In a murine model of skin abscesses elicited by inoculating the bacteria subcutaneously along with small (60–87 μm) dextran beads [47], IP injection of 300 μl of immune sera against 9GlcNH2-Hla 24 h and 4 h prior to infection resulted in significant reductions in the bacterial CFU/abscess produced by S. aureus strain Newman (P = 0.0011), PS80 (P = 0.0007), or LAC (P = 0.0003) when compared with animals given NRS (Fig. 5a). This evidence concerns the gene LCT and Cutaneous abscess.
