Entamoeba histolytica causes
Entamoeba histolytica is an anaerobic parasitic amoebozoan, predominantly infecting humans and other primates causing amoebiasis or dysentery. Symptoms can include fulminating dysentery, bloody diarrhoea, weight loss, fatigue, abdominal pain. Dysentery is an intestinal inflammation, primarily of the colon. It can lead to mild or severe stomach cramps and severe diarrhoea with mucus or blood in the faeces. So, the correct answer is 'Dysentery'.
