The basis for a classification of bovine enteroviruses

Further characterization of bovine enteroviruses isolated in Poland

“…Moreover, the antigenic relationships to the two serological groups identified by LA PLaCA et al (5), and the susceptibility to the inhibitory activity of 2-(~-bydroxybenzyl)benzimidazole (HBB) (6) of two prototype strains from each group have been investigated. For this purpose one prototype strain from each group has been studied in negatively stained preparations with the electron microscope.…”

“…All the tests and virus stock preparations were carried out, in primary calf kidney cell cultures (7). Neutralization tests were performed using the "decreasing virus --constant serum" technique employing chicken immune sera (5). The sensitivity to HBB (final concentration : 5 ~g/ml) was studied using the technique of PORTOLANI et al (6), and electron microscopy was carried out following the method of LA PI,ACA and PO~TOLXNI (9).…”
