LYZ and bacterial infectious disease: No statistically significant correlations were observed between bacteria pathogenesis, measured as the insect mortality caused by bacterial infection 72h post-infection, and insect immune responses, measured as the number of hemocytes, lysozyme activity or phenoloxidase activity in the hemolymph of G. mellonella larvae injected with different bacteria 4h post-infection or 24h post-infection (Fig 5).
