The Laboratory of Applied Research in Mycobacteria (LaPAM) combines bioinformatics and wet lab experiments to understand and better control tuberculosis (TB) in humans and animals. We believe that, in order to achieve the UN sustainable development goal of eradicating TB, we need to create strategies to fight all pathogens causing the disease in humans, including the ones responsible for zoonotic TB and those restricted to certain regions of the globe. We are advocates of the One Health concept to improve global health. Our research is mainly focused on bacterial genomics and the effect of genetic variations on bacterial phenotype, with an emphasis on the differences among species and lineages of the M. tuberculosis complex.

The LaPAM was founded in 2016 by Professor Ana Marcia de Sá Guimarães from the Department of Microbiology of the Institute of Biomedical Sciences, University of São Paulo, Brazil. It is located at 1374 Professor Lineu Prestes Avenue, Cidade Universitária Campus, São Paulo, Brazil. Procedures involving live tuberculous mycobacteria are performed at the Biosafety Level 3+ Laboratory “Prof. Klaus Eberhard Stewien” located across the hallway from LaPAM. 

Our mission

To produce science applied to the study of tuberculous mycobacteria and educate researchers to act on the various microbiology research fields.

Our philosophy

The LaPAM welcomes students, researchers, staff and collaborators of all backgrounds.  In our laboratory, every individual, regardless of gender, gender identity, sexual orientation, race, ethnicity, socio-economic status, disability, nationality, political or religious views, or position within the institution, is valued. We also encourage an environment of collaboration, open communication, and trust, which welcomes diversity and respects differences of opinions.
