The objective of the present study was to monitor the detection of the Epizootic Hematopoietic Necrosis virus (EHNv) in trouts (Oncorhynchus mykiss) in fish farms of the highlands of Peru. Samples were taken from 111 diseased fish (liver, spleen, anterior kidney) from fish farms in the regions of Ancash, Junín and Huancavelica, Peru. The tissue samples were processed immediately for bacterial isolation and another group of samples were stored at -196 °C for PCR. The DNA of each tissue was extracted by the Trizol method and then purified with silica membranes (PureLink Genomic DNA kit). The PCR was performed using the MCP-1 primers specific for the EHNv, following the methodology proposed by the OIE and with the commercial kit VetPCRTM EHNV Detection for confirmation. Bacterial isolation was carried out by culturing on TSA and Anacker- Ordal agar (Cytophaga agar) of each tissue, and the...
