RESUMEN
Blastocystis es un stramenopile o cromista, pleomórfico no móvil. Se han identificado diecinue-ve subtipos de este organismo (ST1-ST19). Tiene una presencia a nivel mundial. Este microor-ganismo tiene un metabolismo intermediario anaeróbico. Un aspecto interesante de la bioquími-ca de este stramenopile está dado por la presencia de organelas similares a mitocondrias con un conjunto de rutas cadena de fosforilación oxidativa incompleta, ciclo de Krebs parcial, metabo-lismo de ácidos grasos (anabolismo y catabolismo), metabolismo de aminoácidos y ensamblaje de proteínas con centros hierro/azufre. El tratamiento se ha basado tradicionalmente en metroni-dazol y otros imidazoles. Sin embargo, hay un número creciente de cepas resistentes a esos medicamentos. La reciente obtención del genoma nuclear y los estudios bioquímicos, proteómi-cos, metabolómicos, interactómicos permitirán el desarrollo racional de nuevos fármacos curati-vos. El objetivo de esta revisión es describir el metabolismo de Blastocystis spp
ABSTRACT
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 phos-phorylation 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.
