Abstract

Neutralizing antibody titers to four bovine rotavirus strains, representing three serotypes, were measured in 160 sera from cattle of different age groups. Age-specific seroprevalence analysis revealed serotype 6, represented by bovine rotavirus (BRV) NCDV, as the predominant rotavirus serotype infecting German cattle and serotype 10, represented by BRV V1005, as the least prominent. Infections with serotype 8, represented by BRV 678, occurred with intermediate frequency. Antibodies of young calves distinguished between NCDV and UK virus, two serotype 6 BRV strains differing in VP4 antigen.

摘要

在来自不同年龄组牛的160份血清中，检测了针对代表三种血清型的四种牛轮状病毒株的中和抗体滴度。年龄特异性血清流行率分析显示，以牛轮状病毒（BRV）NCDV为代表的血清型6是感染德国牛的主要轮状病毒血清型，而以BRV V1005为代表的血清型10则最不常见。以BRV 678为代表的血清型8感染发生率处于中等水平。小牛的抗体能够区分NCDV和英国病毒，这两种血清型6的BRV毒株在VP4抗原上存在差异。
