This paper presents a review of the theories based on wetting measurements/interfacial thermodynamics most frequently used to explain bacterial adhesion to solid surfaces. The physical meaning of data stemming from the application of the different theories is discussed and compared with current knowledge on interactions between components of matter. It is underlined that existing theories are either in disagreement with accepted knowledge on interfacial interactions or yield conflicting results from a quantitative point of view. It is concluded that, according to the present state of the art, no completely satisfactory theory exists, and that theoretical and experimental difficulties still hinder the understanding of the relationship between surface/interface free energy and bacterial adhesion to solid substrates. The recognition of existing shortcomings should be the first step towards a more satisfactory state of the art.
本文综述了基于润湿度测量/界面热力学的理论，这些理论常用于解释细菌在固体表面的黏附。文中讨论了应用不同理论所得到数据的物理意义，并将其与目前关于物质组分间相互作用的知识进行了比较。文中强调，现有理论要么与公认的界面相互作用知识不一致，要么从定量角度得出相互矛盾的结果。结论是，根据目前的技术水平，不存在完全令人满意的理论，理论和实验上的困难仍然阻碍着对表面/界面自由能与细菌在固体基质上黏附之间关系的理解。认识到现有缺点应是迈向更令人满意的技术水平的第一步。
