This study of microbial adhesion stresses the multiple adhesion concepts and features a molecular approach to its subject. Questions about microbial attachment or adhesion arise both in environmental and applied microbiology, since microbes can attach themselves to rocks or metal pipes, for example. The subject is also important in medical microbiology, since decay-causing microbes attach themselves to teeth and Pseudomonas adhere to surfaces in the lungs of cystic fibrosis patients. It includes a detailed chapter on natural environments which should appeal to researchers in microbiology.
