MUC1 and infectious otitis media: Figure 1 shows that a single intraperitoneal (i.p.)injection of 10 mg/kg AOM given to WT and MUC1.Tg mice (n= 24 and 31, respectively), followed by three cycles of 1.2% DSS in drinking water for five days, caused no mortality in WT mice whereas the mortality rate in MUC1.Tg mice was around 55% (Figure 1A).
