The problem of resistant Trichomonas vaginalis to antiprotozoal drugs

Abstract

This review presents recent data on the energy metabolism of Trichomonas vaginalis and ways the activation of metronidazole. The sensitivity of microorganisms to the 5-nitroimidazole by the presence of their enzyme systems, generating and transporting electrons, which can then transfer them to the nitro group of the drug. In T.vaginalis these are pyruvate ferredoxin-oxydoreductase, thioredoxin reductase and flavin reductase. The development of resistance T.vaginalis to metronidazole preparations of this multistep process, based on the gradual reduction (up to a loss) activity hydrogenosomal enzymes and / or violation of the flavindependent metabolic pathways.
