Investigation on status of carrying virus of wild Penaeus monodon from three resources

Abstract:

In our research, we used PCR technology to examine the viral pathogen of wild Penaeus monodon from three main producing areas, including China, Thailand, and Africa in 2008. In the 210 wild Penaeus monodon broodstocks, we detected the positive result that some of them were carrying white spot syndrome virus (WSSV), infectious hypodermal and hematopoietic necrosis virus (IHHNV) or Monodon baculovirus (MBV). The results showed that the penaeid shrimps from Thailand had a highest WSSVcarrying rate of 89.8%, and those from China had a highest IHHNVcarrying rate of 8.8%. Twelve samples carrying WSSV and IHHNV (positive rate is 5.7%) were detected. These results reveal the broodstocks from China, Thailand and Africa are ubiquitously infected by WSSV and IHHNV. Meanwhile, WSSV is still a major pathogen of penaeid shrimp. Our research enhanced the understanding of the healthy condition of wild〖WTBX〗 Penaeus monodon〖WTBZ〗 broodstock from the three main producing areas, and also revealed the new pattern of WSSV infection to a certain degree.
