Mouse protection induced by Pseudomonas aeruginosa PAC1R and its defective mutants, Salmonella minnesota Re-mutant and Escherichia coli O14.

Pseudomonas aeruginosa PAC1R and its defective mutants (acetone-killed bacteria), Salmonella minnesota Re mutant (acetone-killed bacteria and Re-LPS) and Escherichia coli O14 (acetone-killed bacteria and enterobacterial common antigen, ECA) were studied in a mouse active protection test. Immunized mice were challenged with wild-type P. aeruginosa strains.
