Hint: Entamoeba histolytica is a parasitic organism that can cause amoebiasis in humans and other animals. Since it is anaerobic, it is predominantly found in those parts of the body that do not contain oxygen. The infection can be determined through a stool test and if not treated, it can be fatal.
Complete answer:
Entamoeba histolytica is found in the intestines of human beings.
This organism can cause the disease amoebiasis, which is spread through contaminated food and water. This disease occurs predominantly in tropical countries with unsanitary conditions.
The active stage of this parasite is called trophozoites. Trophozoites exist only in the intestines and the faecal matter of the infected person. Once outside, the organism survives in the form of cysts in soil, water, food, etc. The infection occurs when an individual consumes something that has either been in contact with the faecal matter of an infected person or contains the cysts of the parasite.
Inside the body, the cysts release the trophozoites in the small intestine. These trophozoites then enter the large intestine and invade the cells.
Symptoms of amoebiasis are:
• Diarrhoea (may contain blood at times)
• Abdominal cramps
• Loss of appetite
• Flatulence
• Fatigue and weakness.
Hence, the correct answer is option (D).
Note: Entamoeba histolytica invades the epithelial cells of the large intestine. Without any intervention, the parasite can bore through the layers and cause ulcers and abscesses in the intestine. If the organism enters the bloodstream, it can spread to other organs such as the liver, spleen, lungs, and even the brain. That is why if left untreated, it can be fatal.
