We are very pleased to announce that the in the fiscal year that ended June 30, 2012, the MIP Dept. once again had an outstanding year in terms of extramural grant funding. MIP researchers brought in a whopping $33,069,964 through 158 grant awards according to the CSU Sponsored Programs database. That’s $1.2 million more than last year – and currently MIP officially has 265 actively funded grant projects with a total value on the books of over $144 million. In case you need perspective on what 33 million looks like, that’s the same number of Americans that are predicted by AAA to hit the road this Labor Day weekend……. Congratulations to Britta Wood for being accepted to the NIH Graduate Student Research Conference being held on October 9 & 10 on the main NIH campus in Bethesda, MD. The conference will introduce 120 advanced graduate students to the ins and outs of the Intramural Research Program. Carol Wilusz was named to the Editorial Board of PLoS ONE. PLoS One is currently the largest scientific journal in the world, publishing over 1500 articles per month. Congratulations Carol! MARK YOUR CALENDARS! Dr. Gerry Callahan has a new book coming out in Spring 2013 entitled, "Lousy Sex: A marriage of art and science". The title has to do with the bacterial infection that kills all male lice and results in female louse asexual reproduction. The cover for his upcoming book will likely be modeled after this New Yorker cover... Microbiology Room B120 has been spruced-up with a fresh coat of paint, new carpet, and stackable chairs. Congratulations to Ian Orme and colleagues for having their recent paper on the virulence of the Beijing sublineage of M.tb appear in the ‘Journal Highlights’ section of the August edition of Microbe – the news magazine of the American Society for Microbiology.

Identification of a novel antiviral inhibitor of the flavivirus guanylyltransferase enzyme Hilary Stahla-Beek, Daniel April, Bejan Saeedi, Amanda Hannah, Susan Keenan and Brian Geiss Journal of Virology 86: 8730-8739 (August 2012) While many folks today really like caps and are debating which looks cooler – flat billed or old-school curve-billed ones, the labs of Brian Geiss and Susan Keenan (UNC-Greeley) are avid cap haters. They want to stop the manufacturer of such things because they feel that caps contribute significantly to the hooligan-esque behavior of lowly life forms. But before you hide your baseball cap to avoid being labeled by Brian as such (if you haven’t already burned your baseball cap due to the recent poor play of our local team), please be advised that the caps Brian and Susan are focused on are a part of messenger RNAs made by a group of viruses that include problematic pathogens such as dengue and West Nile virus. If you can keep the cap off of the 5’ end of the viral mRNAs, you should block the translation of viral proteins and destabilize viral mRNAs. In effect, you’ll stop the virus right in its tracks before it can even get started. Given the recent burst in West Nile virus around the country and the two billion people at risk for dengue virus infection, prospects for an effective antiviral against these agents will obviously be greeted with much interest. To inhibit flaviviral mRNA capping, Brian/Susan et al took a fairly straightforward approach. They prepared recombinant dengue virus capping enzyme and screened over 235,000 compounds at a Harvard Medical School facility to find small molecules that would displace GTP (the donor moiety of the mRNA cap) from the active site of the enzyme. They found 222 compounds that may indeed do this in their high throughput screening assay and decided to follow up one class of compounds in depth. These 2-thioxothiazolidine-4-one based compounds inhibited the dengue virus capping enzyme at micro molar concentrations and showed activity at similar concentrations against dengue virus, West Nile virus, and yellow fever virus in tissue culture cells. They selected a favorite chemical moiety from the structure-activity relationship analyses they have performed to date and are currently putting this through a battery of tests/development efforts to optimize the compound and perhaps down the road identify a new, broad-spectrum anti-flavivirus drug. So why did we pick this study as our coveted MIPub of the Month® for August over some pretty tough competition (e.g. a study by Neff et al in Genome Research that reveals a bunch of cool things about induced pluripotent stem cells, work by Kato-Maeda et al on M. tb sublineage-specific pathogenicity that was highlighted in Microbe)? Why there were three reasons (of course!). First, in an era where we appreciate that monotherapy against most if not all viruses is ultimately useless for drugs that target pathogen-specific factors, increasing the number of drug candidates in the pipeline is vital. Second, the study highlights a successful collaboration with our university neighbor to the southeast combining informatics with biochemistry/virology. Third – the headlines this month regarding the current outbreak of West Nile virus are alarming to say the least. Let’s hope the project spews out a ‘Geiss-er’ of drug candidates against this emerging scourge. MIP Publications Late July & August 2012 Veselinovic M, Preston Neff C, Mulder LR, Akkina R.

The Fall 2012 Department Seminars began on August 14th with Dr. Randy Basaraba's seminar entitled, "The Toxic Truth about Sugar in the Pathogenesis of TB/Diabetes Comorbidity". Be sure to check out the Seminar Schedule so you do not to miss any exciting presentations!
Clinton Dawson will be working in the Slayden Lab Bryna Fitzgerald will be working in the Belisle Lab Ben Krajacich will be working in the Foy Lab Linnell Randall joined the Schweizer Lab in January Amber Rico will be working in the Olson Lab "Where's Don Klein?" - The answer: off and away for the rest of the year, trying to finish a ten-year (so far) project by completing his microbial ecology book, plus working in the the lab of Ginny Edgcomb at WHOI (studying protozoa that thrive in hypoxic environments at the bottom of the Mediterrean). In his spare time, still writing letters concerning word usage in microbial ecology, chasing clams and watching the sun go down over Buzzards Bay. MIP'ers of the Zabel Lab reached new heights this summer when they summitted Grays and Torreys Peaks... Brian Foy, Massamba Sylla, Ben Krajacich, and Doug Brackney have been hanging out in Senegal this summer doing fieldwork. The gang is working on two projects: an NIH-funded study concerning the effectiveness of ivermectin for malaria control and a CSU- IDSC pilot project involving some cutting-edge metagenomic hunting for arboviruses and other pathogens in human blood via capturing human-blood feeding mosquitoes. Massamba has of course been an excellent host while Ben, Doug and Brian have all finally made it through their bouts of 'Tourista', and are currently reeling in the data. Maddie Breer, Hannah Laurence, and Margaret Escobar went to Quito, Ecuador with Experiential Learning International (ELI). Maddie and Margaret brought The Little Shop of Physics and spent their time teaching physics and english to orphans. It was an incredible experience! Hannah spent her time at the University assisting the veterinary students with surgeries and other procedures. All three stayed with host families and had the opportunity to travel throughout Ecuador. They visited the Amazon to go white water rafting and got to see the giant tortoises in the Galapagos! It was definitely a summer well spent! Looking for a way to destress at the end of a long day? Join us for yoga! What: Free yoga! The class will be taught by Carol Borchert, a certified yoga instructor with 10 years of experience. She’ll be teaching a variety of styles, from flow yoga to restorative. This class is open to everyone – whether you have never done yoga before or are an experienced practitioner. Please bring a yoga mat and wear comfortable workout clothing. Sponsored by the Department of Microbiology, Immunology and Pathology. MARK YOUR CALENDARS! The annual Rocky Mountain Virology Club Meeting is scheduled for September 28-30 at Pingree Park Campus. The Keynote Speaker will be Dr. Luis Rodriguez, Research Leader, Foreign Animal Disease Research Unit, Plum Island Animal Disease Center. More information may be found at the Rocky Mountain Virology Club website The Fall meeting of the Rocky Mtn Branch of the American Society for Microbiology has been slated for October 19-20th at UNC-Greeley. Mark your calendars and stay tuned for more information on this great regional opportunity to present your research and network with colleagues. Best Wishes Kim! Best Wishes to Kim Mashek on her new position in CSU's College of Business. He last day with MIP was August 8th. We will miss her friendly face and helpful attitude. Congratulations to Greg Ebel and his wife Jen on the birth of their son, Ansel, born August 15th at 7 pounds 14 ozs. Both Mom and baby are doing great, Ansel is getting used to having three sisters. |

Q Fever Scores Novel Grant for Dr. Duncan A baby seal walks into Mulligan’s Bar and gets asked ‘what’ll it be’? The seal sighs deeply and says, ‘anything but Canadian Club on the Rocks’ While it may be over a 1,000 miles to reach the Pacific ocean from Fort Collins, trivial things like that did not stop an enterprising Canadian named Colleen Duncan from scoring a $100,000 grant from NOAA to study both the prevalence and the optimization of diagnostic strategies for Coxiella burnetii in Pacific marine mammals. C. burnetii causes ‘Q’ (no relationship to Quackenbush) Fever, a debilitating disease with potential biodefense implications that historically has not been looked for in marine mammals. So if you come across a sick seal while paddling across Horsetooth this weekend (or know any other bad seal jokes), give Colleen a call.
