Fig. 3

Illustration summarizing the Eagle effect on the endosymbiont Wolbachia in its worm host. The illustration depicts the worm and Wolbachia response to doxycycline, tetracycline and rifampicin. With doxycycline and tetracycline treatment worms become moribund at high concentration despite the high numbers of Wolbachia. Relative inhibition of worm motility is in blue (top), and relative changes in Wolbachia titers are in red (bottom). Worm motility is represented by the drawing of the worm: darker blue worms indicate more motility, and lighter blue worms indicate inhibited motility. Wolbachia titers are represented by red dots within the circle and are proportional to the Wolbachia titers normalized to controls
