Blastocystis is a stramenopile or chromist, nonmobile pleomorphic. Nineteen subtypes of this organism (ST1-ST19) have been identified worldwide. This microorganism has an intermediate anaerobic metabolism. An interesting aspect of the biochemistry of this stramenopile is given by the presence of mitochondrial-like organelles with a set of pathways: incomplete oxidative phosphorylation chain, partial Krebs cycle, fatty acid metabolism (anabolism and catabolism), amino acid metabolism and protein assembly with iron / sulfur centers. Treatment has traditionally been based on metronidazole and other imidazoles. However, there are a growing number of strains resistant to these drugs. The recent obtaining of the nuclear genome and the biochemical, proteomic, metabolomic and interactomic studies will allow the rational development of new curative drugs. The objective of this review is to describe the metabolism of Blastocystis spp.

Keywords : Blastocystis; metabolism; metronidazole.
