In this study, bovine enteric caliciviruses (BECs) were detected in 49.4% of a total of 253 stool specimens for diarrheic calves collected from 42 industrial dairy farms from March 2010 to February 2012. Genogroup III norovirus (NoVsGIII) were more prevalent (39.5%) than neboviruses (NBs) (15%), and coinfections were observed in 5.1% of the samples tested. Sequence analysis of the partial polymerase gene from 13 NoVsGIII samples indicated the circulation of both genotype 1 and genotype 2 strains. Among the six NB strains sequenced, five were related to the Bo/Nebraska/80/US strain, while one was related to the Bo/Newbury1/76/UK strain.
在本研究中，从2010年3月至2012年2月期间，从42个工业化奶牛场收集的253份腹泻犊牛粪便样本中，49.4%检测到牛肠道杯状病毒（BECs）。基因组III型诺如病毒（NoVsGIII）（39.5%）比neboviruses（NBs）（15%）更普遍，并且在5.1%的检测样本中观察到混合感染。对13个NoVsGIII样本的部分聚合酶基因进行序列分析表明，基因型1和基因型2毒株均有传播。在测序的6个NB毒株中，5个与Bo/Nebraska/80/US毒株相关，而1个与Bo/Newbury1/76/UK毒株相关。
