This present study is the first case of a ( ) infection reported in ( ) in China. This study aimed to identify the nematode species and explore the genetic evolution of worms infecting ( ). Clinical examination revealed several milky white parasites in the stomach and intestinal tract. Polymerase chain reaction and partial 18S gene sequencing analyses identified these worms to be (SD isolates). Further phylogenetic analyses revealed that they shared the highest genetic identity (99.9%) with a isolate (EU004820.1) from Germany. Our study is the first report on the identification and characterization of infecting in China, based on clinical findings and molecular diagnosis. Therefore, our study provides novel insights for the diagnosis of infections and the prevention of nematode transmission in wild and domestic animals.
