Abstract

A mechanism of neutralization of virus infectivity by antibody is described and related to the immune defences in vivo. The interaction of a particular monoclonal antibody with homologous foot-and-mouth disease virus alters the conformation of the virions to permit penetration of staining reagents. A consequence of this structural alteration is that the RNA genome becomes susceptible to dissociation from the capsid proteins. This mechanism of virus neutralization is irreversible and therefore provides an effective in vivo defence measure against virus attack, complementing the enhanced phagocytosis effected through opsonization of virions. With viruses that can replicate in phagocytes, such a mechanism of virus neutralization could provide a major 'specific' immunological defence against virus invasion.
