For her senior project, Alessia Zambrano characterized biofilms produced by a bacterium Janthinobacterium lividum: a strain isolated from the Hudson River Valley area that plays an essential role in aquatic health and community diversity. Alessia took three-dimensional images of the biofilm using an atomic force microscope. These 3D reconstructions for the first time provide a detailed picture of the shape, size, and surface topography of individual cells of this bacterial strain.
Batrachochytrium dendrobatidis (Bd) is a deadly pathogen of many species of amphibians. One of the most promising ways to combat its spread is to expose Bd zoospores to a purple pigment, violacein, which can kill Bd. Working with Professor Brooke Jude, Abby Soussan is determining whether Bd zoospores can sense and move away from the pigment, which would seriously inhibit the effectiveness of this potential treatment.
For her senior project, Yuanyuan Gao is asking whether infection with Borrelia burgdorferi, the bacterium that causes Lyme disease, affects the behavior of white-footed mice, Peromyscus leucopus, which are common hosts for the bacterium. In the lab at the Cary Institute of Ecosystem Studies in Millbrook, NY, Yuanyuan is comparing the activity levels of wild mice that have been vaccinated against B. burdorgeri to the activity levels of mice that have not.
The Summer Research Poster Session happened in RKC on Sep 24. Students presented results of their summer projects, both from the Bard Summer Research Institute (BSRI) program, and from various external research internships. About eighty people attended the session, which was quite a crowd for this late hour, and some incredibly interesting conversations happened at the posters.
