Mycobacterium fortuitum and Mycobacterium chelonei are distinguished unambiguously by the combined use of five test characters: nitrate reductase, beta-glucosidase, acid production from fructose, penicillinase, and trehalase. Typically, M. fortuitum was nitrate reductase positive, beta-glucosidase positive; M. chelonei was nitrate reductase negative, beta-glucosidase negative, penicillinase positive, and trehalase positive and did not produce acid from fructose.
硝酸还原酶、β-葡萄糖苷酶、果糖产酸、青霉素酶和海藻糖酶。通常,偶然分枝杆菌硝酸还原酶阳性、β-葡萄糖苷酶阳性;龟分枝杆菌硝酸还原酶阴性、β-葡萄糖苷酶阴性、青霉素酶阳性、海藻糖酶阳性且不能利用果糖产酸。
