A 24 year old man with AIDS diagnosed in 1989 and a history of several episodes of pulmonary pneumocystosis developed chronic diarrhea and severe epigastric pain. Endoscopy revealed a granular intestinal mucosa. There was atrophy of villi and Giemsa, Ziehl-Nielsen and Gram staining identified 1.5 to 2 u spores in the cytoplasm of intestinal cells. Transmission electron microscopy of the spores revealed a thick wall, a sporoplasm with a nucleus, ribosomes, a posterior vacuole and a polar filament with multiple coils; no mitochondria were seen. Thus, the patient had intestinal microsporidiosis caused by Enterocytozoon bieneusi. This is a rare pathogen recently identified in man.

UI MeSH Term Description Entries
D007421 Intestine, Small The portion of the GASTROINTESTINAL TRACT between the PYLORUS of the STOMACH and the ILEOCECAL VALVE of the LARGE INTESTINE. It is divisible into three portions: the DUODENUM, the JEJUNUM, and the ILEUM. Small Intestine,Intestines, Small,Small Intestines
D008297 Male Males
D008854 Microscopy, Electron Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen. Electron Microscopy
D003967 Diarrhea An increased liquidity or decreased consistency of FECES, such as running stool. Fecal consistency is related to the ratio of water-holding capacity of insoluble solids to total water, rather than the amount of water present. Diarrhea is not hyperdefecation or increased fecal weight. Diarrheas

D000328 Adult A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available. Adults
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

The most common include PNEUMOCYSTIS PNEUMONIA, Kaposi's sarcoma, cryptosporidiosis, herpes simplex, toxoplasmosis, cryptococcosis, and infections with Mycobacterium avium complex, Microsporidium, and Cytomegalovirus.
