Lysozyme activity in the hemolymph of bacteria-infected insects.

Mean lysozyme activity in the hemolymph of G. mellonella larvae injected with different bacteria or with buffer as controls at 4h, 24h and 48h post-treatment. Bars show confidence intervals (P = 0.05). Different letters indicate significant differences in lysozyme activity across all treatments within each time point (Duncan test, Kruskall and Wallis test, P<0.05). Asterisks indicate significant differences in lysozyme activity between control larvae and bacteria-injected larvae within each time point (Dunnet test, P<0.05). Arrows indicate that the insects died.
