Model of the Mycobacterium spp. cell envelope with 3-D protein structures. 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. [8] Mycobacteria possess capsules and most do not form ...
Mycobacteroides is a genus of Gram-Positive rod-shaped bacteria in the family Mycobacteriaceae from the order Mycobacteriales. [1]Members of Mycobacteroides 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 ...
Mycolicibacterium is a genus of Gram-positive rod-shaped bacteria in the family Mycobacteriaceae from the order Mycobacteriales. [1]Members of Mycolicibacterium 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 ...
Mycobacterium avium complex is a group of mycobacteria comprising Mycobacterium intracellulare and Mycobacterium avium that are commonly grouped because they infect humans together; this group, in turn, is part of the group of nontuberculous mycobacteria. These bacteria cause Mycobacterium avium-intracellulare infections or Mycobacterium avium ...
Mycobacterium tuberculosis (M. tb), also known as Koch's bacillus, is a species of pathogenic bacteria in the family Mycobacteriaceae and the causative agent of tuberculosis. [ 1 ] [ 2 ] First discovered in 1882 by Robert Koch , M. tuberculosis has an unusual, waxy coating on its cell surface primarily due to the presence of mycolic acid .
Mycolicibacillus is a genus of Gram-Positive rod-shaped bacteria in the family Mycobacteriaceae from the order Mycobacteriales. [1]Members of Mycolicibacillus 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 ...
Mycobacterium tuberculosis group bacteria are 1.0-4.0 μm long by 0.2-0.3 μm wide in tissues. In culture, they may appear as cocci, or as bacilli up to 6-8 μm long. [citation needed] The bacteria stain Gram-positive, acid-fast. The cell wall contains as high as 60% lipid, giving the mycobacteria their hydrophobic characteristics, slow growth ...
Mycobacterium smegmatis is an acid-fast bacterial species in the phylum Actinomycetota and the genus Mycobacterium.It is 3.0 to 5.0 μm long with a bacillus shape and can be stained by Ziehl–Neelsen method and the auramine-rhodamine fluorescent method.
