Abstract

Squirrelpox virus (SQPV), an unapparent infection of the Eastern grey squirrel ( Sciurus carolinensis ), is considered to be mediating the ecological replacement of the Eurasian red squirrel ( Sciurus vulgaris ) in the United Kingdom (UK) and Ireland. Evidence suggests that the Eastern grey squirrel is the natural reservoir host of SQPV and therefore there is considerable concern amongst conservationists that when translocated out of its natural range in North America, the Eastern grey squirrel could pose a similar threat to encountered indigenous squirrel populations. Serum samples collected from Eastern grey squirrels from British Columbia (BC), Canada, an introduced population derivedfromsquirrelstranslocatedatthebeginningofthe20thCentury, weresurveyedforevidence of antibodies against SQPV. None of the 130 samples tested had antibodies to the virus, contrasting with15outof19(79%)positiveserumsamplescollectedfromOntario, apopulationwithinthenat-ural range of the Eastern grey squirrel. We conclude that BC is currently free of SQPV and that to maintain the virus-free status further translocations of grey squirrels from their native range should be prevented. A comprehensive study of the founding population and comparison with the other populations in BC, including broad epidemiological surveillance for the virus is recommended as an early warning for potential incursions of the virus and the threats that this may pose.

引进加拿大东部灰松鼠:松鼠痘病毒监测和为什么无关紧要

松鼠痘病毒(SQPV)是东部灰松鼠(Sciurus carolinensis)的一种不明显的感染，被认为在英国和爱尔兰介导了欧亚红松鼠(Sciurus vulgaris)的生态替代。有证据表明，东部灰松鼠是SQPV的天然宿主，因此保护主义者非常担心，当东部灰松鼠被移出其在北美的自然范围时，可能会对遇到的本地松鼠种群构成类似的威胁。从加拿大不列颠哥伦比亚省(BC)的东部灰松鼠(20世纪初由松鼠易位而来的引进种群)采集的血清样本进行了调查，发现了抗SQPV抗体的证据。在测试的130份样本中，没有一份含有该病毒的抗体，而在东部灰松鼠的自然活动范围内，从安大略省收集的19份样本中有15份(79%)呈阳性。我们得出结论，BC目前没有SQPV，为了保持无病毒状态，应防止灰松鼠从其原生地进一步易位。建议对不列颠哥伦比亚省的发病人群进行全面研究并与其他人群进行比较，包括对该病毒进行广泛的流行病学监测，作为病毒潜在入侵及其可能造成的威胁的早期预警。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
