However, in mixed infections with sigma, another rhabdovirus, bearing the g+ genetic marker, Piry may occasionally be transmitted to offspring. Thus, an endemic Drosophila virus can act as a helper virus enabling vertical transmission of a virus pathogenic to vertebrates. %U https://www.microbiologyresearch.org/content/journal/jgv/10.1099/0022-1317-70-1-209
