Immunoprophylactic treatment of PCM.

<p>Gene immunization was initiated 30 days before fungal challenge. CFUs are from lungs of BALB/c mice infected intratracheally with 3×10⁵ yeast cells and subjected to immunization with vectors containing P10 (pP10) and/or IL-12 (pIL-12) DNA insert. Control mice were inoculated with PBS or with vectors without insert. Mice were sacrificed 30 (▪) and 60 (□) days after infection. Each bar represents the average counts and standard deviations of CFUs in lungs from 10 animals in each group. Experiments were carried out in triplicate with similar results. <b>**</b><i>p</i>≤0.0001, comparing vector with and without insert; ^##<i>p</i>≤0.0001, .comparing untreated and other groups.
