The Chilean salmonid industry was developed by importing breeding materials, a practice still in effect due to deficits in the national supply of roe. Importation of breeding materials is often associated with the transmission of pathogens. The objectives of this study were to compare the infectious pancreatic necrosis virus (IPNV) isolates from Chile to those of European origin and to determine the diversity of the Chilean IPNV. The VP2 genes of IPNV from Chilean fish (whose eggs originated from Scotland, Iceland and Norway) were compared to isolates from fish in Norway and Ireland. The results show that the isolates are identical (97-99%) and cluster into one genogroup. Our findings support previous reports of association between the trade-in breeding materials and transmission of pathogens. Furthermore, our results demonstrate the genotypic diversity of Chilean IPNV isolates. These findings have important implications for IPNV disease diagnosis and control in Chile.
