FIG. 1.

Vaccine efficacy of the recombinant Ag2 protein in BALB/c mice challenged by an i.p. route with 250 arthroconidia. Results are expressed as the number of CFU (mean ± standard error) in tissues at day 12 postinfection (A) and the mortality in mice at days 1 through 30 postinfection (B). The results in panel A are representative of those obtained in three separate experiments with groups of 13 or more mice immunized with the Ag2-GST protein or GST alone.
