Colony morphology, beta hemolysis on horse blood agar, beta-glucuronidase activity, and ability to ferment sucrose and/or trehalose defined two biotypes of Arcanobacterium haemolyticum. One, the smooth type, grew as smooth, beta-hemolytic colonies and was beta-glucuronidase negative but often fermented sucrose and/or trehalose, while the other, the rough type, grew as rough colonies and was nonhemolytic, beta-glucuronidase positive, and negative for sucrose and trehalose fermentation. About 75% of the A. haemolyticum strains studied (n = 138) were of the smooth type. The smooth type predominated in wound infections, while the rough type was isolated almost exclusively from respiratory tract specimens; thus, 84% of the smooth-type strains were derived from wounds and 91% of the rough-type strains were isolated from respiratory tracts.
溶血隐秘杆菌的两种生物型可通过菌落形态、在马血琼脂上的β溶血、β-葡萄糖醛酸酶活性以及发酵蔗糖和/或海藻糖的能力来定义。一种是光滑型，形成光滑的β溶血菌落，β-葡萄糖醛酸酶阴性，但常发酵蔗糖和/或海藻糖；另一种是粗糙型，形成粗糙菌落，不溶血，β-葡萄糖醛酸酶阳性，蔗糖和海藻糖发酵阴性。在所研究的溶血隐秘杆菌菌株中（n = 138），约75%为光滑型。光滑型在伤口感染中占主导，而粗糙型几乎仅从呼吸道标本中分离得到；因此，84%的光滑型菌株来自伤口，91%的粗糙型菌株从呼吸道分离得到。
