A viral metagenomics study was conducted in beef, pork, and chicken sold in supermarkets from Southern Brazil. From chicken, six distinct gyroviruses (GyV) were detected, including GyV3 and GyV6, which for the first time were detected in samples from avian species, plus a novel smacovirus species and two highly divergent circular Rep-encoding ssDNA (CRESS-DNA) viruses. From pork, genomes of numerous anelloviruses, porcine parvovirus 5 (PPV5) and 6 (PPV6), two new genomoviruses and two new CRESS-DNA viruses were found. Finally, two new CRESS-DNA genomes were recovered from beef. Although none of these viruses have history of transmission to humans, the findings reported here reveal that such agents are inevitably consumed in diets that include these types of meat.
一项病毒宏基因组学研究在巴西南部超市销售的牛肉、猪肉和鸡肉中进行。从鸡肉中检测到六种不同的回转病毒（GyV），包括 GyV3 和 GyV6，这是首次在禽类样本中检测到这些病毒，此外还有一种新型 smacovirus 物种和两种高度分化的圆形 Rep 编码 ssDNA（CRESS-DNA）病毒。从猪肉中发现了大量的圆环病毒、猪细小病毒 5（PPV5）和 6（PPV6）、两种新的基因组病毒和两种新的 CRESS-DNA 病毒。最后，从牛肉中回收了两种新的 CRESS-DNA 基因组。虽然这些病毒都没有历史上向人类传播的记录，但这里报告的发现表明，在包括这些肉类的饮食中，这些病原体不可避免地会被摄入。
