CLINICAL MANIFESTATIONS: Most human infections are asymptomatic.
Acute infection is characterized by rapid onset of nausea, vomiting,
abdominal discomfort or pain, and bloody or watery mucoid diarrhea.
Infected patients can develop chronic intermittent episodes
of diarrhea. Rarely, organisms spread to mesenteric nodes, pleura,
or liver. Inflammation of the gastrointestinal tract and local
lymphatic vessels can result in bowel dilation, ulceration,
and secondary bacterial invasion. Colitis produced by
Balantidium coli often is indistinguishable from that produced by
Entamoeba histolytica. Fulminant disease can occur in malnourished or
otherwise debilitated patients.
