TABLE 3.
Quantitation of P. aeruginosa present in the lungs of immunized mice following challenge with FD 4 P. aeruginosa in a chronic pulmonary infection model
| Immunization group | No. of mice with lungs yielding no growth/total no. of mice (%)a | No. of mice with lungs yielding >5 × 103 CFU/total no. of mice (%)b |
|---|---|---|
| Vector control | 12/42 (28.6) | 29/42 (69.0) |
| DNA-protein F | 22/44 (50.0) | 18/44 (40.9) |
a
P value was 0.035 as determined by Fisher's exact test.
b
The P value was 0.008 as determined by Fisher's exact test.
