Characterization of epidemic features of Norovirus and Sapovirus by comprehensive detection

进行分子生物学监测，以确定生长育肥猪中NoV和SaV的频率和年龄分布，并表征爱知县流行的菌株。在肥育猪的肠道内容物中检测到NoV和SaV。检测到的NoV毒株属于三种基因型，被称为典型的猪基因组II（GII）NoV。此外，偶尔鉴定出与人NoV GII.2显示遗传相似性的NoV。发现存在与已知猪基因型III相关的典型SaV，但在本研究中未检测到人样SaV。需要对人类和动物中的NoV和SaV进行持续监测，以了解这些病毒的演变。

A molecular biological surveillance was performed to determine the frequency and age distribution of NoV and SaV in finisher pigs and to characterize the strains prevalent in Aichi prefecture. Both NoV and SaV were detected in intestinal contents of finisher pigs. The detected NoV strains belonged to three genotypes that are known as typical porcine genogroup II (GII) NoVs. In addition, NoVs showing genetic similarity to human NoV GII.2 were occasionally identified. Typical SaVs related to known porcine genotype III were found to be present, but no human-like SaVs were detected in this study. Continuous surveillance for NoV and SaV in humans, and animals will be needed to understand the evolution of these viruses.
