Fold increase of SibaCec in the salivary glands of insects after oral infection with E.coli at different time course. Expression levels in the salivary glands of bacteria-immunized insects were calculated relative to the level of SibaCec in corresponding naive insects, which was arbitrarily defined as 1. *p < 0.05, **p < 0.01, significantly different compared to the control that received the sucrose solution without E.coli
