Definitions related to blastocystis hominis:
-
A species of parasitic protozoa found in the intestines of humans and other primates. It was classified as a yeast in 1912. Over the years, questions arose about this designation. In 1967, many physiological and morphological B. hominis characteristics were reported that fit a protozoan classification. Since that time, other papers have corroborated this work and the organism is now recognized as a protozoan parasite of humans causing intestinal disease with potentially disabling symptoms.NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021

A species of protozoan parasites in the family Blastocystidae. External transmission of B. hominis is believed to occur by infection with a cyst. The cysts infect epithelial cells of the digestive tract and multiply asexually.NCI ThesaurusU.S. National Cancer Institute, 2021
