Abstract

Objective. To express truncated TssB protein of Burkholderia mallei and to evaluate its diagnostic efficacy for serological detection of glanders among equines. Materials and Methods: In an attempt to develop recombinant protein based enzymelinked immunosorbent assay (ELISA), N-terminal200 amino acid sequences of B. mallei TssB protein-a type 6 secretory effector protein-were expressed in prokaryotic expression system. Diagnostic potential of recombinant TssB protein was evaluated in indirect ELISA using a panel of glanders positive (n = 49), negative (n = 30), and field serum samples (n = 1811). Cross-reactivity of the assay was assessed with equine disease control serum and human melioidosis positive serum. Results: In comparison to CFT, diagnostic sensitivity and specificity of ELISA were 99.7% and 100%, respectively. Conclusions: 'The indirect EUSA method using the truncated TssB offered safer and more rapid and efficient means of serodiagnosis of glanders in equines. These data highlight the use of TssB as potential diagnostic antigen for serological diagnosis of glanders.
