Identification of a novel astrovirus in domestic sheep in Hungary.
The family Astroviridae consists of two genera, Avastrovirus and Mamastrovirus, whose members are associated with gastroenteritis in avian and mammalian hosts, respectively. We serendipitously identified a novel ovine astrovirus in a fecal specimen from a domestic sheep (Ovis aries) in Hungary by viral metagenomic analysis. Sequencing of the fragment indicated that it was an ORF1b/ORF2/3'UTR sequence, and it has been submitted to the GenBank database as ovine astrovirus type 2 (OAstV-2/Hungary/2009) with accession number JN592482. The unique sequence characteristics and the phylogenetic position of OAstV-2 suggest that genetically divergent lineages of astroviruses exist in sheep.
