(A to C) Median survival of vaccinated mice after intranasal infection with C. immitis. Vaccinations were adjuvant only (open symbols), 0.5 μg of rAg2/PRA (solid inverted triangle), 1.0 μg of rAg2/PRA (solid circles), 5.0 μg of rAg2/PRA (solid upright triangle), or 1.0 mg of whole killed spherules (solid squares). Each point indicates results from groups ranging from 10 to 14 animals. Each asterisk indicates a significant difference (P < 0.05) between a specific group of animals receiving rAg2/PRA as compared to a group administered the same number of arthroconidia, but which received adjuvant without rAg2/PRA. (A) BALB/c mice vaccinated subcutaneously. (B) C57BL/6 mice vaccinated subcutaneously. (C) BALB/c mice vaccinated intranasally. (D) BALB/c mice vaccinated with whole killed spherules.
