TABLE 1.
Quantitation of phagocytic uptake by PMNs of P. aeruginosa FD 4 cells exposed to antisera from immunized mice
| Test serum | No. of bacteria/PMN (mean ± SD) | Opsonic ratioa (P) |
|---|---|---|
| Vector control | 9.48 ± 7.46 | |
| DNA-protein F | 12.69 ± 9.31 | 1.34 (<0.00001) |
| NMSb | 9.21 ± 8.32 | |
| Protein F | 14.41 ± 11.56 | 1.56 (<0.00001) |
a
Opsonic ratio is the mean number of bacteria associated with test sera per PMN divided by the mean number of bacteria associated with the appropriate control sera per PMN. P values were determined by unpaired two-tailed Student t test.
b
NMS, pooled normal mouse sera collected from nonimmunized, specific-pathogen (P. aeruginosa)-free mice.
