Vertical Transmission of the Piry Rhabdovirus by Sigma Virus-Infected Drosophila melanogaster Females

Annie Ohanessian

Laboratoire de Génétique des Virus, CNRS, 91198 Gif sur Yvette Cédex, France

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.

Keywords: Piry virus, sigma virus, vertical transmission
