Transcript abundances of Lpp [apolipophorin 1,2 (AAEL009955)] (lpp; Left) and the LppR (AAEL018219) (lppR; Right) in pelts from gnotobiotic larvae inoculated with wild-type E. coli (GN), GN treated with PX-478 (12 h posthatching), gnotobiotic larvae inoculated with ΔcydB-ΔcydD::kan E. coli (Δcyd), or Δcyd treated with FG-4592 (12 h posthatching). Samples were collected at 12 h posthatching (GN, Δcyd) or 12 h posttreatment (GN + PX-478, Δcyd + FG-4592), with values expressed in transcripts per kilobase million (TPM). In each graph, bars with different letters significantly differ from one another (ANOVA followed by a post hoc Tukey–Kramer honest significant difference test, P < 0.05).
