Professionals from the National Reference Laboratory for Clinical Bacteriology (LRNBC) of the National Institute of Health Laboratories “Dr. Néstor Morales Villazón“ INLASA, Paracoccidioidomycosis (PCM) in a lung biopsy tissue sample.


The Mycology area of ​​the INLASA Bacteriology Laboratory received a lung biopsy sample from a 58-year-old male patient from Palos Blancos, who was treated for pulmonary tuberculosis but who, after receiving 52 doses of anti-tuberculosis drugs, did not show no improvement in his picture. The treating physicians decide to test for PCM.

Through this important finding, it was evidenced that PCM is present in Bolivia and it is possible that, not having been described before, it is not being diagnosed; therefore, it is essential to prepare laboratory methods for their identification.
