Abstract
Background: Tamdy Virus (TAMV) is a pathogenic nairovirus widely distributed in central Asia and northwestern China. However, the host range of TAMV remains unclear, which limits our understanding the transmission cycle and cross-species patterns of this virus. Materials and Methods: A total of 160 serum samples were collected from livestock animals of camels, cattle, and sheep in Xinjiang, China between 2018 and 2021. An indirect immunofluorescence assay for TAMV were developed in this study, and have been employed to test TAMV-specific antibodies in these serum samples. Results: TAMV IgG antibody was detectable in camel sera collected from Urumqi in 2018 (6/17, 35%) and also from the Alertai Region in 2021 (1/8, 12.5%). Conclusion: The serological results in this study provide the first evidence that TAMV is able to infect camels and that the pathogen is circulating in different regions of Xinjiang. These findings highlight the need to further increase clinical and epidemiological surveillance of TAMV in humans and livestock in northwestern China.
