2. Classification of CQV:
The order Bunyavirales is found to have more than 350 viruses
with tripartite, negative-sense, single-stranded RNA (ssRNA) genomes,
belonging to 9 viral families. The members of the Feraviridae,
Phenuiviridae, Fimoviridae, Nairoviridae, Peribunyaviridae,
Tospoviridae, Jonviridae and Phasmaviridae families are carried
and transmitted through arthropods, while the viruses of theHantaviridae family are carried by rodents and are transmitted
through the communication of aerosolized excreta(Elliott, 2013; Whitmer
et al., 2018). Fimoviridae and Tospoviridae family viruses
infect plants, while the viruses of family Nairoviridae ,Peribunyaviridae , and Phenuiviridae can transmit the
disease to vertebrates. Genus Orthobunyavirus is the largest
genus in the Peribunyaviridae family that contains more than 170
viruses. Orthobunyaviruses are categorized into 49 species and 19
serogroup complexes (Briese et al., 2013; Maes et al., 2018),consisting
of extremely diverse arboviruses (Nguyen et al., 2013). Simbu serogroup
has been the largest of these with 25 viruses isolated till date (Ladner
et al., 2014) and with seven species complexes such asAkabane,
Simbu, Oropouche, Shuni, Sathuperi, Shamonda, andManzanilla (Zhang
et al., 2015; Saeed et al., 2001). CQV is one of the members of theManzanilla species complex belonging to the Simbu serogroup
(Figure 1).
