Vibrio and Aeromonas have distinct community architectures and biogeographies within the larval zebrafish intestine.
(A) A larval zebrafish at 5 dpf; the intestine is highlighted by phenol red dye via microgavage [27]. Scale bar: 500 μm. (B) A maximum intensity projection (MIP) of Vibrio in the larval intestine. Scale bar: 100 μm. (C) The probability density of Vibrio along the intestinal axis. From (B) and (C), we see that Vibrio is predominantly localized in the anterior bulb. (D) MIP of Aeromonas in the larval intestine. Scale bar: 100 μm. (E) The probability density of Aeromonas along the intestinal axis. (D) and (E) show that Aeromonas is predominantly localized in the midgut, with a smaller population in the anterior bulb. Underlying data for C and E are provided in S1 Data.
