Fig 5. Proventricular blockage causes greater esophageal distension in O. montana than in X. cheopis.

Fig 5

(A-D) Representative images of foreguts from dissected uninfected and blocked O. montana and X. cheopis. Dashed red lines indicate the location of esophageal (E) and proventricular (PV) measurements used to calculate the E:PV ratio of uninfected fleas (open symbols; n = 20) and blocked fleas (closed symbols; n = 10 to 15) in (E); the mean and SD are indicated. *P < 0.05; **P < 0.01, ***P < 0.0001 by one-way ANOVA and Tukey’s multiple comparison test. Scale bars = 100 μm.
