title: Detection of paramyxoviruses in Magellanic penguins (Spheniscus magellanicus) on the Brazilian tropical coast.
abstract: Aquatic migratory birds are a major vectors by which influenza viruses and paramyxoviruses are spread in nature. Magellanic penguins (Spheniscus magellanicus) are usually present on the southern shores of South America and can swim as far as the southern coast of Brazil in winter. In 2008, however, several Magellanic penguins were observed on the northeastern coast of Brazil. Paramyxoviruses were isolated from Magellanic penguins on the Espírito Santo state coast, approximately 4000 km from their breeding colonies, although influenza viruses were not detected. Among the paramyxoviruses, five Avulavirus isolates belonging to serotype APMV-2 and the serotype APMV-10, which was proposed by Miller et al. (2010), were identified. These results highlight the risks associated with the spread of paramyxoviruses between natural to non-natural habitats by birds exhibiting unusual migration patterns, and they document for the first time the presence of the APMV-2 and APMV-10 serotypes on penguins in Brazil. The local avifauna may become infected with these viruses through close contact between migratory and resident birds. Continued surveillance of virus incidence in these migratory populations of penguins is necessary to detect and prevent the potential risks associated with these unusual migration patterns.
