Characterization and localization of Opisthorchis viverrini fructose-1,6-bisphosphate aldolase.

Opisthorchis viverrini (Ov) infection is a long-time public health problem in Thailand that can lead to bile duct cancer, cholangiocarcinoma (CCA). Characterization of the Ov proteins at a molecular level will increase our knowledge of host-parasite interaction that can be applied to new drug, vaccine, or immunodiagnostic development. In this study, an important enzyme in the Ov glycolytic pathway, fructose-1,6-bisphosphate aldolase (FBPA), that had been obtained from a previous study was characterized and immunolocalized.
