Abstract:
Monoclonal antibodies were generated against whole cell lysate of Burkholderia pseudomallei. Two out of 6 monoclonal antibodies were found specific and exhibited high affinity against B. pseudomallei, one of which, was utilized to develop sandwich ELISA for detection of specific B. pseudomallei antigen. Immunoassays were found to be specific as no reaction was observed with closely related Burkholderia and Pseudomonas species. Blood samples from experimentally infected mice were found positive for isolation till 4 days post infection (DPI) and ELISA till 10 DPI. One out of 40 sick animal serum samples tested in Thailand was found positive by sandwich ELISA that was earlier confirmed by isolation of B. pseudomallei. The results indicate the potentiality of the assay for its applicability in specific diagnosis of septicaemic melioidosis.
