Abstract

ABSTRACT Reindeer herding is of great importance for the indigenous people of the Fennoscandia peninsula and northern Russia. There are also free-ranging feral populations of reindeer in Finland, Iceland, Norway and Russian Federation. The genus Pestivirus contains several viral species that infect ungulates and often show capacity to transmit between different host species. Sera from 520 Eurasian tundra reindeer (Rangifer tarandus tarandus) from Finland, Sweden, Norway, Iceland and Russian Federation were analysed and the prevalence of pestivirus-specific antibodies was determined. Seropositivity proportion was 48.5% for Sweden and 41.2% for Norway, but only 1.6% for Iceland and 2.5% for Finland. All Russian reindeer investigated were seronegative. Pan-pestivirus RT-PCR of seronegative animals (n = 156) from seropositive herds confirmed their negative status. These results indicate unexpectedly non-uniform circulation of an as yet uncharacterised pestivirus in Eurasian reindeer populations. The high seroprevalence in some regions warrants further studies of pestivirus infection dynamics, effects on reindeer health and population dynamics.

芬兰、瑞典、挪威、冰岛和俄罗斯联邦欧亚苔原驯鹿的鼠疫病毒血清流行率

驯鹿放牧对芬诺斯坎迪亚半岛和俄罗斯北部的土著居民来说是非常重要的。在芬兰、冰岛、挪威和俄罗斯联邦也有自由放养的野生驯鹿。鼠疫病毒属包含几种感染有蹄类动物的病毒，并且经常显示出在不同宿主物种之间传播的能力。分析了来自芬兰、瑞典、挪威、冰岛和俄罗斯联邦的520只欧亚苔原驯鹿(Rangifer tarandus tarandus)的血清，并测定了鼠疫病毒特异性抗体的流行率。瑞典和挪威的血清阳性比例分别为48.5%和41.2%，冰岛和芬兰的血清阳性比例分别为1.6%和2.5%。所有调查的俄罗斯驯鹿血清均呈阴性。血清阳性畜群中血清阴性动物(n = 156)的泛鼠疫病毒RT-PCR结果证实其为阴性。这些结果表明，在欧亚驯鹿种群中，一种尚未表征的鼠疫病毒的传播出乎意料地不均匀。某些地区的高血清流行率值得进一步研究鼠疫病毒感染动态、对驯鹿健康的影响和种群动态。

期刊介绍： Infection Ecology & Epidemiology aims to stimulate inter-disciplinary collaborations dealing with a range of subjects, from the plethora of zoonotic infections in humans, over diseases with implication in wildlife ecology, to advanced virology and bacteriology. The journal specifically welcomes papers from studies where researchers from multiple medical and ecological disciplines are collaborating so as to increase our knowledge of the emergence, spread and effect of new and re-emerged infectious diseases in humans, domestic animals and wildlife. Main areas of interest include, but are not limited to: 1.Zoonotic microbioorganisms 2.Vector borne infections 3.Gastrointestinal pathogens 4.Antimicrobial resistance 5.Zoonotic microbioorganisms in changing environment
