Concurrent Infection of the Urinary Tract with Encephalitozoon cuniculi and Enterocytozoon bieneusi in a Renal Transplant Recipient

A urinary tract coinfection, caused by Encephalitozoon cuniculi genotype II and Enterocytozoon bieneusi genotype D, was identified in an HIV-seronegative renal transplant recipient kept under lifelong immunosuppression. To our knowledge, this is the first report describing concurrent infection with these two microsporidia species in organ transplant recipients.
