Abstract:

Circoviruses consist of highly prevalent and genetically diverse porcine and avian pathogens. The genomes of cycloviruses, a proposed new genus in the family Circoviridae, were recently identified in human and chimpanzee faeces. Here, six cyclovirus and four circovirus genomes from the tissues of chickens, goats, cows, and a bat were amplified and sequenced using rolling-circle amplification and inverse PCR. A goat cyclovirus was nearly identical to a cyclovirus from a cow. USA beef contained circoviruses with>99% similarity to porcine circovirus 2b. Circoviruses in chicken were related to those of pigeons. The close genetic similarity of a subset of cycloviruses and circoviruses replicating in distinct animal species may reflect recent cross-species transmissions. Further studies will be required to determine the impact of these highly prevalent infections on the health of farm animals.
