Species rarefaction analysis of sample sequences and differences in bacterial community structures among different groups. Species rank-abundance curve (A) and rarefaction curve (B) analysis of sample sequences. (C) Principal coordinate analysis (PCoA) of bacterial community structures of the different groups. (D) UPGMA tree analysis of evolving samples. Each symbol represents one sample of different dilutions of P. aeruginosa. Wa, Ya, Yb, Yc, Yd, and Ye represent housefly larvae samples fed diets with sterile water, P. aeruginosa stock solution, and the stock solution diluted 10², 10⁴, 10⁶, and 10⁸ fold, respectively.
