Piry rhabdovirus is not transmitted from Drosophila melanogaster females to their progeny. 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.
派里弹状病毒不会从黑腹果蝇雌性个体传播给它们的后代。然而,在与另一种携带g + 遗传标记的弹状病毒西格玛病毒的混合感染中,派里病毒偶尔可能会传播给后代。因此,一种果蝇地方性病毒可以作为辅助病毒,使对脊椎动物致病的病毒实现垂直传播。
