. *DNA homology to the closely related species '' Mycobacterium senegalense''. Both species, share an identical 5' 16S rDNA sequence. However, the ITS sequences are di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
