人柯萨奇病毒（humancosavirus，HCoSV）是小核糖核酸病毒科（Picornaviridae）的新成员。我们调查了从2011年8月至2012年7月的12个月期间，在亚利桑那州的进水和出水废水中HCoSV的患病率和遗传多样性。在6个（25%）进水样品和1个（4%）出水样品中鉴定出HCoSV序列，进水和出水中的最高浓度分别为3.24 × 105和1.54 × 103拷贝/升。基于其5'非翻译区对菌株进行表征，并将其分类为A和D种，表明遗传异质性HCoSV在研究区域中以明显的优势菌株时间转移而循环。
Human cosavirus (HCoSV) is a novel member of the family Picornaviridae. We investigated the prevalence and genetic diversity of HCoSV in influent and effluent wastewater in Arizona over a 12-month period, from August 2011 to July 2012. HCoSV sequences were identified in six (25 %) influent samples and one (4 %) effluent sample, with the highest concentration of 3.24 × 105 and 1.54 × 103 copies/liter in influent and effluent, respectively. The strains were characterized based on their 5’ untranslated region and classified into species A and D, demonstrating that genetically heterogeneous HCoSV were circulating with a clear temporal shift of predominant strains in the study area.
