Abstract

Fifty-two unencapsulated strains of Staphylococcus aureus, including strains of Wood 46 and Cowan I, formed compact colonies in fibronectin -soft agar. However, 20 encapsulated strains of Staphylococcus aureus and 50 strains of Staphylococcus epidermidis showed diffuse growth in the medium. The results suggest that another possible cellular factor, other than protein A, is involved in the binding of the cell surface with fibronectin and that it would be one of factors in forming compact colonies in serum-soft agar.

摘要

52株未包膜的金黄色葡萄球菌，包括Wood 46菌株和Cowan I菌株，在纤连蛋白软琼脂中形成紧密菌落。然而，20株包膜的金黄色葡萄球菌和50株表皮葡萄球菌在该培养基中呈弥漫性生长。结果表明，除蛋白A外，另一种可能的细胞因子参与了细胞表面与纤连蛋白的结合，并且它可能是在血清软琼脂中形成紧密菌落的因素之一。
