Dysentery Caused by Balantidium coli in China

ABSTRACT

Balantidium coli human infection predominantly occurs in tropical and subtropical regions in the world. Human case is extremely rare in China. This report details a case of B. coli infection in a 68-year-old man in China, who presented with history of abdominal pain, tenesmus, diarrhea with blood and was diagnosed as B. coli-caused dysentery. Our case indicates possible occurrence of Balantidium coli-related disease in cooler climates. This case is presented not only because of its rarity but also for future references.
