PDEB1 is required for colonization of the proventriculus. a Prevalence and intensity of midgut infections. Teneral flies were infected at day 0 and dissected to remove the midgut 3, 7, and 14 days post infection. Infections were scored as heavy, intermediate, weak, or uninfected as described⁶⁰. P-value is shown for Fisher’s exact test, two-sided. b Prevalence and intensity of proventriculus infections. For flies with a heavy midgut infection on day 14, the proventriculus was separated from the midgut and intensity of infections was scored using the same criteria as for the midguts. P-value is shown for Fisher’s exact test, two-sided
