Detection of tilapia lake virus (TiLV) by seminested RT-PCR in farmed tilapias from two regions of Peru
Descripción del Articulo
The production of tilapia (Oreochromis sp) is being affected by outbreaks of lake tilapia virus (TiLV) with high mortality in the main breeding regions in Peru. The aim of this study was to determine the presence of TiLV in two tilapia fish farms in Piura and San Martín, which presented mortalities...

The aim of this study was to determine the presence of TiLV in two tilapia fish farms in Piura and San Martín, which presented mortalities greater than 60%. Samples (liver and brain) were taken from 70 fish from different stages of culture that showed lethargy, loss of appetite, eye lesions and skin erosions. The detection and confirmation of TiLV was determined by semi-nested RT-PCR and subsequent sequencing of the amplified product of segment 3 of the virus. Products of the expected weight (250 bp) corresponding to samples from the two production centres were found. The phylogenetic analysis showed a high homology among the isolates and an identity greater than 90% with the Israeli reference strain (KU751816.1).El cultivo de la tilapia (Oreochromis sp) se encuentra afectada por brotes con alta mortalidad del virus de la tilapia del lago (TiLV) en las principales regiones de crianza en el Perú. El presente estudio tuvo como objetivo determinar la presencia del TiLV en dos centros piscícolas de tilapia en Piura y San Martín, que presentaron mortalidades superiores al 60%. Se tomaron muestras (hígado y cerebro) de 70 peces de diferentes fases de cultivo que mostraron letargia, pérdida del apetito, lesiones oculares y erosiones de la piel.
