FIG. 2.

Individual immunogenicity of two capsid proteins: gp22 and gp29 in phages F8, LMA2, and DP1. Purified phages were injected IP 10¹⁰ pfu per mouse (N = 7) on days 0, 20, and 55. Blood sera from these mice were tested for IgG antibodies specific to structural proteins gp22 and gp29. Results are presented as OD by ELISA. Statistically significant differences (p < 0.001 Kruskal–Wallis analysis of variance) between groups are indicated with asterisks. ELISA, enzyme-linked immunosorbent assay; IgG, immunoglobulin G; IgM, immunoglobulin M; OD, optical density.
