Table 3 Results of testing of the heterologous sera in the H5 inhibition ELISAs

From: An enzyme-linked immunosorbent assay for detection of avian influenza virus subtypes H5 and H7 antibodies

Immunisation PMV8 (n = 8) H16N3 (n = 10) H1N2 (n = 7) H9N9 (n = 7) H10N4 (n = 16) H7N1 (n = 20) H7N7 (n = 12)
H5N7ag-ELISA 6.3 (13.5) 21.5 (31.0) 19.7 (26.7) 19.1 (27.9) 13.3 (18.3) 17.6 (26.6) 42.3 (55.8)
  16.2 (28.0)  
H5N2ag-ELISA 8.4 (11.9) 11.3 (15.1) 12.9 (18.7) 7.4 (11.7) 2.8 (12.2) 3.6 (18.6) 3.0 (17.8)

2 subsequent ELISA 5.6 (12.5) 11.3 (15.1) 12.9 (18.7) 7.4 (11.7) 2.7 (11.3) 3.6 (18.6) 3.0 (17.8)
  5.7 (18.3)  
  1. Values are given as mean inhibition percentages and mean + 2 standard deviations (in brackets). Two subsequent ELISA implies that the first ELISA is done using the H5N7 antigen and then a secondary ELISA is performed with the H5N2 antigen. The minimum value for the two assays is used as the final result.
