Six recombinant antigens of M. tuberculosis (Rv0040с, Rv1837c, Rv1860c, Rv2875, Rv2873 and Rv1636-Rv2185с) that were produced by P. pastoris were used in enzyme immunoassay of sera from patients with tuberculosis. The results of the analyses for the first four of these proteins were compared with the data for the same antigens obtained using the E. coli expression system. In all cases, the recombinant proteins produced by P. pastoris proved to be more effective as tuberculosis seromarkers; in particular, their sensitivity was by 17% on average higher. The best ELISA results were obtained with Rv2875 providing the sensitivity of 60% and specificity of 100%.

Key words:  antigens,  Pichia pastoris,  serodiagnosis,  tuberculosis.
