Thank Ed

After three years in the driver’s seat, Dr. Ed Hoover will officially take his foot off of the MIP accelerator pedal and step down as Dept. Head effective July 31st. Under Ed’s effective leadership, the Dept has made very significant strides the last three years. For example, during Ed’s tenure as DH, MIP has helped christen two new buildings (DMC and RIC), tenured 10 faculty members, published over 360 papers, brought in over $80 million in grant funds, threw its first ‘March Madness’ party and fixed (we hope) the elevator in the Micro Bldg.

We all wish Ed well as he returns to the misfolded nature of full-time prion research – but how can one say thanks to someone who has meant so much for the department? Well for starters, please check out our scan of the largest ‘Thank You’ card in the history of the MIP department!

Detailed Structural and Quantitative Analysis Reveals the Spatial Organization of the Cell Wall of in Vivo Grown M. Leprae and in Vitro Grown M. tuberculosis

Suresh Bhamidi, Mike Sherman, Victoria Jones, Dean Crick, John Belisle, Pat Brennan and Mike McNeil

J. Biol Chem 286: 23168-23177


While sitting in a drinking establishment with colleagues at a scientific meeting one evening last week, the ~25 year old Def Leppard song ‘Pour Some Sugar On Me’ started to reverberate from the jukebox. While I can’t say what thoughts the song induced in the minds of the non-microbiologists in attendance, it made me immediately think of this recent paper by Suresh et al and the idea that the tune should become the theme song of the surface carbohydrate/lipid-centric MRL.

From undergraduate days through medical school, microbiologist wannabes (and those that simply want to pass their micro course and be done with it) memorize the discriminating fact that mycobacteria are acid fast organisms. The reality is that the majority of M. Tb isolated from animal models of infection are not acid fast. This point illustrates the clear need for a deeper understanding of the mycobacterial cell wall and the natural variations in its structure and constituents. That was precisely the goal that this gang of four faculty and their faithful followers set out to accomplish with ninja-like precision.

Crude cell walls were prepared and extracted with chloroform which allowed them to obtain relatively clean preparations of the mAGP portion (mycolates attached to the AG attached to the PG layer) of the cell walls of M. leprae grown in armadillos and M. Tb grown in culture. Using nasty treatments like 2M TFA extraction and 6M HCl hydrolysis, the group was able to determine the relative ratios of mycolic acid, arabinogalactan (AG) and peptidoglycan (PG) in their preparations. They coupled this analysis with mass spectrometry and a few other tricks to provide a comparative biochemical picture of the leprae versus Tb walls. Interestingly, leprae has some variations in the composition of its PG (no N-glycosylated muramic acid and glycine instead of Ala), has shorter galactan units in its AG layer, and almost 3X as much AG per PG in its cell wall. Not content with simply reporting numbers, the group used other available data to prepare models of both cell walls (shown in the picture above).

So why did we choose this work as our coveted MIPublication of the Month® for July? Well my good reader there were three good reasons. First, it represents a fundamental comprehensive analysis of the attached components of the cell wall of the two major mycobacterial pathogens that affect human health. Given the fact that the cell wall is a major anti-mycobacterial drug target as well as an important diagnostic indicator, these data/models may prove pivotal in future analyses. Second, the paper is a terrific example of the synergy that occurs in MIP as 6 faculty members (4 as authors and 2 (John Spencer and Alan Schenkel) in the acknowledgements) and their labs came together to git ‘er done. Finally, the study also strongly implies that M. Tb is a much more sociable organism than M. leprae. Is it just me or do you see the word ‘Hi’ among the mycolic acid that makes up the TB cell wall in the model above?

Thank you

On July 1st, the hard pedaling MIP Office Staff once again successfully completed the annual ‘Tour de Finance’. In Cadel Evans-like fashion, the staff navigated the treacherous mountains of paperwork, sprinted to the fiscal year FY11 finish line and opened up the new accounting records for FY12 – all without the aid of performance-enhancing drugs.

Be sure to take some time out of your busy schedules this week to stop by your facility office and thank some of the hardest working staff in the university. These folks consistently keep the department in tip-top fiscal shape and enable us to provide the very best teaching, service and research at CSU. The MIP staff rocks!

RM ASM Fall Meeting

Mark your calendars

The Fall meeting of the Rocky Mtn Branch of the ASM will take place October 7-8 at Colorado College in Colorado Springs.

Rocky Mountain Virology Annual Meeting

SEPTEMBER 23-25, 2011
Pingree Park Campus

This year's keynote speaker is our incoming Dept Head Dr. Gregg Dean. Gregg will be speaking about his research on lentiviruses (HIV and FIV), innate immunity, and the generation of effective mucosal and systemic immune responses through oral immunization. This will be a wonderful opportunity to meet our new colleague in the relaxed environs of the Pingree campus. This year's meeting also coincides with peak aspen viewing and will feature the Saturday evening barbecue and, of course, a generous contribution from the New Belgium Brewery. So save up your best data and plan on breaking in those new hiking boots this September!

Ines da Silva

Ines Da Silva, a 2008 graduate of our microbiology program and research associate in the AIDL, passed away on June 24th in a motor vehicle accident in Nebraska. Born in Portugal and a Ft. Collins resident since 2001, Ines left a strong positive impression on everyone who knew her. Touring the bike trails and white water rafting trips just won’t be quite the same without her. A celebration of her life was held on July 1st in Spring Canyon Park. The united MIP community offers its sincere condolences to the da Silva family and will strive to continue the research Ines performed to ensure her professional legacy.

Andrea Guillory can get some pretty bizarre questions over the phone.

Perhaps this question was:

  1. "Would it be possible to get the entire department together this afternoon for a short presentation on green initiatives"?
  2. "Hi – would you mind telling Dr. Akkina that his dry cleaning is ready to be picked up?"
  3. "Good morning – this is K99 and you’re live on the radio!"

NIH Happenings
  • Attention Students/Postdocs/Residents: Need help paying your student loans? NIH might be able to help

    Check out the NIH’s Loan Repayment Program (LRP).  NIH's LRP could repay up to $35,000 of your educational debt each year.  While NIAID only supports a Clinical Research LRP and a Pediatric Research LRP, other institutes might have programs that fit your particular situation.

  • Do you need prior approval before you make that change to your NIH-funded project?

    To answer this important question, you want to carefully check out the NIAID Funding Webpage (or potentially risk losing your funding).
