Absence of epizootic hematopoietic necrosis virus (EHNV) in diseased rainbow trout (Oncorhynchus mykiss) from fish farms in the Peruvian highlands
Descripción del Articulo
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 An...

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 identification by Gram stain and bacterial biochemistry. The EHNv DNA was not detected indicating that the prevalence of the virus is less than 5% or it is not present in the sampled fish farms. Yersinia ruckeri and Aeromonas spp were isolated in all the samples, indicating that the cause of the disease and mortality present in the fish farms was due to the infection with these bacteria. El objetivo del presente trabajo fue monitorear la detección del virus Necrosis Hematopoyética Epizoótica (EHNv) en truchas (Oncorhynchus mykiss) de piscigranjas de la Sierra del Perú. Se tomaron muestras de 111 peces enfermos (hígado, bazo, riñón anterior) de piscigranjas de las regiones de Áncash, Junín y Huancavelica, Perú. Las muestras de tejidos fueron procesados de inmediato para el aislamiento bacteriano y otro grupo de muestras fueron conservadas a -196 °C para el PCR. El ADN de cada tejido fue extraído mediante el método del Trizol y luego purificado con membranas de sílica (PureLinkGenomic DNA kit). El PCR se realizó utilizando los cebadores MCP-1 específicos para el EHNv siguiendo la metodología propuesta por la OIE y con el kit comercial VetPCRTM EHNV Detection para su confirmación. El aislamiento bacteriano se realizó con el sembrado en agar TSA y Anacker-Ordal (agar citófaga) de cada tejido y la identificación mediante tinción Gram y bioquímica bacteriana. No se detectó el ADN del EHNv en las muestras indicando que la prevalencia del virus es menor al 5% o no está presente en las piscigranjas muestreadas. Se aisló Yersinia ruckeri y Aeromonas spp en todas las muestras, indicando que la causa de la enfermedad y mortalidad presente en las piscigranjas se debían a la infección con estas bacterias. |
