Twenty-seven coagulase-negative and deoxyribonuclease-positive staphylococci were isolated from more than 3000 specimens from human infections. The strains were tested by conventional biochemical tests and by simple agar plate assays for production of different extracellular enzymes and toxins. Three strains were lysed by S. epidermidis phages and 7 strains by S. aureus phages. All strains produced thermolabile nuclease but only 21 strains produced thermostable nuclease. The investigated strains belonged to a heterogeneous intermediate group sharing characters of S. aureus and S. epidermidis. Tests for production of coagulase and thermostable nuclease should be used in the classification of these intermediate strains in diagnostic bacteriology.
从3000多份人类感染标本中分离出27株凝固酶阴性、脱氧核糖核酸酶阳性葡萄球菌。通过传统生化试验和简单琼脂平板试验对这些菌株进行检测，以确定其不同细胞外酶和毒素的产生情况。3株菌株可被表皮葡萄球菌噬菌体裂解，7株可被金黄色葡萄球菌噬菌体裂解。所有菌株均产生不耐热核酸酶，但只有21株产生耐热核酸酶。所研究的菌株属于一个异质性中间组，兼具金黄色葡萄球菌和表皮葡萄球菌的特征。在诊断细菌学中，凝固酶和耐热核酸酶产生试验应用于这些中间菌株的分类。
