Mycobacterium leprae on Palatine Tonsils and Adenoids of Asymptomatic Patients, Brazil

We investigated palatine tonsil and adenoid specimens excised from otorhinolaryngological patients in a leprosy-endemic region of Brazil. Fite-Faraco staining identified Mycobacterium spp. in 9 of 397 specimen blocks. Immunohistochemistry and molecular analysis confirmed the presence of Mycobacteriu...

Immunohistochemistry and molecular analysis confirmed the presence of Mycobacterium leprae, indicating that these organs can house M. leprae in persons inhabiting a leprosy-endemic region.
