Introduction. Lophomonas blattarum is a rare cause of bronchopulmonary and sinus infection. This paper presents a rare case of Lophomonas sinusitis. Case Presentation. The patient was a 31-year-old woman who was admitted because of a history of upper respiratory infection and sinusitis. Direct microscopic examination of the sputum and nasal discharge showed large numbers of living Lophomonas bl...

The natural habitat of the multiflagellate protozoon Lophomonas blattarum is as an endocommensal in the hindgut of insects such as cockroaches. However, it also causes bronchopulmonary disease in humans. The aim of this paper was to review the literature on this organism in the context of respiratory disease. The biology epidemiology, route of transmission, pathogenic mechanisms and diagnosis m...

Human infections with Lophomonas blattarum are rare. However, the majority of the infections occurred in China, 94.4% (136 cases) of all cases in the world. This infection is difficult to differentiate from other pulmonary infections with similar symptoms. Here we reported a case of L. blattarum infection confirmed by bronchoalveolar lavage fluid smear on the microscopic observations. The patie...

Background: Lophomonas blattarum is protozoan generally parasitizes in the intestinal tracts of some arthropods. It can infect adults and children with unspecific respiratory symptoms. We aimed to investigate the frequency of Lophomonas blattarum in children with respiratory symptoms in North East of Iran. Materials and Methods: One hundred fifty-six children with respiratory symptoms were inv...

We thank Dr. Martínez‐Girón for the interest in our article about bronchopulmonary Lophomonas blattarum infection.[1] However, all the reported cases of bronchopulmonary L. blattarum infection are just relied on light microscopic findings. None of the evidences in literatures can be further confirmed by culture, animal models, or multiple molecular procedures. In addition, there is no evidence ...
