Abstract

We investigated eleven outbreaks of naturally occurring bovine respiratory diseases in calves and adult animals in the St-Hyacinthe area of Quebec. Specific antibodies to bovine herpesvirus-1, bovine viral diarrhea virus, respiratory syncytial virus, parainfluenza type 3 virus, reovirus type 3, and serotypes 1 to 7 of bovine adenovirus were found in paired sera from diseased animals. Several bovine viruses with respiratory tropism were involved concomitantly in herds during an outbreak of bovine respiratory disease. In addition, concomitant fourfold rises of antibody titers were frequently observed to two or more viral agents in seroconverted calves (61%) or adult animals (38%). Bovine viral diarrhea virus was found to be the most frequent viral agent associated with multiple viral infection in calves only (92%).

摘要

我们调查了魁北克省圣亚森特地区小牛和成年动物中自然发生的11起牛呼吸道疾病疫情。在患病动物的配对血清中发现了针对牛疱疹病毒1型、牛病毒性腹泻病毒、呼吸道合胞病毒、副流感3型病毒、呼肠孤病毒3型以及牛腺病毒1至7型血清型的特异性抗体。在牛呼吸道疾病疫情期间,几种具有呼吸道嗜性的牛病毒在牛群中同时出现。此外,在血清转化的小牛(61%)或成年动物(38%)中,经常观察到两种或更多病毒病原体的抗体滴度同时出现四倍升高。仅在小牛中,牛病毒性腹泻病毒被发现是与多重病毒感染相关的最常见病毒病原体(92%)。
