In addition to the Gp60 and Cp23 antigens, a significant association with protection from cryptosporidiosis was observed for antibodies against the Gp900 mucin (cgd7_4020), the potential mucin CpMuc8 (cgd8_700), the putative metal ion transporter CpCorA (cgd2_1520), a small membrane protein (Chro.30111) (Figure 7D), the Gp900 mucin (cgd7_4020) (Figure 7E), the putative metal ion transporter CpCorA (cgd2_1520)(Figure 7F), the potential mucin CpMuc8 (cgd8_700)(Figure 7G), and the coiled coil domain protein CpCCDC (cgd8_830) (additional RF comparisons are shown in Supplemental Figure 8). The gene discussed is CEMP1; the disease is cryptosporidiosis.
