Description
Abstract
Los nodavirus afectan a gran número de especies de peces, silvestres y cultivadas. En silvestres se ha aislado en diversas especies, pero nunca se había asociado con procesos clínicos en el litoral de Murcia. En otoño de 2017, se detectaron diversos ejemplares de meros (Epinephelus marginatus y E. costae) en la Reserva
de Cabo de Palos con sintomatología clínica compatible con nodavirus. La infección por nodavirus fue confirmada mediante RT-PCR
en tiempo real y su posterior genotipado (tipo RGNNV). Este hallazgo constituye la primera evidencia regional de infección clínica
por nodavirus en peces silvestres, con la relevancia añadida de
que la especie afectada es la especie emblemática de la Reserva
Marina de Cabo de Palos, el mero.
Abstract: Nodaviruses affect a large number of fish species, wild and farmed. In the wild it has been isolated in various species, but it had never been associated with clinical processes on the coast of Murcia. In autumn 2017, several specimens of groupers (Epinephelus marginatus and E. costae) were detected in the Cabo de Palos Reserve with clinical symptoms compatible with nodavirus. The infection by nodavirus was confirmed by real time RT-PCR and its subsequent genotyping (RGNNV type). This finding constitutes the first regional evidence of clinical infection by nodavirus in wild fish, with the added relevance that the affected specie, the grouper, is the emblematic specie of the Cabo de Palos Marine Reserve.
