Kinetics of humoral response and mechanism of the protection in mice vaccinated with slime-extract from Pseudomonas aeruginosa.

The in vivo experiments on the immunity of mice to P. aeruginosa showed that the vaccination with slime-extract or transfer of immune anti-slime serum enhances the resistance of mice to these organisms. Immunity against P. aeruginosa appears early after vaccination, is long-lasting and very effective since the challenging organisms are eliminated from the mouse spleens within 4 days.
