Toll‐deficient Drosophila is susceptible to Pythium insidiosum infection
There is a paucity of animal models of pythiosis, a life‐threatening disease of humans and animals, the
immunopathogenesis of which is poorly understood. A pythiosis model was developed by injecting Toll
(Tl)‐deficient Drosophila melanogaster flies with Pythium insidiosum zoospores. The infected Tl mutant
flies had significantly lower survival rates (73.7%) than did control flies. This study reveals the
important role of Tl pathway activation in fly immune response to pythiosis.
Key words mini‐host models, pythiosis, Toll receptors.
