Potential Nematode Alarm Pheromone Induces Acute Avoidance in Caenorhabditis elegans

Abstract excerpt

Abstract It is crucial for animal survival to detect dangers such as predators. A good indicator of dangers is injury of conspecifics. Here we show that fluids released from injured conspecifics invoke acute avoidance in both free-living and parasitic nematodes. Caenorhabditis elegans avoids extracts from closely related nematode species but not fruit fly larvae. The worm extracts have no impact on animal...
