TABLE 3.
Reactivity of viremic sera in the in-house IgM ELISA
| Panel | Virus serotypea | No. of serum samples | In-house ELISA mean A450 (range)b |
|---|---|---|---|
| 1 | DEN-3 | 7 | 2.45 (1.47-5.00) |
| 2 | DEN-2 | 2 | 1.07 (0.92-1.22) |
| DEN-3 | 9 | 2.27 (0.83-5.00) |
a
Virus serotype was identified by RT-PCR (29). Infectious virus could be isolated from both DEN-2 virus- and 12 DEN-3 virus-infected sera.
b
The values in this column indicate the reactivity of anti-DEN virus IgM antibodies to rEDIII-T protein in terms of mean A450; the values in parentheses indicate the range of observed absorbance values.
