About the MRL

The Mycobacteria Research Laboratories was founded some 25 years ago by Dr. Patrick J. Brennan and colleagues with the intent of generating an internationally recognized center of excellence for the study of mycobacterial diseases and pathogens. Since then, the MRL has been at the forefront of mycobacterial fundamental and translational research. Research programs in the MRL utilize state-of-the-art techniques and facilities to address

  • tuberculosis vaccine and drug development,
  • leprosy and tuberculosis diagnostics,
  • the study of nontuberculous mycobacterial diseases and Buruli ulcer,
  • and the epidemiology and diagnostics of mycobacterial diseases affecting animals including bovine tuberculosis and Johne’s disease.

Team lands NIH funds to examine tuberculosis and metabolism


The MRL team from Colorado State University will play a crucial role in a new project funded by the National Institutes of Health to examine factors that make people susceptible to the bacterium that causes tuberculosis and to discover new treatment strategies. Read more.




MRL Researchers – Discovery


MRL researchers have discovered that the pathogen, Mycobacterium leprae, can live for months inside protective host amoebae that are common in water, soil and plants – then can be easily transferred to trigger infection. Read more.





Outstanding Work


Crystal Shanley, a Research Associate in Dr. Ian Orme’s lab, has been recognized for her outstanding achievement in the care of research and teaching animals. Crystal was awarded the Technician of the Year for 2014. Crystal was instrumental in training an international Gates Foundation TB staff team in Witbank on the needed techniques for guinea pig vaccinations. Her stress-free procedure has been adopted by other laboratories in the TB field.




Zoonotic TB Research

Colorado State University

Dr. Francisco Olea-Popelka, aveterinary epidemiologist with the MRL, is the chairman of The Union’s Zoonotic TB Sub-Section. The sub-section monitors the transmission of tuberculosis between animals and people, especially in underserved communities in developing countries.
