Is mycobacterium tubercolosis a motie bacillus? forms spores? stains with what? aerobic/anaerobic? shape?
MTB is one of many aerobic, rod shaped, immotile mycobacterium (avium, leprae, bovis) that are acid fast. Mycobacterium species, along with members of a related genus Nocardia, are classified as acid-fast bacteria due to their impermeability by certain dyes and stains. They are typically stained by the Ziehl-Neelsen stain. Infection produces both humoral and cell mediated (mostly) immunity. MTB produces spores
