| 摘要 |
This invention relates to a method of selecting nonpathogenic bacterial strains capable of binding to the receptor sites for tissue adhesion of pathogenic bacterial strains, comprising the steps consisting in:a) bringing the said receptors into contact in vitro with a bacterial strain to be tested;b) adding an antibody directed against the said receptors, the said antibody being optionally labelled in a detectable manner;c) in the case where the said antibody is itself not labelled in a detectable manner, adding an agent for detecting the antibody;d) detecting the presence of the complex formed between the said antibody and the said receptors.
