Two and three genotypes of enterovirus G (EV-G) carrying a papain-like cysteine protease (PL-CP) sequence were detected on two pig farms and classified into genotypes G1 and G10, and G1, G8, and G17, respectively, based on VP1 sequences. A G10 EV-G virus bearing a PL-CP sequence was detected for the first time. Phylogenetic analysis of the P2 and P3 regions grouped the viruses by farm with high sequence similarity. Furthermore, clear recombination break points were detected in the 2A region, suggesting that PL-CP EV-G-containing strains gained sequence diversity through recombination events among the multiple circulating EV-G genotypes on the farms.

在两个猪场中检测到带有木瓜蛋白酶样半胱氨酸蛋白酶（PL-CP）序列的肠道病毒G（EV-G）的两种和三种基因型，分别基于基因型G1和G10，G1，G8和G17在VP1序列上。首次检测到带有PL-CP序列的G10 EV-G病毒。对P2和P3区域的系统发育分析按具有高度序列相似性的场对病毒进行了分组。此外，在2A区域检测到清晰的重组断裂点，这表明包含PL-CP EV-G的菌株通过农场中多个循环EV-G基因型之间的重组事件获得了序列多样性。
