Abstract
Pulmonary lophomoniasis is a rare infection produced by a multiflagellated and anaerobic pyriform or oval protozoan belonging to the family of Lophomonadidae. The study aimed learn the differential diagnosis of lophomoniasis in patients with COVID-19 in northern Mexico. Clinical case of a 37-years-old male patient diagnosed with pneumonia, respiratory syndrome, hemoptysis, and fever, which suggested pulmonary tuberculosis. Bronchial lavage was performed, and laboratory tests were requested, an RT-PCR test to search for SARS-CoV-2, which was positive. The results for TB and KOH for fungi were negative. In addition to the protocol, a fresh examination was performed by placing a drop from the sample on a glass slide and observing it with a 10X objective, then 40X searching for clinically structural elements. As a result, multiflagellated cellular elements in the continuous movement were observed that morphologically correspond to the genus Lophomonas spp concluding the bacteriological protocol of bronchial secretions should consider fresh examination to search for trophozoites of Lophomonas spp. Medical and laboratory personnel are unaware of the protozoa Lophomonas spp, since the fresh examination in the analysis protocol is not considered. This paper reports the first case of Lophomonas infection in a patient caused by chronic lung disease.
