Researchers in Dr. Eric Stabb's lab use bacterial genetics to study the light-organ symbiosis between the bioluminescent bacterium Vibrio fischeriand the squid Euprymna scolopes, as a model for natural bacteria-animal interactions. E. scolopeshatchlings lack V. fischeri, which they must obtain from their surroundings. After infection, the squid carry V. fischeri, and only V. fischeri, in epithelium-lined crypts of a specialized light-emitting organ. Several features make this symbiosis uniquely tractable. Notably, this natural infection can be reconstituted in the lab, so we are able to observe the bacteria and their gene expression in an ecologically relevant context inside its host.
The Stabb lab also aims to be involved in outreach efforts and spread the word of the power of microbes and the wonders of bioluminescence. Three Stabb labbers [Noreen Lyell, Richard M. (Mark) Jones, and Julie Stoudenmire] earned the prestigious Excellence in Teaching Award while the lab was at UGA, and we hope to continue producing excellent students and educators here at UIC. |
