TABLE 3.
Cross-reactivity of antibodies to UspA1 and UspA2 proteins
| Antiserum targeta | Geometric mean ELISA titerb to:
|
|
|---|---|---|
| UspA1 | UspA2 | |
| UspA1 | 740,642c | 10,748c |
| UspA2 | 19,120d | 37,615d |
a
The preparation of the sera is described in the text.
b
ELISA geometric mean titers are for total IgG and IgM antibodies in sera from 10 mice.
c
The difference in titers of the anti-UspA1 with the two purified proteins was statistically different by the Wilcoxon signed rank test (P = 0.0002).
d
The difference in titers of the anti-UspA2 with the two purified proteins was statistically different by the Wilcoxon signed rank test (P = 0.01).
