Order Nodamuvirales

According to the current taxonomy (ICTV 2020), the order Nodamuvirales is a single member of the class Magsaviricetes, which belongs to the Kitrinoviricota phylum from the kingdom Orthornavirae, realm Riboviria. The order Nodamuvirales currently involves 2 families, 3 genera, and 11 species. The families are Nodaviridae and Sinhaliviridae, a small family consisting of a single genus with two species of honeybee pathogens. The Nodaviridae family includes two genera, Alphanodavirus and Betanodavirus, natural hosts of which are insects and fish, respectively (Thiéry et al. 2012; Sahul Hameed et al. 2019).

Drechmeria coniospora is an agriculturally important nematode parasite that infects C. elegans through the mouth and penetrates the body by means of the proteinaceous hyphae.102C. elegans triggers an immune response against the infection through the induction of neuropeptide-like proteins (NLPs).103Nematocida parisii is a microsporidian parasite of C. elegans, and its infection did not induce basic immune-responsible genes known to be vital for other pathogenic infections but alters the components of the immune-signaling pathways (p38 MAPK and insulin signaling/DAF-2 pathways), thereby affecting animal survival.104 Recent studies have reported the interaction between C. elegans and Orsay virus, a small, positive-sense RNA virus belonging to the family Nodaviridae.105

Two studies report an enhancement effect of Wolbachia on viral infection in Drosophila species. Martinez et al. 2014 [100] tested germline transinfections with 19 Wolbachia strains in Drosophila simulans, and challenged the lines with Drosophila C virus (DCV) and Flock House virus (FHV), (+)RNA viruses from the Picornaviridae and Nodaviridae families, respectively. For DCV, 7 out of the 19 Wolbachia lines showed a significant reduction in viral titer compared to Wolbachia-negative controls, while one showed a significant increase. For FHV 5 out of the 19 lines showed a significant reduction in viral titer, while one showed a significant increase. Interestingly, the Wolbachia strain associated with increased DCV titer was not the same as the strain associated with increased FHV titer – each strain correlated with increased titers of one virus showed no significant interaction with the other.
