Abstract

Aim. Marine mammals play the role of "sentries", standing guard over the health and functioning of marine ecosystems. The analysis of data reported in literature was carried out to understand and to evaluate a circulation of representatives of the Orthomyxoviridae and Paramyxoviridae, dangerous pathogens capable to cause morbidity and mortality in marine warm-blooded animals. Discussion. In the population of marine animals, in the available literature, no more than twenty infectious diseases were described. At the same time, according to preliminary estimates, about 15% of marine mammals die from indicated diseases. Previous studies conducted by various groups of scientists have already shown the circulation of various viral pathogens, which cause different infections in these animals. The present fact indicates the important role of marine mammals in the ecology and spreading of a number of viruses. In accordance with a literature data, representatives of Orthomixoviruses and Paramyxoviruses are among the most dangerous pathogens, which may infect this type of animals. Thus, it was suggested that seals may be infected with a wide range of influenza viruses without prior adaptation. It was emphasized that pinnipeds are one of the reservoir of a human influenza B virus in nature. Infections caused by morbilliviruses, can be the reason of epizootics in a population of seals and among the other species of marine mammals. Signs of a disease are similar to the clinic of carnivore plague. Main conclusions. The data presented in literature is extremely not enough for fully understanding a role of marine mammals as hosts or carriers of potential zoonotic pathogens, such as avian influenza virus (AIV), morbilliviruses and others. Thus, this issue requires further more detailed study.
