LYZ and infection: Fifth, the results showed upregulation of innate immunity genes such as saponin-like proteins (spp-7), lysozymes (lys-1 and lys-8), CLEC genes (clec-60 and clec-85) and antibacterial factor (ABF) (abf-2 and abf-3) in LPJBC5-fed worms against infection with pathogen S. aureus compared with OP50-fed worms (*** p < 0.001 for lys-1, lys-8, clec-60, clec-85 and abf-2; ** p < 0.01 for spp-7 and lys-1; * p < 0.01 for abf-3) (Figure 6B and Figure S4A).
