对1969-1972年从澳大利亚、新几内亚和诺福克岛的23个哨牛群中采集的927份血清样本进行的血清学试验证明，牛短暂热、桑福德、赤羽、达吉拉尔和罗斯河病毒广泛感染，而墨累河谷脑炎的感染则更为局部化。Kokobera和Edge Hill病毒。血清转换的时间表明，大多数感染发生在夏季和秋季。新几内亚缺乏牛抗桑福德和赤羽病毒的抗体，这与它们是最近引入澳大利亚的这一说法有关。在许多动物中，哨兵牛中的一过性发热病毒和A组和B组虫媒病毒中和抗体以及A组和B组虫媒病毒HI抗体的持续时间均少于6个月，这一发现将限制牛作为虫媒病毒感染哨兵指标的有效性。
Serological tests on 927 serum samples collected in 1969-1972 from 23 sentinel herds of cattle in Australia, New Guinea and Norfolk Island gave evidence of widespread infection with bovine ephemeral fever, Samford, Akabane, D'Aguilar and Ross River viruses and more localized infection with Murray Valley encephalitis. Kokobera and Edge Hill viruses. Timing of seroconversions suggested that most infections occurred in summer and autumn. The absence of bovine antibody to Samford and Akabane viruses in New Guinea has relevance to the suggestion that they were relatively recently introduced to Australia. Both neutralizing antibody to ephemeral fever virus and group A and B arboviruses and HI antibody to group A and B arboviruses in sentinel cattle appeared to persist for less than 6 months in many animals, a finding which will limit the usefulness of cattle as sentinel indicators of arbovirus infection.
