Endosymbiosis in Blastocystis hominis
Experimental Parasitology, 1976Abstract Examination of eight strains of axenically grown Blastocystis hominis by Nomarski interference optics revealed the presence in all strains of intracellular bacterialike spheres and rods, which were named alpha. These structures were confirmed by transmission (TEM) and freeze fracture (FEM) electron microscopy.

Ultrastructure of blastocystis hominis
Zeitschrift f�r Parasitenkunde, 1973Ultrastructural studies of modified Boeck-Drbohlav egg slant cultured Blastocystis hominis reveal ameba, granular, and vacuolated forms of this organism. The ameba form shows a thick filamentous surface layer, a less conspicuous solid central body than the granular and vacuolated forms and very large mitochondria.

Blastocystis hominis and travelers
Travel Medicine and Infectious Disease, 2005B. hominis is a unicellular protozoan commonly identified in stool specimens of travelers who have returned from tropical countries. It has a world-wide distribution, and infection is more common in developing countries compared to industrialized nations.

Epidemiology and pathogenicity of Blastocystis hominis
Journal of Clinical Microbiology, 1990A prospective study was performed on a large outpatient population to evaluate the epidemiology and pathogenicity of Blastocystis hominis. Patients with stool specimens positive for B. hominis and negative for other bacterial and parasitic pathogens were sent a questionnaire and were requested to submit a follow-up specimen for ova-and-parasite ...

In vivo encystation of Blastocystis hominis
Parasitology Research, 2009Blastocystis from infected stools of a person who showed chronic symptoms of abdominal discomfort and diarrhea were examined over a 6-month period, using transmission electron microscopy, for the ultrastructural changes from vacuolar to cystic stage. The study confirms the irregular shedding phenomenon of the organism previously reported, and for the ...

Clinical significance of Blastocystis hominis
Journal of Clinical Microbiology, 1989A total of 19,252 stool specimens from 12,136 patients were examined by direct microscopy and the ethyl acetate-Formalin concentration method during the last 2 years. All liquid specimens and those in which parasite identification was difficult or equivocal were also examined in trichrome-stained preparations. A total of 3,070 intestinal parasites were

Endocytosis in cultures of Blastocystis hominis
International Journal for Parasitology, 1989A study of the function of the electron-dense pits in the vacuolar and granular forms of Blastocystis hominis was undertaken. Immuno-electron microscopy using anti-clathrin antibody and colloidal gold demonstrated clathrin to be associated with all forms of the pits and some cytoplasmic vesicles.

Protease activity of Blastocystis hominis
Parasitology Research, 2006Parasite-derived proteases are important for the parasite life cycle and the pathogenesis of the disease they produce. Proteases of intestinal protozoan parasite Blastocystis hominis were studied for the first time with azocasein assays and gelatin SDS-PAGE analysis. Parasitic lysates were found to have high protease activity and nine protease bands of
