Initial screening of tubercle bacilli with 2-thiophene carboxylic acid hydrazide (TCH) or 2-furoic acid hydrazide (FAH) separates them into two groups. Resistant strains are Mycobacterium tuberculosis. Sensitive strains include M. tuberculosis, M. bovis and BCG which are separated by nitratase and oxygen requirement tests. Pyrazinamide sensitivity tests allow M. bovis and M. africanum to be identified. The niacin test is not used. Most strains of M. tuberculosis from Europeans are resistant to TCH and FAH and are in phage groups A and B, while most strains from Asians are sensitive and are in phage group I.
用2-噻吩羧酸酰肼（TCH）或2-呋喃甲酸酰肼（FAH）对结核杆菌进行初步筛选可将它们分为两组。耐药菌株为结核分枝杆菌。敏感菌株包括结核分枝杆菌、牛分枝杆菌和卡介苗，可通过硝酸酶和需氧试验将它们区分开来。吡嗪酰胺敏感性试验可鉴别牛分枝杆菌和非洲分枝杆菌。不再使用烟酸试验。欧洲人的大多数结核分枝杆菌菌株对TCH和FAH耐药，属于噬菌体A组和B组，而亚洲人的大多数菌株敏感，属于噬菌体I组。
