Intertypic differentiation and detection of intratypic variants among canine and phocid morbillivirus isolates by kinetic neutralization using a novel immunoplaque assay.

Institute of Virology, Hannover Veterinary School, Germany.


Intertypic antigenic differences and the intratypic variability of the closely related canine (CVD) and phocid distemper viruses (PDV) were examined using a molecular (monoclonal antibodies specific for the H- and F-glycoproteins) and a functional (kinetic neutralization, KN) approach. KN studies were carried out using a novel immunoplaque technique which combined conventional plaque assay and antigen-specific enzyme-immunostaining techniques. Morbillivirus isolates of canine and phocid origin clearly formed two separate groups. Minor antigenic differences were also evident within each cluster. A distemper isolate of mustelid origin was distinguishable from both CDV- and PDV-like prototype viruses by kinetic neutralization.
