For example, Fuji et al. [39] performed a joint serological surveillance of six infectious diseases using eight different recombinant antigens (Entamoeba histolytica [C-IgL], Leishmania donovani [KRP42], Toxoplasma gondii [SAG1], Wuchereria bancrofti [SXP1], HIV [gag, gp120, and gp41], and Vibrio cholerae [cholera toxin]). The gene discussed is ITIH4; the disease is infectious disease.
