Amebiaz, As well as giardiasis, refers to invasive intestinal infections.
It is called by the simplest microorganisms of Entamoeba histolytica. Dysentery amoeba. The disease often has a protracted and chronic course, entails ulcerative lesions of the colon and the formation of centers of abscess in other organs.
Amoeba in the intestine
This parasite has 2 life cycles - vegetative (active) and cystic (in a state of rest).
Representatives of the autonomic form are actively introduced into the wall of the colon and in the case of acute amebiasis, they appear in faeces. But cysts, that is, inactive forms of amoebae appear in feces, which recover from acute amebiasis or suffer from chronic human course, and also people have carriers of amoebae.
Infection occurs as always in the case of such fecal-oral infections, through unwashen hands, contaminated food and water. Especially often-in the summer.
In the human digestive tract, cysts enter, in the large intestine they "come back to life", penetrate the gut mucosa, multiply there, causing multiple abscesses of the intestinal tissue. In the most serious cases, even perforation of the intestinal wall and peritonitis may occur. Harvesting of ulcers occurs with the formation of scars and narrowing of the lumen of the gut up to obstruction.
Through the blood vessels of the submucous layer of gut, amoeba can enter other organs and then develops:
- Liver amebiasis.
- Ambiasis of the lungs.
- Ambiase skin.
All these types of amebiasis are manifested by local abscesses.
Symptoms of amebiasis
- Weakness and low-grade temperature.
- Rare smelly mucous membrane (in the early days up to 5 times a day, then - up to 15-20 times).
- Pneumorrheal pains in the right anus and in the lower abdomen.
Diagnosis and treatment of amebiasis
Laboratory tests of feces immediately after defecation show the presence of vegetative (in the case of acute flow) or cyst (in the case of chronic course) forms of ameb, and rectal studies of the intestine - ulcers on the walls of the large intestine. It is important to distinguish amebiasis from other intestinal infections with similar symptoms caused by other microorganisms.
For treatment, strong drugs are used - amoebociids, which can directly affect all life forms of this parasite, as well as antibacterial drugs that affect the amoeba indirectly. The prognosis of treatment of amebia is favorable in the event that the process has long gone into multiple abscesses, and they have not been diagnosed in time, the patient may even be at risk of death.
