Congratulations to Dr. Patricia Cole for receiving the 2013 CVMA Outstanding Faculty Award for her selfless contributions and support for her students. She is known as a gifted instructor among students and colleagues, carrying the title of veterinarian with pride and encouraging her students to do the same. Please note that MIPnews respectfully requests that even though she's on top of the veterinary world right now and clearly 'unforgettable', please refrain from referring to her as 'Pat 'King' Cole'.....
The Annual American College of Veterinary Pathologist (ACVP) Board Exam was held September 17-19. Great job to all! Passing any or all is an accomplishment and we're proud of your efforts and success!

Correlates of Immune Protection Following Cutaneous Immunization with an Attenuated Burkholderia pseudomallei Vaccine
Ediane Silva, Andrew Goodyear, Marjorie Sutherland, Nicole Podnecky, Mercedes Gonzalez-Juarrero, Herbert Schweizer and Steve Dow
Infection and Immunity, published online October 7, 2013
Want to know what’s worse than the smell of roofing tar on a warm autumn afternoon compounded by the incessant hammering of a wrecking crew dismantling a fifty year old freezer/coldroom down the hallway? Melioidosis caused by Burkholderia pseudomallei. Breathe in this little gram negative bacterial rod (instead of those wonderful sulfer compounds in roofing tar) and you may very well be in for a bout of pain, pneumonia and widespread abscesses that is oftentimes fatal without treatment (and if it doesn’t get you the first time around, the bacteria can cause chronic infections that crop up again down the road). To make matters worse, efflux pumps in the bug make it inherently resistant to many antibiotics and there is no vaccine. Given the prevalence of this pest in Southeast Asia, Northern Australia and parts of South and Central America – not to mention the fact that sensitive methods are detecting it in novel places around the globe – we could really use a vaccine against this germ.
Ediane et al analyzed whether or not an attenuated ΔpurM derivative of the Bp82 strain of B. pseudomallei might be a good candidate for a vaccine when delivered by the sub-cutaneous route. This Bp82 strain is so weakened that it has never been observed to revert to virulence and its actually been approved for experiments at the BSL2 level in standard labs (rather than restricted to study behind the BSL3 barrier in our Regional Biocontainment Lab like all other B. pseudomallei strains). Following green fluorescent protein-labeled bacteria in lymph nodes during infection, it was clear the mouse reacts with a rather novel strong neutrophilic response to Bp82 along with antigen presenting cells. Two vaccinations with this Bp82 strain fully protected C57BL/6 mice from a normally deadly intranasal challenge with virulent B. pseudomallei. Instead of finding ~a million bacteria in the liver of infected animals as expected, vaccinated critters had zero, zilch, nada. Impressed yet? Well you know those MIP immunologists weren’t just going to stop there – they wanted to learn how the vaccine worked. Vaccinated animals showed a very strong IgG and IgM response against the bugs, with antibodies being primarily targeted to bacterial surface proteins. Based on three experiments, this humoral antibody response appeared to play a very important role in saving the vaccinated mice from certain death. Transfer of serum to naïve animals saved 38% from succumbing to the disease. Next, vaccinated CD4 and CD8 knockout mice were surprisingly protected from the disease, suggesting that T cell-independent antibodies play a key role. Finally, B cell deficient mice were significantly less well protected by vaccination than their wild type cage mates.
So why did we pick this paper for our coveted MIPublication of the Month®? First, the study implies that a safe and effective vaccine that can be delivered by a sub-cutaneous route may very well be in the cards for melioidosis in the not too distant future. That’s great news, particularly for those in endemic regions of the globe as well as folks trying to prop up the biodefense infrastructure of our country. Second, the study is a terrific example of that good olde MIP synergy with three separate labs coming together to share expertise to contribute to this fine piece of work. Finally, we’d like to see a vaccine developed against this bug before it mutates resistance to all available antibiotics. The folks at the MIPnews desk would hate to have to try to convince Dr. Schweizer not to name this possible novel super multidrug-resistant but inherently unstable killer bacteria “B. psupercalifragalisticexpimelioidosis”….

Ongoing/Upcoming Construction Project Notes
Micro A and B-Wing Roof Replacement Project – This project suffered numerous delays due to inclement weather but to everyone's relief the work was finally finished on Oct 25th.
Micro B-Wing Freezer Room Project – The work on the 4th floor is largely completed and equipment has been moved in. Work on the 3rd floor began this week and is estimated to take 6 weeks, finishing around the end of November and then the crew will move down to the 2nd floor with a goal of finishing the project around the first of the new year.
Micro A103 Grad Student Break Room Remodel – Work on the break room finished. Once the room is furnished it will be ready for use.
Project meetings for the Roof and Freezer Projects are held every Tuesday morning at 8:30am in Micro B124. Anyone who has questions about either project are encouraged to attend.

Local radio station K99's Good Morning Guys, Brian Gary, Susan Moore, and Todd Harding (Jenny Harding's husband), have been named small market personalities of the year by the Country Music Association.
Dr. Hoover recently had both knees replaced. The lab formally welcomed him back from his remarkably short absense, and as you can see several lab mates bit the bullet and had knee surgery in solidarity…
