Bats serve as reservoirs for many emerging viruses. Cressdnaviruses can infect a wide range of animals, including agricultural species, such as pigs, in which porcine circoviruses cause severe gastroenteritis. New cressdnaviruses have also attracted considerable attention recently, due to their involvement with infectious diseases. However, little is known about their host range and many cressdnaviruses remain poorly characterized. We identified and characterized 11 contigs consisting of previously unknown cressdnaviruses from a rectal swab sample of a Cynopterus bat collected in Yunnan Province, China, in 2011. Full genomes of two cressdnaviruses (OQ267680, 2069 nt; OQ351951, 2382 nt), and a nearly complete genome for a third (OQ267683, 2361 nt) were obtained. Phylogenetic analyses and the characteristics of these viral genomes suggest a high degree of ssDNA virus diversity. These results shed light on cressdnavirus diversity and the probable role of Cynopterus bats as their hosts.
