A fox circovirus was identified in serum samples from foxes with unexplained neurologic signs by using viral metagenomics. Fox circovirus nucleic acid was localized in histological lesions of the cerebrum by in situ hybridization. Viruses from the family Circoviridae may have neurologic tropism more commonly than previously anticipated.
Circoviruses (family Circoviridae) are nonenveloped, single-stranded, circular DNA (≈2 kb) viruses (1). Two genera, Circovirus and Gyrovirus, are recognized, and an additional genus, Cyclovirus, has been proposed (1,2). Circoviruses have an ambisense genome organization with 2 major inversely arranged open reading frames encoding the rolling circle replication initiator protein gene (Rep) and a capsid protein gene (Cap) (1). A conserved stem–loop structure, required for viral replication, is located between the 5′ ends of the 2 main open reading frames. Circoviruses are thought to exhibit host species specificity and have been detected in various species, including birds, pigs, and dogs (1,3,4). These viruses have been associated with a variety of diseases, including respiratory and enteric disease, dermatitis, and reproductive problems (1,35). Recently, many small circular DNA genomes have been described from different hosts by using different methods, including high-throughput sequencing (6). Here we describe the identification, characterization, and prevalence of a newly discovered fox circovirus that was present in serum and brain samples from foxes with unexplained meningoencephalitis in the United Kingdom.
