Engineered gut symbiont inhibits microsporidian parasite and improves honey bee survival.

ABSTRACT: Honey bees (Apis mellifera) are critical agricultural pollinators as well as model organisms for research on development, behavior, memory, and learning. The parasite Nosema ceranae, a common cause of honey bee colony collapse, has developed resistance to small-molecule therapeutics. An alternative long-term strategy to combat Nosema infection is therefore urgently needed, with synthetic biology offering a potential solution. Honey bees harbor specialized bacterial gut symbionts that are transmitted within hives. Previously, these have been engineered to inhibit ectoparasitic mites by expressing double-stranded RNA (dsRNA) targeting essential mite genes, via activation of the mite RNA interference (RNAi) pathway. In this study, we engineered a honey bee gut symbiont to
