Which of the following is a symptom of Entamoeba histolytica infection?

Entamoeba histolytica is a protozoan parasite that causes amoebic dysentery, which is characterized by severe intestinal symptoms. One of the hallmark symptoms of an infection caused by this organism is bloody diarrhea. This occurs as the parasite invades and damages the intestinal lining, leading to ulceration and the presence of blood in the stool.

The presence of blood is not just a sign of gastrointestinal distress but indicates a more serious condition, as it suggests significant mucosal damage brought about by the infection. Recognizing bloody diarrhea as a symptom is critical, especially in clinical settings, as it guides healthcare professionals in diagnosing and managing the infection effectively.

Other symptoms related to Entamoeba histolytica might include cramps or dehydration, but bloody diarrhea stands out as a definitive symptom closely associated with this specific infection.
