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
  • The epidemiology and diagnostics of mycobacterial diseases affecting animals including bovine tuberculosis and Johne’s disease

International Collaborations on Leprosy in the Amazon Rainforest

John Spencer spends nearly six months of every year in the Amazon region of Brazil working to end the stigma associated with leprosy and to help those infected understand, manage, and defeat the disease. As part of the MRL, he has been dedicated for the past 15 years on studying M. leprae, the tiny bacterium that causes leprosy, and his ongoing collaboration with Dr. Claudio Salgado is creating healthier communities in rural Brazil. Watch the videos below to learn more about how the MRL and the One Health Institute at Colorado State University are involved, and read more… 

Knife to Scalpel

A one-of-a-kind instrument built at Colorado State University lets scientists map cellular composition in three dimensions at the nanoscale, allowing researchers to watch how cells respond to new medications at the most minute level ever observed.  Read more…

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

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. To learn more, read the article in the Union E-News.

Diagnostic Breath Test for TB Research

Tuberculosis researchers at Colorado State University have landed a grant from the Bill and Melinda Gates Foundation to develop a diagnostic breath test with potential to revolutionize TB testing and to better control the globally devastating infectious disease.  To learn more, read the article “Gates Foundation funds a new CSU breath test with promise for diagnosing tuberculosis”.

Leprosy Research in Brazil

Leprosy has become prevalent in rural areas of Brazil such as Breves, Brazil.  Watch the videos below to see how Colorado State University and MRL are directly helping Brazil with the combat against leprosy.
