Ticks are ectoparasites spread worldwide and are well known as vectors of many viruses of great
importance to human and animal health. However, the viral diversity in ticks is still poorly understood,
particularly in South America. Here we characterized the viral diversity present in Rhipicephalus
microplus parasitizing cattle in the southern region of Brazil using metagenomics. Our study
revealed the presence of viruses that had not been previously described in the region, including
lihan tick virus (Phenuiviridae family) and wuhan tick virus 2 (Chuviridae family), as well as expands
the biogeography of jingmen tick virus (Flaviviridae family) in Brazil. Also, we described three novel
tymoviruses (Tymovirales order), named guarapuava tymovirus-like 1 to 3. We described the genomic
and phylogenetic characterization of these viruses. Our study sheds light on the viral diversity of
Rhipicephalus microplus in South America, and also expands the biogeography of tick viruses that were
previously described only in Asia. |
