BIOPHYSICAL AND SEROLOGICAL CHARACTERISTICS OF SOME NEW ZEALAND BOVINE ENTEROVIRUSES

Summary. Five previously reported New Zealand bovine enteroviruses are further characterised with regard to their hiophysical and serologieal properties. Characteristics studied included heat stabilit>. 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(a-hydroxybenzyl) benzimidazole sensitivity, heat stability and the serogroup of the isolates.
