In 2015, a novel equine parvovirus, equine parvovirus‐cerebrospinal fluid (EqPV‐CSF), was identified from cerebrospinal fluid of a horse with neurological signs and lymphocytosis in USA. In our study, an EqPV‐CSF‐like virus was detected from 15 serum samples of 65 imported thoroughbred horses during custom quarantine in north Xinjiang province, China. Further field investigation in several major horse‐producing areas in Xinjiang using specific PCR showed that this virus was detected mainly in thoroughbred horses (39/154 positive) previously imported, not in local breeds (0/127 positive). Phylogenetic analysis based on NS1 gene showed the virus was grouped together with EqPV‐CSF in genus Copiparvovirus. The study presents valuable information showing that EqPV‐CSF‐like virus was likely exotic and introduced into Xinjiang through international trade of horses.
