This image depicts rows of cuvettes containing the bacterial human pathogen, Shigella flexneri, which annually causes 165 million cases of severe dysentery worldwide. Here, Shigella has been grown in a solution that closely resembles the protein content of human cells and will change color in response to pH. While initially red, the solution transforms into a bright pink color due to acidic by-products produced during Shigella growth. My research focuses on how virulence genes in Shigella are controlled. In doing so, I hope that my findings can be used to develop novel therapeutics and/or a more effective live-attenuated Shigella vaccine.
