^aELISA values are expressed as OD₄₀₅.

^bImmunoblot scores are determined by subjective analysis of LAMP band intensities: 3+, strong; 2+, moderate; 1+, weak compared to negative controls (see Fig. 2).

^cPCR results are based upon presence (+) or absence (−) of predicted amplified product (374-bp fragment) by hybridization.
