Abstract
Balantidium coli is a ciliated protozoa which can infect humans. Although the infection is uncommon, it tends to be more frequent in the tropics and subtropical regions. It is often asymptomatic but may present with gastrointestinal symptoms. Few cases of urinary balantidiasis have been reported but faecal contamination could cause diagnostic dilemma.
