The competition between M. rileyi and the gut-derived bacteria. A In vitro proliferation of M. rileyi and A. johnsonii after co-inoculation into the 0.5 × SMY medium at the indicated concentrations. The red arrows indicate M. rileyi blastospores, while the green arrowhead points to A. johnsonii. Scale bar = 50 μm. B The number of hyphal bodies in the hemolymph from the larvae at 12 and 24 hpi of A. johnsonii or PBS (control) was determined. The larvae pretreated with blastospores were injected with A. johnsonii at a concentration of 1 × 103, 1 × 104, or 1 × 105 cfu/μL. The statistical differences were analyzed using one-way ANOVA followed by Tukey's multiple comparison test. The different characters above the bars represent significant differences
