MIP's very own Dr. Anne Lenaerts is currently featured on the Stop TB Partnership website as part of the Global Plan to Stop TB. Anne is highlighted as one of the top woman innovators in the tuberculosis research field in an effort by this year's campaign to focus on individuals around the world who have found new ways to stop TB and can serve as an inspiration to others. The feature describes Dr. Lenaerts' tuberculosis research, her role in MIP's Mycobacteria Research Laboratory and recent progress with finding new drugs to treat TB. This is definitely an article you want to check out!
Laurel Hascall-Dove was recognized as the Outstanding Graduating Senior at the December 2009 undergraduate commencement ceremony. This award is given to students who have a record of academic excellence and/or service to the department or the community. Laurel has certainly been a very good student. She graduated with a cumulative GPA of 3.64, which she earned completing the rigorous requirements for a B.S. degree in microbiology with a minor in Biomedical Sciences. Laurel’s academic performance is all the more impressive given that in addition to carrying a full course load each semester, she was also worked part-time to help pay for her education. For the last year, Laurel has been a research assistant in the laboratory of Dr. Randy Basaraba.
Despite her busy class and work schedules, Laurel somehow also found the energy to devote her time and talents as a volunteer at Poudre Valley Hospital in a variety of positions, including running the flower desk, serving as a member of a play therapy study with autistic children and, most recently, working in the emergency room
Laurel aspires to become a physician, and based on her scholastic achievements, research and volunteer experience, and commitment to community service she will very likely achieve her goal.
Congratulations Laurel and good luck in your future endeavors!
Gopi Palanisamy presented his final seminar entitled, "Role of oxidative stress in the pathogenesis of experimental tuberculosis in guinea pigs " on Tuesday, January 19, and defended his PhD dissertation immediately following the seminar. His advisors are Dr. Randy Basaraba and Dr. Ian Orme.

The World Health Organization has set a goal of eliminating tuberculosis by 2050. Unfortunately however, all current predictions indicate that we are not going to meet this goal. So do you think that TB researchers like Karen Dobos, John Belisle or Pat Brennan are just going to sit by idly and accept defeat? Heck no! Our Three Amigos© are working with a team from Columbia to develop new tools to prevent TB infections from spreading. This month's MIPublication of the Month® is a great example of some of their recent work to estimate the value of using interferon gamma responses in patients as a prognostic marker for developing TB.
While the Denver Broncos may have played the second half of the season this year liked they had TB, household contacts of TB patients are a much better cohort to focus on for studying disease outcome following exposure. The textbooks claim that 10-20% of folks who are exposed to Mycobacterium tuberculosis (M.tb) will develop disease sometime in their lives. The problem with this claim, however, is that it's derived from data that are based on the tuberculin test - an assay that basically detects exposure to all mycobacterial species, not just those that cause TB. (In case your wondering, we are all surrounded by a ton of environmental mycobacteria - just for fun one day take a sample of what's growing on the inside of your showerhead and let the MRL analyze it for you...). Therefore in their study, Our Three Amigos© and their Colombian colleagues focused on a better antigen test - the use of a highly M. tb-selective CFP-10 antigen and its ability to induce IFNγ from blood cultures using a very sensitive 7 day assay. Over 2,000 household TB contacts from the Medellin, Columbia metro area (an area with a intermediate incidence of TB [27.7 cases per 100,000 people]) were enrolled in the study and assayed for TB exposure using classic tuberculin testing along with a set of new fangled IFNγ-inducing M.tb antigens, including CFP-10. Their results largely supported both the use of CFP-10 reaction as a biomarker for M. tb exposure as well as a hypothesis put forth by Andersen and colleagues in 2007 that infected individuals that produce a high level of IFNγ in response to M.tb are at a much greater risk of developing overt disease.
So why did we select this paper as the first coveted MIPublication of the Month® for the new decade? There were two main reasons. First, the study represents basically the first powerful, population-based tuberculosis analysis using the new IFNγ-based M. tb exposure assays and thus gives confidence for their use as a tool for the diagnosis and prognosis of the disease. Second and most importantly, prior to this study, the policy of the Colombian National Tuberculosis Control Program was to only provide isoniazid therapy to prevent the development of tuberculosis to kids <5yrs old if they had a tuberculin test >10mm and no BCG vaccine. This paper clearly showed that in their cohort of household contacts, 22% of the tuberculosis cases were in kids 4 yrs old or less - an astounding incidence ratio when one considers that the TB rate in the general Medellin child population is ~3%. The group brought this information to the Public Health Director of the Columbian Ministry of Social Protection and got their message heard loud and clear. Columbian health officials have now changed their official policy and will offer isoniazid preventive therapy to all child household contacts regardless of age and vaccine status. The bottom line: THIS STUDY HAS ALREADY DIRECTLY CONTRIBUTED TO SAVING LIVES FROM TUBERCULOSIS. If that doesn't qualify a paper as worthy of MIPublication of the month, well by golly nothing does.

Originally due back in operation on January 6th, the elevator in the Micro Bldg has now officially taken an extended Sabbatical and is due to be back in service on January 27th (that’s 2010, we think...). Pictured above are four Micro inhabitants who are very glad they didn’t need to invest big bucks in a Stairmaster to keep their New Year’s resolutions.
MIP is sad to announce that Dr. Debra Kamstock will be leaving the department. The good news is that she will still be at CSU as she has accepted a position within the Animal Cancer Center where she can pursue her interests in cancer research.
We wish her all the best in her research, and look forward to continued opportunites to work with her
