The Neotropical region harbors a considerable diversity of avian species that may play a role as both host and short-distance vectors of unknown viruses. Viral metagenomics of cloacal swabs from 50 Neotropical birds collected in French Guiana revealed the presence of four complete astrovirus genomes. They constitute an early diverging novel monophyletic clade within the Avastrovirus phylogeny, representing a putative new astrovirus species (provisionally designated as Avastrovirus 5) according to the International Committee on Taxonomy of Viruses (ICTV) classifcation criteria. Their genomic organization shares some characteristics with Avastrovirus but also with Mamastrovirus. The pan-astrovirus RT-PCR analysis of the cloacal samples of 406 wild Neotropical birds showed a community-level prevalence of 4.9% (5.1% in passerines, the highest described so far in this order of birds). By screening birds of a remote region, we expanded the known host range of astroviruses to the avian families Cardinalidae, Conopophagidae, Furnariidae, Thamnophilidae, Turdidae and Tyrannidae. Our results provide important frst insights into the unexplored viral communities, the ecology, epidemiology and features of host-pathogen interactions that shape the evolution of avastroviruses in a remote Neotropical rainforest. eng Atribución 3.0 España A novel group of avian astroviruses from Neotropical passerine birds broaden the diversity and host range of Astroviridae journal article URL https://docta.ucm.es/bitstreams/d76541ff-b1ec-4f9c-9300-6852085b30bd/download File MD5 9fe774b60179b5731dbbfc4f9c48b888 2334244 application/pdf Fernández-Correa, Izaskun et al. 2019 A novel group of avian astroviruses....pdf URL https://docta.ucm.es/bitstreams/00a10ae2-a741-49e3-aac0-fffb4f535f33/download File MD5 28ae1cab1f524e7cb40356d03c21e21c 50055 text/plain Fernández-Correa, Izaskun et al. 2019 A novel group of avian astroviruses....pdf.txt
