Mycobacterium motility

Sliding motility in mycobacteria Mycobacteria are nonflagellated gram-positive microorganisms. Previously thought to be nonmotile, we show here that Mycobacterium smegmatis can spread on the surface of growth medium by a sliding mechanism. M. smegmatis spreads as a monolayer of cells which are arranged in pseudofilaments by close c Motility in mycobacteria was described for the first time in 1999. It was reported that Mycobacterium smegmatisand Mycobacterium aviumcould spread on the surface of solid growth medium by a sliding mechanism and that the presence of cell wall glycopeptidolipids was essential for motility

The RGM Mycobacterium obuense, Surface spreading motility shown by a group of phylogenetically related, rapidly growing pigmented mycobacteria suggests that motility is a common property of mycobacterial species but is restricted to smooth colonies. J Bacteriol Mycobacterium marinum is a close relative of Mycobacterium tuberculosis that can cause systemic tuberculosis-like infections in ectotherms and skin infections in humans. Sliding motility correlates with biofilm formation and virulence in most bacteria. In this study, we used a sliding motility assay to screen 2,304 transposon mutants of M. marinum NTUH-M6885 and identified five transposon. Most strains of mycobacteria form more than one kind of colony, but colonies of some species, as as M. tuberculosis, are regularly rough; some, as of M. intracellulare on primary culture from clinical specimens, are more commonly smooth Mycobacterium smegmatis spreads over soft agar surfaces by sliding motility, a form of passive motility in which growth and reduction of surface adhesion enable the bacteria to push each other outwards. Hence, sliding motility is mostly associated with round colonies. However, M. smegmatis sliding colonies can also produce long, pointed dendrites

Mycobacterium abscessus. Mycobacterium abscessus (MAB) is a rapidly growing mycobacterial species that causes a wide spectrum of human infections,91 including lung, skin and soft tissue infection, disseminated infection, lymphadenitis, postoperative catheter-related infection, and bone and joint infection. From: Tuberculosis, 2013 The absence of glycopeptidolipids (GPLs) abolishes the ability of mycobacteria both to slide over the surface of motility plates and to form biofilms on polyvinyl chloride. In a screen for biofilm-defective mutants of Mycobacterium smegmatis mc2155, a new mutant was obtained that resulted in partial inhibition of both processes and also showed an intermediate rough colony morphology. Mycobacterium tuberculosis: Is the pathogen responsible for tuberculosis. Nonmotile, acid-fast, non-sporing, Gram-positive rod. Klebsiella pneumoniae: Found in soil, water, grain, fruits, vegetables and in the intestinal tracts of humans and animals. Causes septicemia, enteritis and meningitis in infants For the cell motility assay, mycobacteria were cultured in motility medium containing 7H9 supplemented with ADC and 0.35% agarose. Pseudomonas aeruginosa ATCC27853 [ 29 ] cultured in motility medium was used as a positive control in the drop-collapsing test. Table Mycobacterium smegmatis is a non-motile bacillus, a rod-shaped bacteria 3-5 micrometers long with no means of locomotion. They grow rapidly into a colony called a biofilm, doubling in population through cell division every three to five days. They are classified as Gram-positive bacteria, with cell walls that absorb standard violet stains used.

  3. Mycobacterium marinum Escapes from Phagosomes and Is Propelled by Actin-based Motility Mycobacteria are responsible for a number of human and animal diseases and are classical intracellular pathogens, living inside macrophages rather than as free-living organisms during infection
  4. Due to mycobacteria being nonflagellated microorganisms, sliding motility is produced by the expansive forces of the growing bacterial population and cell surface properties that favor reduced friction between the cells and substrate, and the result is the slow movement of a uniform monolayer of cells as a unit [ 14 ]
  5. Mycobacterium abscessus is an opportunistic pathogen causing human diseases, especially in immunocompromised patients. M. abscessus strains with a rough morphotype are more virulent than those with a smooth morphotype. Morphotype switch may occur during a clinical infection

Like Mycobacterium tuberculosis, Mycobacterium marinum is a macrophage pathogen and causes a chronic, systemic tuberculosis-like disease in ectotherms. It grows optimally at 25-35°C but poorly at 37°C and usually causes only localized disease on the cooler sur-faces of humans (Linell and Norden, 1954; Clark and Shepard, 1963) Mycobacterium tuberculosis and related Corynebacterineae synthesize a family of lipomannans (LM) and lipoarabinomannans (LAM) that are abundant components of the multilaminate cell wall and essential virulence factors in pathogenic species.
