A lot of interest has also been generated on the role of probiotics particularly Saccharomyces boularrdii and other natural food compounds on eradication of the parasite.

This can occur when a person doesn’t wash his or her hands thoroughly after using the toilet before preparing food.

Blastocystis hominis

Blastocystis hominis cyst-like forms stained with trichrome. The ameboid form gives origin to a pre-cystwhich develops into thick-walled cyst by schizogony. Certain forms of Blastocystis hominis may be more likely to be linked to an infection with symptoms.

The function of the vacuole is still unclear, however, it has been suggested that, like for many eukaryotic cellsit is for storage purposes. Hence, searching for amoeboid forms may be helpful before antiprotozoal treatment is attempted. Although no one knows for sure how blastocystis gets into the digestive system, experts suspect that blastocystis may get into the intestinal tract through oral-fecal contact.


This article has been cited by other articles in PMC. In vitro susceptibility of Blastocystis hominis isolated from patients with irritable bowel syndrome.

The vacuolar form is otherwise known as central body form because it has a large central vacuole surrounded by a thin band of peripheral cytoplasm which contains other organelles. Food and water safety. The vacuoles stain variably from red to blue in trichrome stain, which is preferred hkminis wet mounts as the organisms can be overlooked as debris. Colony growth on solid medium colonies on solid culture medium using a synthetic medium with added supplements have both been described.

Other functions, such as cell division during reproduction and the deposition of apoptotic bodies, have been proposed, although more tests need to be done to validate these roles.

The appearance of the organism is largely dependent upon environmental conditions as it is extremely sensitive to oxygen. Blastocystis Alexieff Brumpt [1]. Aguilar C, Lucia JF. Zaman V, Zaki M.

Some records show whether the isolates were obtained from symptomatic or asymptomatic carriers. Upcroft P, Upcroft JA.

The prevalence of blastocystis increases in places with inadequate sanitation and poor personal hygiene. Little is known about the organism’s metabolic processes, although one study has identified the role of mitochondrion like organelles in the reduction of ferrodoxins in subtype 7 that plays a role in the conversion of metronidazole into its active state.

Preparing a list of questions can help you make the most of your time with your doctor.
