Virulent strains of Mycobacterium tuberculosis isolated from humans are divisible into five variants by using four tests: oxygen requirement (aerobic or microaerophilic), nitrate reductase activity, susceptibility to pyrazinamide (60 micrograms/ml) and susceptibility to thiophene-2-carboxylic acid hydrazide (5 micrograms/ml). The five variants are referred to as Classical human, Asian human, bovine, African I and African II. The relation of these variants to previously described types is discussed. This simple division has been shown to be useful in epidemiological studies.
需氧情况(需氧或微需氧)、硝酸还原酶活性、对吡嗪酰胺(60微克/毫升)的敏感性以及对噻吩-2-羧酸酰肼(5微克/毫升)的敏感性,可将从人类分离出的结核分枝杆菌强毒株分为五个变种。这五个变种分别称为经典人类型、亚洲人类型、牛型、非洲I型和非洲II型。文中讨论了这些变种与先前描述类型的关系。这种简单的分类已证明在流行病学研究中很有用。
