   Abstract

Five ELISAs developed to detect antibodies to different B. pseudomallei antigen preparations were evaluated as diagnostic tests for melioidosis in northeast Thailand. The highest diagnostic indices were observed for an affinity-purified antigen (sensitivity 82%, specificity 72%) and crude B. pseudomallei antigen (sensitivity 81%, specificity 70%), an improvement over the IHA (sensitivity 73%, specificity 64%).
