Mouse Response

• Host Strain: Swiss
• Vaccination Protocol: Swiss male mice were injected three times subcutaneously on days 1, 7 and 21 with the antigen. Antigen contained 10 μg of native p15 isolated from T. brucei brucei KETRI 2693, recombinant p15 purified from Ad-p15 infected HEK293 cells, partially purified subpellicular microtubules as a positive control (subpellicular fraction >30 kDa), or with PIPES buffer used to purify p15 as a negative control. Vaccinations included complete Freund’s adjuvant on first injection and incomplete Freund’s adjuvant on second and third injections. To test the protective potential of the recombinant viral vaccine, mice were injected intramuscularly (on days 1, 7 and 21) with 2×10^9 Ad-p15 virus particles or with control Ad-lacZ (Rasooly and Balaban, 2004).
• Challenge Protocol: Animals were challenged intraperitoneally on day 31 with 500 T. brucei brucei strain SB1 (Rasooly and Balaban, 2004).
• Efficacy: Vaccination of mice with p15 (native or recombinant) generated up to 100% protection from an otherwise lethal challenge of a heterologous strain of Trypanosoma brucei (Rasooly and Balaban, 2004).
