Abstract

Here, we describe two cases of Lophomonas blattarum bronchopulmonary infection. The first patient was diagnosed for long years with chronic lymphocytic leukemia and was stable all through his course. The second patient was an immunocompetent patient. Both patients presented within a month for admission with a non-resolving lower respiratory tract infection, they received several antimicrobials as an outpatient and initially as inpatients without benefit. Broncho-Alveolar Lavage (BAL) revealed the causative parasite on the fluids wet mount examination. Both improve remarkably on metronidazole treatment and were discharged home. Around two weeks after discharge from the hospital, both patients were in good health with no fever and respiratory symptoms of bronchopneumonia.
