Hosta

Mycolicibacterium alvei 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 Mycolicibacterium.

Description

Gram-positive, nonmotile and acid-fast rods (1–3 μm × 0.5–0.7 μm).

Colony characteristics

• Colonies are eugonic, rough and nonpigmented.

Physiology

• Colonies occur within 5 days at 30 °C (optimum temperature, no growth at 45 °C) on Löwenstein–Jensen medium and on Middlebrook 7H10 agar.
• The type strain is resistant to D-cycloserine, streptomycin, isoniazid, rifampin, and thiacetazone
• The type strain is susceptible to kanamycin, capreomycin and high levels of isoniazid.

Differential characteristics

• Differentiation from all other mycobacterial species by its unusual mycolate pattern.

Pathogenesis

• Not associated with disease.
• Biosafety level 1

Type strain

First isolated from water samples, from soil and human sputum samples in Spain.
