Entamoeba Histolytica Amoeba And Harm Caused To Humans

Entamoeba Histolytica amoeba is a protozoan parasite that causes disease in humans.
Shape: the body consists of a cell, prosthetic motor formed from extracellular material, nucleus with central chromosomes. Entamoeba histolytica has 3 different shapes:
Active form of erythrocyte (magna form): is the amoeba causing disease, size 20-40mc, in the intracellular matrix with red blood cells and they move quickly by releasing prostheses from the exogenous layer. This form occurs when acute amoeba in the intestine or liver abscess, lungs, brain, .

.
Small active form, not erythrocyte (minuta form): does not cause dysentery, size 10-12μc, in intracellular material without red blood cells, they also move on the artificial leg.
Cystic form (coccyst = cyst): is able to protect and spread of amoeba. The capsule is spherical, immobile, has a very thick shell and is refractive under a microscope Elderly cells have 4 new nucleus as the source of infection Cysts that exist in the outside and in healthy people carrying cysts are called germ storage.
Development cycle
The process of invading Entamoeba histolytica amoeba causes human disease
Entamoeba histolytica amoeba infections are mainly caused by ingestion of amoeba cysts from food.



. Amoeba in the human intestine may include saprophytic and pathogenic cycles.
Saprophytic cycle: When entering the human intestine through eating, amoeba cysts drain and divide themselves with the protoplasm and form 8 small amoeba (minuta form). This type of amoeba infected but not cause disease. These forms can be transformed into cysts and excreted in the faeces into the environment.
Pathogenesis cycle: in the intestine, amoeba can transform from the minuta form into the active form of erythropoiesis (magna form) and cause disease The erythematous erythematosus is capable of causing necrosis, creating abscesses of abscesses (buttons of nail) in the colon wall Here amoeba grow very strong and they can turn into minuta form to excrete in the feces. The abscesses are superinfected and cause lesions that cause increased mucus secretion, increased contractility, corrosion of blood vessels and stimulation of nerve plexus. The result is dysentery syndrome with nasal mucus and bowel pain. After treatment, the small pressure will become scarred deforming the colon, which is images of colonic spasm.



. In addition to the erythrocyte amoeba, which is excreted in the feces, some of these forms enter the bloodstream and travel to the liver causing amoeba liver abscess, sometimes to the lung causing lung abscess, more rarely with amoeba to the brain causing abscess. amoeba brain.
Harm of amoeba
Amoeba intestinal pathology causes bleeding and bacterial superinfection, patients with anorexia, insomnia, leading to rapid decline in fitness.
Amoeba causes intestinal or semi-intestinal syndrome caused by scarring of ligaments that constrict the colon
Amoeba serious disease due to deep penetration into the intestinal wall, can cause perforation.
Amoeba causes amoeba hepatitis and amoeba liver is very dangerous.
Amoeba sometimes affects the lungs, brain, muscles, and bones, causing serious harm.
Pathological manifestations
Acute amoeba in the gut or dysentery amoeba
Having bloody bowel movements many times a day (5-20 times) will usually have no stool.
Ore abdominal pain. Triangent dysentery: abdominal cramps, grit and nose mucus.



.
Weakening condition worsened without treatment.
Palpation of the intestines, rectal and colonoscopy show ulcers covered with mucus, wounded buttons (press nail)
Radiographs of colic constricted colitis.
Progression of the disease becomes chronic if not actively treated, with cases of perforation, intussusception, intestinal granuloma.
Intestinal amoeba
Liver abscess due to amoeba: pain in the liver, hepatomegaly, high fever 38 -39ᵒC, ultrasound with abscess, poking with chocolate color.
Amoeba abscess: secondary to hepatic amoeba abscess and therefore also at the base of right lung, sometimes abscess self-discharge pus by coughing out chocolate pus.
Abscess due to amoeba in other places such as spleen, brain, bone, anal ulcer.
Diagnose
clinical
Abdominal pain, ore pain, straining, bloody stools
Lower right flank pain, hepatomegaly, high fever 38 -39ᵒC
Subclinical
Direct stool examination for an active or cystic form is the definitive diagnostic criteria.
Fecal examination by Ether - formalin detected cysts used in community investigation.
An ultrasound of the liver or puncture of the amoeba.




Good immune diagnosis with organized amoeba.
Preventing amoeba
Good manure management and handling
Protect clean water from pollution.
Against insects carrying germs.
Detect and treat cases, especially healthy people carrying amoeba cysts.
Propagate, educate about clean personal hygiene, perform boiling eating and drinking, wash hands before eating and after going out. No indiscriminate discharge.
