No. of Salmonella strains showing positive color reactions (including weak reactions) | 54/58 | 48/58 | 53/58 | 53/58 | 52/58 |
Sensitivity (%) | 93.1 | 82.8 | 91.4 | 91.4 | 89.7 |
No. of non-Salmonella strains showing negative color reactions | 46/49 | 45/49 | 47/49 | 45/49 | 43/49 |
Specificity (%) | 93.9 | 91.8 | 95.9 | 91.8 | 87.8 |
The data were derived from Table 1. Sensitivity is the number of Salmonella strains giving the expected color reaction divided by the total number of Salmonella strains tested. Specificity is the number of non-Salmonella strains giving a negative color reaction or failing to grow divided by the total number of non-Salmonella strains tested.
