Porcine astrovirus type 3 in central nervous system of swine with polioencephalomyelitis

Abstract

Using next-generation sequencing, we identified and geneti­cally characterized a porcine astrovirus type 3 strain found in tissues from the central nervous system of 1 piglet and 3 sows with neurologic signs and nonsuppurative polioencephalomyelitis. Further studies are needed to understand the potential for cross-species transmission and clinical impact.
