The genus Mycobacterium has over 190 species within it, with many serious human pathogens. We cover only a fraction of these in this database, since most do not cause vulvovaginal or urinary tract infections in humans (that we are aware of, yet).
Mycobacterium are slow growing, fastidious microbes that are not truly gram-positive or gram-negative. Some colonies will produce pigments of various colours, like various shades of yellow, orange, or tan.
