Munia coronavirus HKU13 (Deltacoronavirus lonchurae) is a species of coronavirus in the genus Deltacoronavirus.[1][2]
Munia coronavirus HKU13
Munia coronavirus HKU13 (Deltacoronavirus lonchurae) is a species of coronavirus in the genus Deltacoronavirus that primarily infects birds of the genus Lonchura, commonly known as munias or mannikins.[3][4]
Classification and Discovery
Munia coronavirus HKU13 belongs to the genus Deltacoronavirus, which is one of the four genera in the family Coronaviridae.[4] The virus was first discovered by researchers from the University of Hong Kong during surveillance of coronaviruses in wild birds.[3] Its identification helped expand knowledge of coronavirus host range and evolution.
Genetic Characteristics
The virus has a positive-sense, single-stranded RNA genome typical of coronaviruses.[3] Genomic analyses show that HKU13 shares similarities with other avian deltacoronaviruses, supporting the hypothesis that birds serve as natural reservoirs for members of this genus.[4]
Importance in Research
Studying Munia coronavirus HKU13 improves understanding of interspecies transmission of coronaviruses, viral evolution, and the potential for zoonotic spillover.[3] It also serves as a model for examining coronavirus adaptation mechanisms in avian hosts.
