[A case of coinfection by Balantidium coli and HIV in French Guiana].

A case of balantidial dysentery is reported in a patient infected with the HIV in French Guiana. This case is the first described in medical literature. The patient presented also a disseminated histoplasmosis. Immunosuppression probably favoured the evolution of asymptomatic carriage to clinical dysentery. This clinical case did not present any complications. Treatment with doxycycline had to be carried out for 20 days in order to obtain a clinical and parasitological cure.
