Which of the following is not a symptom of a disease caused by E. histolytica?

Nasal discharge

 Entamoeba histolytica is a protozoan parasite that primarily resides in the large intestine of humans and is responsible for causing amoebiasis, also known as amoebic dysentery. Amoebiasis is characterized by various symptoms, including constipation, abdominal pain, and cramps. Additionally, infected individuals may pass stools that contain excess mucus and blood clots.

The transmission of E. histolytica occurs through the contamination of food and water sources with fecal matter containing the parasite. One of the ways this contamination can occur is through houseflies, which act as mechanical carriers of the parasite. Houseflies can come into contact with infected feces and then transfer the parasite to food and food products, thereby contaminating them. When individuals consume contaminated food or water, they can become infected with E. histolytica.

Drinking water and food contaminated with fecal matter are considered the primary sources of E. histolytica infection. This highlights the importance of maintaining proper hygiene and sanitation practices, such as ensuring the proper disposal of feces and practicing good personal hygiene, to prevent the transmission of the parasite. By maintaining clean water sources and safe food handling practices, the risk of infection can be significantly reduced.

 However, nasal discharge is not typically associated with the disease caused by E. histolytica. Nasal discharge is more commonly associated with respiratory infections or allergies rather than amoebiasis. Therefore, option (d) "Nasal discharge" is the correct answer as it is not a symptom of the disease caused by E. histolytica
