Abstract
The risk for the emergence of novel viral zoonotic diseases in animals and humans in Uganda is high given its geographical location with high biodiversity. We aimed to identify and characterize viruses in 175 blood samples from cattle selected in Uganda using molecular approaches. We identified 8 viral species belonging to 4 families (
Flaviviridae, Peribunyaviridae, Reoviridae
and
Rhabdoviridae
) and 6 genera (
Hepacivirus, Pestivirus, Orthobunyavirus, Coltivirus, Dinovernavirus
and
Ephemerovirus
). Four viruses were novel and tetantively named as Zikole virus (Family:
Flaviviridae
), Zeboroti virus (Family:
Reoviridae
), Zebtine virus (Family:
Rhabdoviridae
) and Kokolu virus (Family:
Rhabdoviridae
). In addition, Bovine hepacivirus, Obodhiang virus,
Aedes pseudoscutellaris reovirus
and Schmallenberg virus were identified for the first time in Ugandan cattle. We report a broad range of viruses including novel ones in the blood of cattle likely as reservoir hosts for emergence of novel viruses with serious public health implications.
Highlights
Pan PCR and High Throughput Sequencing Approaches reveal novel viruses in the blood of cattle.
Identified 8 viral species belonging to 4 families:
Flaviviridae, Peribunyaviridae, Reoviridae
and
Rhabdoviridae
60% of the identified viruses were found in the Ankole cattle breed
