Porcine enteric caliciviruses (PEC) belong to the genera Norovirus and Sapovirus within the family Caliciviridae. They are enteric pathogens and are considered potential zoonotic agents. In this study, the circulation of PEC was evaluated by RT-PCR of stool samples and intestinal contents of pigs raised in Rio de Janeiro State, Brazil. Both porcine norovirus (PoNoV) and porcine sapovirus (PoSaV) were detected. The PoNoV strains were classified as genogroup II, genotypes 11, 18 and 19. The PoSaV strains were classified as genogroups III and VII, though some strains could not be classified into any established genogroup, potentially representing a new one. PEC were detected mainly in animals without clinical signs of gastroenteritis.
猪肠道杯状病毒（PEC）属于杯状病毒科诺如病毒属和沙波病毒属。它们是肠道病原体，被认为是潜在的人畜共患病原体。在本研究中，通过对巴西里约热内卢州饲养的猪的粪便样本和肠道内容物进行 RT-PCR 评估了 PEC 的流行情况。同时检测到了猪诺如病毒（PoNoV）和猪沙波病毒（PoSaV）。PoNoV 株被分类为基因 II 组、基因型 11、18 和 19。PoSaV 株被分类为基因 III 组和 VII 组，但有些株不能归入任何已建立的基因组，可能代表一个新的基因组。PEC 主要在没有胃肠炎临床症状的动物中检测到。
