In this blog post, I discuss our Summer Research Program's "Lab Themed Dessert" competion, for which one of my students created a cake "sculpture" of Bdellovibrio attacking and invading E. coli. It was tasty, informative, and fun! My student clearly thought about Bdellovibrio a LOT during the ... Read More
Over the past 30 years, the combined efforts of scientists and clinicians have delivered remarkable successes in HIV therapeutics. Since 1987, the FDA has approved more than 30 antiviral drugs, including 12 HIV protease inhibitors and one integrase inhibitor. These drugs stop ~99% of viral repli... Read More

Microbes are everywhere; they live in us and on us. They can't be seen with our naked eyes, thus we tent to neglect that they're there or even existed. Some microbes are harmful and some are not. However, we must learn to avoid contaminating sterile media and materials with these microbes. In th... Read More

Three organisms inoculated onto blood agar, straight line inoculation, to demonstrate hemolysis. From top to bottom:
Streptococcus pyogenes: beta, complete lysis of red blood cells, clear area around colony growth.
Streptococcus bovis: alpha, incomplete lysis of red blood cells, green area ... Read More
Search and destroy! This image shows us how an immune cell, called a macrophage, attacks foreign bodies like bacteria – or this microbead – completely engulfing it so it can be broken down deep within the cell.

The Lyme disease spirochete, Borrelia burgdorferi, is an obligate parasite that cycles between ticks and vertebrate hosts. B. burgdorferi alters the proteins expressed on its outer surface, depending on the state of each host. Here, we used immunofluorescent antibodies to identify spirochetes th... Read More
Bacteria adjust to wide fluctuations in food supply by controlling how big they get and how often they divide. Scientists at Washington University in St. Louis have just worked out the control system E. coli use to delay division so they can bulk up when food suddently becomes abundant. What can... Read More
