Blastocystis hominis, previously known as a yeast, is being considered a

to cause gastrointestinal disorders in patients with immunodeficiency
diseases . We present here the results of a coproparasitological study
carried out in Cuban AIDS patients in whom the prevalence of B. hominis
infection had never been studied.
