Wolbachia-mediated antiviral protection is driven by its multimodal effects on Drosophila melanogaster metabolism

S Walsh, Tyson G Thomson, Karyn N. Johnson…·Horst Joachim Schirra

This study identifies Wolbachia's antiviral effects in Drosophila by altering host metabolism and triggering immune responses, revealing a multimodal mechanism beyond simple resource competition.

Effects of spontaneous mutations on survival and reproduction of Drosophila serrata infected with Drosophila C virus

Bonita M. Mendel, Angelique K. Asselin, Karyn N. Johnson, Katrina McGuigan

This study examines how spontaneous mutations affect survival and reproduction in Drosophila serrata infected with Drosophila C virus, finding no directional bias in mutational effects on survival but pleiotropic effects on reproductive output.
