Estudio molecular de una nueva cepa de morbillivirus de cetáceo aislada de un calderon tropical

摘要

Cetacean morbillivirus (CeMV) is the most pathogenic virus in cetaceans. It includes three strains whose names refer to the species of odontocete from which it was initially isolated: Dolphin morbillivirus (DMV), Porpoise morbillivirus (PMV) and Pilot Whale morbillivirus (PWMV). The aim of this work was to complete a molecular characterization of a new strain of CeMV obtained from the brain of a short finned pilot whale stranded dead around Canary Islands with lesions compatible with morbilliviral disease. Phylogenetic trees including sequences of all the morbillivirus species have shown a higher homology with PWMV, so this strain is tentatively named “PWMV II”. Moreover, from the phylogenetic trees analysis and an exhaustive bibliographical review we propose new names for the CeMV strains:“CeMV-1” for DMV, “CeMV-2” for PMV and “CeMV-3” for PWMV.
