ASM Topic Map
ASM calls your attention to a feature on its website called the “Topic Map” which appears at the top of ASM’s homepage. The Topic Map is a navigational tool that lets you select from a list of topics, including Clinical Microbiology, and see all the pages that are associated with that topic. Go to the ASM Web Pageand click on the Topic Map at the top of your computer screen. A pulldown menu will appear, allowing you to pick topics from the following list: All Topics, Biodefense, Clinical Microbiology, Postdoc Fellows, and Student Programs. Once you select the topic of interest, click “GO” and the list of related web pages will appear.
New from ASM Press: Cumitech 42
Cumitech 42: Infections in Hemopoietic Stem Cell Transplant Recipients (Coordinating Editor: Allan L. Truant), focuses on infectious complications frequently encountered in hemopoietic stem cell transplantation (HSCT) recipients. Guidelines for preventing opportunistic infections among HSCT recipients by the CDC, IDSA, and the American Society of Blood and Marrow Transplantation provide a solid foundation for this review. Infections are broken down into four main categories, including bacterial, viral, mycotic, and parasitic infections, and focus on those agents that occur at an increased rate among HSCT recipients in comparison to the general population.
New Academy Reports
A new report, “Microbial Triggers of Chronic Human Illness” released by the American Academy of Microbiology, details how the increasing aging populations in the United States and throughout the developed world appear to correlate with a switch from acute infectious diseases to chronic diseases, as the major cause of morbidity and mortality. The report also recommends new criteria be developed for evaluating the strength of association between microbes and chronic illness.
The recently released American Academy of Microbiology report, “Preharvest Food Safety and Security,” points out that recent outbreaks of a number of foodborne illnesses have been linked to contamination occurring in the preharvest stage of food processing. Recommendations are made for creating an accessible international database of genetic sequences for known foodborne pathogens along with new and improved tools for detecting and cataloging pathogens on the farm.
“From Outside to Inside: Environmental Microorganisms as Human Pathogens,” a new report released by the American Academy of Microbiology, points out the issue that while many infectious diseases are caused by human-to-human transmission, others are caused by microorganisms that exist in the outside environment. The difference between the two is the ability for environmental pathogens to survive and thrive outside the host. The report recommends that scientists from different fields work together to address the challenges presented by these environmental pathogens.

Light May Rapidly and Painlessly Kill Bacteria That Cause Gum Disease
Exposure to broadband light may provide a rapid and painless method for killing the bacteria that cause plaque and periodontal disease, say researchers from Texas and Massachusetts. Their findings appear in the April 2005 issue of the journal, Antimicrobial Agents and Chemotherapy. (N.S. Soukos, S. Som, A.D. Abernethy, K. Ruggiero, J. Dunham, C. Lee, A.G. Doukas, J.M.

Norovirus Prevalent in Those Suffering from Traveler’s Diarrhea
Norovirus may be the most common cause of travelers’ diarrhea for United States citizens returning from Mexico and Guatamala say researchers from the U.S., Guatemala, Mexico and Sweden. Their findings appear in the March 2005 issue of the Journal of Clinical Microbiology. (A.R. Chapin, C.M. Carpenter, W.C. Dudley, L.C. Gibson, R. Pratdesaba, O. Torres, D. Sanchez, J. Belkind-Gerson, I. Nyquist, A. Karnell, B. Gustafsson, J.L. Halpern, A.L. Bourgeois, K.J. Schwab. 2005.
