Mycobacterium conspicuum 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.
Gram-positive and nonmotile acid-fast coccobacilli. Does not form spores, capsules or aerial hyphae.
Colony characteristics
- Dysgonic and nonphotochromogenic, pale yellow colonies on Löwenstein-Jensen agar.
Physiology
- Slow growth on Löwenstein-Jensen medium at temperatures between 22 and 31 °C (72 and 88 °F) after 2–3 weeks.
- Susceptible to ethambutol, rifampin, streptomycin, resistant to pyrazinamide.
- Synthesis of α- and keto-mycolates and wax esters.
- no tolerance to 5% NaCl, positive for Tween 80 hydrolysis and for 10-day-arylsulfatase. Negative for production of nicotinic acid, acetamidase, benzamidase, urease, isonicotinamidase, nicotinamidase, pyrazinamidase, succinidamidase, nitrate reductase and tellurite reduction.
Pathogenesis
Opportunistic pathogen, disseminated mycobacteriosis, Biosafety level 2.
