Biophysical and serological characteristics of some New Zealand bovine enteroviruses.

Five previously reported New Zealand bovine enteroviruses are further characterised with regard to their biophysical and serological properties. Characteristics studied included heat stability, buoyant density, virus replication, plaque production and thin section electron microscopy. Serological tests indicated the isolates belonged to two different serogroups which showed only limited relationships with U.S. serotypes BES 1, 3 and 4. A correlation was noted between 2(alpha-hydroxybenzyl) benzimidazole sensitivity, heat stability and the serogroup of the isolates.
