Discovery of fur seal feces-associated circular DNA virus in swine feces inJapan

摘要

Fur seal feces-associated circular ssDNA virus (FSfaCV) was discovered in a pig for the first time in Japan using a next-generation sequencer with duplex-specific nuclease. Full genome of the virus showed approximately 92% similarity to FSfaCVs from New Zealand fur seals. Furthermore, we investigated the prevalence of the ssDNA virus in 85 piglets in Japan, and 65 piglets were positive (76%) for the virus.
