Key result
Viral metagenomics identifies multiple novel viruses in black-necked crane fecal samples.
Why the study?
There is little research on viral diseases of the black-necked crane, the only species living in the plateau.
Observational
No
The study identified multiple novel viruses in the fecal samples of black-necked cranes, providing valuable information on their viral community composition.
Viral discovery in endangered cranes leaves open zoonotic surveillance needs; hypothesis-generating for wildlife and cross-species research.
The black-necked crane is the only species that lives in the plateau. At present, there is little re-search on viral diseases of the black-necked crane. In this study, a virus metagenomics approach was employed to investigate the viral composition of black-necked cranes in Saga County, Shi-gatse City, Tibet, China. The identified virus families carried by black-necked cranes mainly in-clude Genomoviridae, Parvoviridae, and Picornaviridae. Among them, one picornavirus genome is characterized as a novel species in the genus Grusopivirus of the family Picornaviridae, four new parvoviruses genome were obtained and classified into four different novel species within the genus Chaphamaparvovirus of the subfamily Hamaparvovirinae, and four novel genomoviruses ge-nome were also acquired and identified as members of three different species including Ge-mykroznavirus haeme1, Gemycircularvirus ptero6, and Gemycircularvirus ptero10. All of these viruses were firstly detected in fecal samples of black-necked cranes. This study provides valuable in-formation for understanding the viral community composition in the digestive tract of black-necked cranes in Tibet and for monitoring, preventing, and treating black-necked cranes viral diseases.

Zhao et al. (2023) conducted an observational in Viral composition in black-necked cranes. Viral metagenomics approach was evaluated on Viral composition and identification of novel viruses. A viral metagenomics approach identified multiple novel viruses in black-necked crane fecal samples, including new species in the Genomoviridae, Parvoviridae, and Picornaviridae families.
