Hypothesis
Can immunization with exotoxin A protect mice from Pseudomonas aeruginosa infections?
Conclusion
The study found that immunization with semi-purified exotoxin A was 93.8% effective in protecting mice from Pseudomonas aeruginosa infections.
Supporting Evidence
- 93.8% of immunized mice survived after being infected with Pseudomonas aeruginosa.
- All non-immunized mice died from bacteremia and septicemia.
- The study demonstrated the potential of exotoxin A as a vaccine candidate.
Takeaway
The researchers gave mice a vaccine made from a part of a germ that can make them sick, and it helped most of the mice stay healthy when they got infected.
Methodology
50 mice were immunized with a toxoid and then infected with Pseudomonas aeruginosa; their survival was monitored for 70 days.
Limitations
The study did not include different strains of Pseudomonas aeruginosa.
Participant Demographics
White out-bred mice were used in the study.
