Implants of two capillary multifilament suture materials, braided polyester and twisted polyamide with cover, in tissue infected with Staphylococcus aureus were studied with light microscopy and transmission electron microscopy. In the tissue around both suture materials there was a pronounced inflammatory cell reaction. Staphylococci were found between the filaments of both materials. Some ingrowth of granulation tissue with inflammatory cells close to the exterior thread surface was seen in braided polyester suture. No such infiltration was seen in the suture consisting of twisted polyamide with cover. Bacteriologic studies showed faster elimination of staphylococci from the braided polyester than from the twisted polyamide implants. The capacity of leukocytes to penetrate into a capillary multifilament material presumably is dependent on the structure of the suture thread. Bacteria which are enclosed in the interstices of multifilament suture material, and protected from the phagocytic activity of leukocytes, can sustain and prolong an infection.
对金黄色葡萄球菌感染组织中植入的两种毛细血管多丝缝合材料（编织聚酯和带覆盖层的捻制聚酰胺）进行了光学显微镜和透射电子显微镜研究。在两种缝合材料周围的组织中均有明显的炎性细胞反应。在两种材料的细丝之间均发现了葡萄球菌。在编织聚酯缝合线中，可见靠近外螺纹表面有一些肉芽组织向内生长并伴有炎性细胞。在带覆盖层的捻制聚酰胺缝合线中未见到此类浸润。细菌学研究表明，与捻制聚酰胺植入物相比，编织聚酯中的葡萄球菌清除速度更快。白细胞穿透毛细血管多丝材料的能力可能取决于缝线的结构。包裹在多丝缝合材料间隙中且免受白细胞吞噬活性影响的细菌可维持并延长感染。
