FIG 3.

Anti-HSV-1 IgG and IgA antibody levels and neutralizing antibody titer in ASYMP and SYMP herpes-infected individuals. Serum samples from asymptomatic and symptomatic HSV-1-infected individuals were used for an estimation of anti-HSV-1 gD antibodies by ELISA. (A) Graphs showing levels of anti-HSV-1 IgG antibody level (Left) and anti-HSV-1 IgA antibody level (Left) in serum of ASYMP and SYMP herpes-infected individuals. (A) Graph showing anti-HSV-1 neutralizing antibody titer in serum of ASYMP and SYMP herpes-infected individuals. Statistical analysis was done using Student's t test. NS, not significant.
