Human blastocysts

Blastocystis hominis: the path to solving the mystery

Blastocystis hominis is a type of microorganism that is often found in the microflora of the human body. This microorganism can live in the human intestine without causing any symptoms of disease or discomfort, but its role in the body remains unclear to this day. In this article, we will look at the details of this mysterious species of bacteria.

Definition and history of the study. Blastocystis was first discovered back in 1995. In 2004, researchers from around the world joined forces and developed a diagnostic system for this type of microorganism. They later discovered that Blastocystis hominis can have many forms, each with different properties. Most Blastocystis species may be beneficial for the development of beneficial microorganisms in the intestine, but their presence in humans may simply be a consequence of the lack of specific selection mechanisms or the reluctance of the immune system to remove these microorganisms.

Description of the species. - The microorganism belongs to dinospores (from the ancient Greek δῑνοφόρος - “related to food”), that is, to fungal unicellular microorganisms. Nevertheless

Blastocystis Hominis (BHS) is a microscopic parasite that infects the body of its host and causes disruption in the functioning of various body systems, deterioration of health and the development of various diseases. The species Blastocystis Hominis belongs to the family Aphelidae and was previously called Trichomonas intestinal amoeba paramecium blastocystis (P. hominis).

Blastocysts are among the simplest microorganisms that can invade intestinal epithelial cells and exhibit their pathogenic properties. The blastocyst is the cyatozoid form of its dysinorhynchus: it is a monotid or dacnotid single parasite of microscopic dimensions: 8-25 µm in length and 6-17 µm in width, and 3-6 µm in thickness, without a characteristic body shape or organ of movement and present in the body humans in a state of intracellular invasion. Parasites emerge from epithelial cells and develop on the intestinal mucosa.

BHS were first discovered in 1920. Now blastocysts are considered one of the most common microorganisms in the world. However, despite their ubiquity in nature, they do not always have an adverse effect on the human body. Research has shown that about 95% of people contain BSH in their gut microbiome, and most remain healthy and intact. However, individuals or populations may be at increased risk of developing diseases associated with BHS and require special attention from gastroenterology clinicians. If necessary, these people can take appropriate measures to eliminate this risk and maintain health.
