isolation and differentiation of various species of mycobacteria are predominantly based on conventional, cultural and biochemical tests. among the non-tuberculous mycobacteria, these tests are unable to differentiate m. scrofulaceum from m. avium-intracellulare (mai) because of their identical biochemical characteristics. for this reason, one hundred mycobacterial strains suspected to be m. sc...

In this study, we have identified a secreted 13 kDa lectin from Mtb (Mtb, Mycobacterium tuberculosis; sMTL-13) by homology search of a non-redundant lectin database. Bioinformatic analysis revealed that sMTL-13 belongs to the ricin-type beta-trefoil family of proteins containing a Sec-type signal peptide present in Mtb complex species, but not in non-tuberculous mycobacteria. Following heterolo...
