Question

Small white stone-like Charcot-Leydon crystals are found in the feces of a person suffering from
(a) Amoebiasis
(b) Malaria
(c) Giardiasis
(d) Chagas’ fever

Answer 1

A person suffering from this disease may have no, mild, or severe symptoms. Cysts of this organism can survive in the soil for up to a month and under fingernails up to 45 minutes. It mainly ends up in the liver of the person causing something known as the liver abscesses.

Complete answer:
In the feces of a person suffering from amoebiasis small white crystals of Charcot-Leydon can be seen. It is also known as amoebic dysentery and is caused by any one of the amoebae of the Entamoeba group especially by the Entamoeba histolytica. The cell nucleus of this genus contains an endosome, a central body, and a ring of finely sized granules that are attached to the nuclear membrane of the cell. The primary infection is often asymptomatic and is infected in the large intestine. From the invasion and ulceration of intestinal walls, the person may suffer from abdominal pain, diarrhea, and fever. The secondary infection occurs in the liver, brain, spleen, and lungs. The symptoms of this disease may include cramping, pain, diarrhea, or bloody diarrhea. It is most common in tropical areas and untreated water areas. E. histolytica is spread through drinking or eating uncooked food like fruits which may have been in contaminated local water.
So, the correct answer is 'Amoebiasis'.

Note: Amoebic dysentery responds well to treatment and can be cleared up in about 2 weeks. But if it is a more serious case with the parasite appearing in the internal tissues or organs antibiotics can be taken. The nitroimidazole drugs (like metronidazole and tinidazole ) are taken for treating gastrointestinal amebiasis, they kill amoebas in the blood, wall of the intestine, and in the liver.
