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!
We are pleased to announce that Dr. Charles Calisher has been granted the ‘Cooperstown-esque’ title of Emeritus Professor by CSU. Congratulations Charlie!
Congratulations to Cathy Griffin for her promotion to Accounting Tech IV. Cathy will continue to manage the departmental accounts and perform her current accounting duties, but will now be serving as the Pathology Office Manager.
Be sure to stop by and congratulate Cathy on this well-deserved promotion!
Congratulations to Craig Miller, Anatomic Pathology Resident in the VandeWoude Lab, for receiving a travel fellowship from the Burroughs Welcome Fund to attend the National Veterinary Scholars Symposium in Orlando, Florida in August. The Burroughs Wellcome Fund is an independent private foundation whose mission is to advance the medical sciences by supporting research and other scientific and educational activities.

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

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?

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!
The reception to recognize the residents who have successfully completed their Veterinary Residency Program was held on Monday, June 27 at 3:00pm in the Pathology Glover Gallery.
Faculty, students, and family participated in the event to congratulate Laura, Deanna, Matt, Liz and Brendan on their acheivements. Checkout the Photo Gallery from the event.
Best Wishes Jeanette!
We are sad to report that Jeanette Fritzler's last day with MIP will be Tuesday, July 26. Jeanette has been a valuable MIP employee for the past 6 years; providing the department with excellent service and support. We will miss her smile and great sense of humor, but wish her well in all her future endeavors.
Besides ensuring the students have the supplies they need, the School is Cool Program strives to build self-esteem - an important factor to academic success. Supplies are delivered to Poudre School District school principals or counselors who discreetly distribute the supplies to those students in need.
For just $20, you can help make a local student's educational experience more successful. This amount will sponsor a backpack filled with grade-appropriate school supplies.
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.
MARK YOUR CALENDARS:
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!
CSU Parking Permits are expiring on July 31st!

Congratulations to Jessica Prenni (Proteomics and Metabolomics Facility) on the birth of her bouncing baby girl!
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.
MIP's First Impression of the Telling Lab
Glenn Telling makes an immediate ‘impression’ upon his arrival at MIP (the crane moving equipment to his 3rd floor lab demolished the sidewalk outside the path bldg).
Perhaps this question was:
You no longer need to wonder where all of the packing material from
the new teaching microscopes went…
