Abstract

A 3 years old male dromedarian camel was examined because of anorexia and diarrhea. The affected camel was depressed, tachycardic, eupnic, and had a body temperature of 38.8 °C. Mucous membranes were hyperemic and faeces was soft and mucous coated but of normal colour and odour. Faecal examination revealed a large number of Balantidium coli trophozoites and cysts (15 000/g) and no other parasite could be detected in faecal sample. Seven days after the onset of treatment using intramuscular antibiotic (ampicillin) and anti inflammatory agent (flunixin meglumine), the food consumption, clinical signs and faecal consistency were normal, and faecal examination revealed no parasite. Presence of no other pathogen in faecal samples, and concurrent disappearance of clinical signs and absence of the parasite in the faeces confirmed a diagnosis of balantidiasis. There are only two previous reports about the balantidiasis in camel and the current report is the first report of camel balantidiasis in Iran and supports the proposed role of camels as a reservoir host for Balantidium coli in Iran.
