| Outline of Final Research Achievements |
An effective vaccine against Pseudomonas aeruginosa would be hugely beneficial to people who are susceptible to the serious infections caused by it. Vaccination against PcrV of the P. aeruginosa type III secretion system is a potential prophylactic strategy for improving the incidence and poor prognosis of P. aeruginosa pneumonia. Here, the effect of nasal PcrV adjuvanted with CpG oligodeoxynucleotide (CpG) was investigated in an mouse model of P. aeruginosa pneumonia. In vaccinated mice, the significant increase in PcrV-specific titers was detected. Vaccinated mice with nasal PcrV-CpG vaccine survived from a lethal P. aeruginosa pneumonia. Overall, our data show that the nasal PcrV-CpG vaccine has potential efficacy for clinical application against P. aeruginosa pneumonia.
