- The Chinese-like strain of the virus might have gained entry into Thailand via unknown routes as early as December 2007.
- In addition, renderingtrucks traveling from farm to farm might have encouraged widespread transmission of the disease.
- Structural differences
- in the partial S gene could help elucidate pathogenesis and antigenic structures of the recent PEDV isolates because S glycoproteins are responsible for inducing the virus neutralizing antibodies and known to be highly conserved in PEDV strains (7).
- Continuing investigation of PEDV isolates will contribute to the prevention and control of this virus.
