丁型冠狀病毒屬(學名:Deltacoronavirus、δ-CoV)是冠狀病毒亞科的四個屬之一,為具有包膜的正鏈RNA病毒。有別於甲型冠狀病毒屬與乙型冠狀病毒屬僅感染哺乳動物,本屬與丙型冠狀病毒屬主要感染鳥類,兩屬的共祖可能皆是感染鳥類的病毒[1]。本屬也包含一些能感染哺乳動物的病毒,如猪丁型冠状病毒(PDCoV)、石虎冠狀病毒(Asian leopard cat CoV)與鼬獾冠狀病毒(Chinese ferret badger CoV),其中前者為造成豬腹瀉的主要病毒之一[2]。
丁型冠狀病毒的基因組約長25-26kb,是冠狀病毒中基因組最小者[3]。
丁型冠狀病毒屬包含以下亞屬與種[4]:
- Andecovirus
- Buldecovirus
- Herdecovirus
- Moordecovirus
- 紅冠水雞冠狀病毒HKU21(CMCoV HKU21)
- 尚未歸類
- 鵲鴝冠狀病毒HKU18(MRCoV HKU18)
- 隼冠狀病毒HKU27(FalCoV UAE-HKU27)
- 翎頜鴇冠狀病毒HKU28(HouCoV UAE-HKU28)
- 鴿冠狀病毒HKU29(PiCoV UAE-HKU29)
