CLU and infection: Before infection (21d), all groups were positively associated with lipocalin/cytosolic fatty-acid binding domain-containing protein (A0A060ZEQ3), serpin domain-containing protein (A0A060WX77), transcobalamin-like C-terminal domain-containing protein (A0A060XH24), clusterin (A0A060W8D1) and somatomedin B (SMB) domain-containing protein (A0A060Y4C1) (Figure 8).
