We addressed the potential contribution of a small amount of IFNγ by assessing infection in larvae injected with ifng1-1 and ifng1-2 morpholinos, crfb17 morpholino (part of the signaling machinery for both IFNγ1 and IFNγ2), and a mutant in crfb17 (Aggad et al., 2010, Sieger et al., 2009). This evidence concerns the gene IFNG and infection.
