When antibodies bind to the epitopes of an antigen(bacteria) via antigen receptors, the antibodies present the bacteria to a macrophages in a form that they recognize the foreign substance and engulf them. This antibody-antigen "team work" is also known as opsonization

As the list of pathologies and infectious agents are extensive, a related link is shown below.Once the web page is open, click on Figure 10.3. A table is displayed showing the main infectious agents and the pathologies they cause.
Viruses are the only non-biological infectious agents; all otheres are forms of pathogen, which are bacteria.
