V-type H+-ATPase (VA) immunolocalization in the rectum (RM) of wild-collected A. aegypti larvae reared in freshwater (FW) and septic water (Septic). VA immunostaining (green) in representative paraffin-embedded cross sections of the (a) RM and Malpighian tubules (MT) from FW-reared wild A. aegypti larvae and (b) RM of septic-reared wild A. aegypti larvae. Nuclei are labelled with DAPI (blue). (c) cross section of MT and RM from (a) with apical AeRh50 staining (red) showing colocalization of with VA in MT (merge, yellow) in FW larvae and (d) cross section of RM corresponding to (b) showing co-localization (merge, yellow) of VA with apical AeRh50 staining (red) in septic larvae. Scale bars: 50 µm. Lumen (lm); rectum (RM), Malpighian tubule (MT).
