Zheng W, Teng X, Jiang T, Tang W, Jiang L, Zhu H, Yu X, Chen G, Wang J, Zhang J, Qu M, Zhang X. Genome analysis of a novel avian atadenovirus reveals a possible horizontal gene transfer. Virology 2024; 593:109999. [PMID: 38368638 DOI: 10.1016/j.virol.2024.109999] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2023] [Revised: 01/09/2024] [Accepted: 01/19/2024] [Indexed: 02/20/2024]
Abstract
We report the discovery and characterization of a novel adenovirus, Zoothera dauma adenovirus (ZdAdV), from a wild bird species, Zoothera dauma (Scaly thrush). This new atadenovirus was discovered by metagenomic sequencing without virus cultivation. Analyses of the full genome sequence revealed that this new virus is a distinct member of the genus Atadenovirus and represents a novel species. ZdAdV has a genome of 34,760 bp with 28 predicted genes and 39% GC content. ZdAdV is the first atadenovirus to contain ORF19, a gene previously found only in aviadenoviruses. Phylogenetic analysis of ORF19 suggests that it was acquired by ZdAdV through horizontal gene transfer from an aviadenovirus. By analyzing all orthologous genes of aviadenovirus, mastadenovirus, atadenovirus, and siadenovirus, we also found potential horizontal gene transfer for the E4 gene in Pigeon aviadenovirus B. Our study widens our knowledge concerning the genetic diversity and evolutionary history of atadenoviruses and their potential for cross-species transmission.

A screening of wild bird samples enhances our knowledge about the biodiversity of avian adenoviruses. Vet Res Commun 2023; 47:297-303. [PMID: 35661294 PMCID: PMC9873698 DOI: 10.1007/s11259-022-09931-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2022] [Accepted: 04/25/2022] [Indexed: 01/28/2023]
Abstract
Wild birds are threatened by anthropic effects on a global scale, and their adenoviruses might contribute to their endangerment. Thus, it is important to reveal the real biodiversity of avian adenoviruses, as, unfortunately, this research topic is far from being prioritized. The turkey hemorrhagic enteritis is an economically important disease causing high mortalities, and its causative siadenoviral agent is only distantly related to other avian siadenoviruses in phylogenetic analyses. Both to enhance our knowledge about the biodiversity of wild bird adenoviruses and to possibly trace back the origin of the turkey hemorrhagic enteritis virus, numerous Hungarian wild bird samples were screened for adenoviruses using PCR, and the detected strains were typed molecularly. The screening revealed numerous new adenovirus types, several of which represent novel adenovirus species as well, in the genera Atadenovirus, Aviadenovirus and Siadenovirus.
