Coagulase-negative staphylococci are the predominant organisms causing infection of intravasal catheters and implanted plastic material. They are able to adhere to and grow on polymer surfaces. During the course of colonization they produce large amounts of an extracellular slime substance by which they are finally covered completely. It is supposed that this matrix of slime protects the embedded staphylococci against antibacterial substances and natural host defenses. The slime substance is not a true capsule but is loosely bound to the staphylococcal cells. It seems to have interesting biological properties such as an adhesin-like function and the ability to inhibit the lymphoproliferative response of mononuclear cells.
凝固酶阴性葡萄球菌是引起血管内导管和植入性塑料材料感染的主要病原体。它们能够粘附在聚合物表面并在其上生长。在定植过程中，它们会产生大量细胞外黏液物质，最终完全被这种物质覆盖。据推测，这种黏液基质可保护嵌入其中的葡萄球菌免受抗菌物质和天然宿主防御机制的影响。黏液物质并非真正的荚膜，而是松散地附着在葡萄球菌细胞上。它似乎具有有趣的生物学特性，如类黏附素功能和抑制单核细胞淋巴增殖反应的能力。
