CD79A and infection: Env-specific IgG activity in saliva was greater than that in stool (medians, 17.84 and 0.55 ng/μg, respectively) and 2 logs greater than Env-specific IgA activity in saliva (0.08 ng/μg) but we did not find evidence of a correlation with the peak or set point VL (r = −0.26, P = 0.66; r = 0.68, P = 0.11, respectively) or the number of challenges to infection (r = −0.75, P = 0.07).
