Abstract

In an in vitro study, we have quantitatively evaluated the capability of seven different types of silicone to retain a Staphylococcus aureus strain, isolated from a surgical wound. All the silicone specimens were taken from prostheses already used in plastic or ophthalmological surgery. Two polymers were used as controls: polystyrene, because of its known capability to favour in vitro bacterial recovery, and nylon, for its bacterial repellence. The results show that all silicones are suitable substrata for Staphylococcus aureus. However, there are some differences among silicone types. The amounts of bacteria retained from silicone oils are greater than or equal to those obtained from the positive control material.

摘要

在一项体外研究中，我们定量评估了七种不同类型的硅酮保留从手术伤口分离出的金黄色葡萄球菌菌株的能力。所有硅酮标本均取自已经用于整形或眼科手术的假体。使用了两种聚合物作为对照：聚苯乙烯，因其已知有利于体外细菌复苏的能力；以及尼龙，因其具有抗菌性。结果表明，所有硅酮都是金黄色葡萄球菌的合适基质。然而，不同类型的硅酮之间存在一些差异。从硅油中保留的细菌数量大于或等于从阳性对照材料中获得的细菌数量。
