High Virulence of Wolbachia after Host Switching: When Autophagy Hurts
Figure 3
Wolbachia loads in CNS, gonads and hemocytes of Porcellio d. dilatatus and Armadillidium vulgare.
(A) Comparison between (i) P. d. dilatatus in dark grey and A. vulgare in white injected with wVulC and (ii) naturally infected A. vulgare in light grey revealed no significant differences for the Wolbachia loads in CNS cells, gonads and hemocytes (i.e immune cells), at both 30 and 60 days post-injection. (B) Comparison between (i) P. d. dilatatus in dark grey and A. vulgare in white injected with wDil and (ii) naturally infected P. d. dilatatus in dim grey revealed no significant differences for the Wolbachia loads in CNS cells at both 30 and 60 days PI. However, at 60 days post-injection, for gonads and hemocytes wDil loads were significantly higher in the native host P. d. dilatatus than in A. vulgare. A global comparison between wDil and wVulC loads showed that wVulC (A) always exhibited higher bacterial loads than wDil (B) in both host species.
