Blastocystis Hominis Disease Disease

BLASTOCYSTIS HOMINIS DISEASE DISEASE
Blastocystis hominis is a common microflora found in the human intestine. Today taxonomy clearly identifies Blastocystis hominis as a single-cell type. Analysis of the field of genes, similar to Entamoeba histolytica amoeba.
1. BLASTOCYSTIS HOMINIS DISEASE DISEASE FORM
The size varies, the vacuoles in the fresh faeces range from 3 - 63 ,m, on average 10 -12 µm, may encounter smaller forms, the more abundant forms do not have a size of 3-10 µm, very refractive

. , there is a vacuole in the middle, a thick shell has two layers with many small nuclei and a capsule containing mucus on the periphery, these particles are ejected into small particles when making the template.
Blastocystis hominis easily decomposed by tap water, it should be distinguished to not confuse with amoeba cysts. In culture media, Blastocystis hominis exists in 3 different forms: vacuoles, schizophrenia with many identical pieces and amoeba
2 BLASTOCYSTIS HOMINIS DISEASE DEVELOPMENT PROCESS
The developmental cycle in humans is not known, thick cysts are excreted in the feces, and this is the form of infection, mainly through fecal - oral route. In the human intestine, the vacuole form divides according to the cell division into the precursor form, then the thin-walled capsule, in which there are many vacuoles broken.



. Some turn into amoeba, then into cystic prognosis, thickened cysts and excreted in feces and infectious.
3. EPIDEMIOLOGICAL CHARACTERISTICS OF BLASTOCYSTIS HOMINIS
The owner of this parasite is limited to humans, monkeys, and cobaye. 10% - 20% of the world's population, usually in developing countries (30% - 50%), higher than in developed countries (1.5% - 10%) in the presence of parasites In feces, the stool is more common in people with digestive disorders than those without symptoms of digestive disorders, homosexuals are those who carry this parasite in the stool more often
4 Clinical pathology and clinical manifestations
The pathogenic role of Blastocystis hominis in normal individuals is controversial, but in immunocompromised individuals the pathogenic role of Blastocystis hominis has been demonstrated.
No Blastocystis hominis was found invading the intestinal mucosa.
Symptoms are common in patients infected with Blastocystis hominis, acute or chronic diarrhea, abdominal pain, flatulence, fatigue ..



.. Stools without moldy stool, sometimes viscous mucus like dysentery. No association was found between the number of Blastocystis hominis found in feces and clinical symptoms.
5 DIAGNOSTIC DISEASES BLASTOCYSTIS HOMINIS
Observing fresh or fixed faeces in MIF or F2AM solution, usually see the small, peripheral vacuoles with small particles.
6. TREATMENT OF BLASTOCYSTIS HOMINIS
There is no need to treat asymptomatic cases. People with symptoms should eliminate all other intestinal pathogens. Metronidazole. Some use trimethorim-sulfamethoxazole and nitazonamide.

7. PREVENTION OF BLASTOCYSTIS HOMINIS
Eat cooked, drink boiled, do not eat at risk of infection
Mainly based on faecal hygiene, wash hands thoroughly before eating and after going to the toilet
