ATAD1 and infection: Lower-density infections remained associated with increased IgG levels to CyRPA (P = 0.012) and GAMA (P = 0.007), and higher-density infections remained associated with increased IgG levels to CyRPA (P<0.001), GAMA (P = 0.005), P12 (P = 0.017), P41 (P = 0.031), MSP1 (P = 0.014), and RIPR (P = 0.012).
