Potential Regulation Of Deadly Water-Borne Shigella Bacteria Pathogenesis Through The Shigella Infection Protein Spa47, Jamie Kingsford

Research on Capitol Hill

• Shigella is a gram-negative, bacterial pathogen typically found in contaminated water sources.
• Each year, Shigella is responsible for over 90 million infections and 100,000 deaths stemming from symptoms of severe dysentery, fever, nausea and vomiting.
• A needle-like apparatus found on the surface of Shigella allows the bacterium to infect host cells.
• Each needle-apparatus has an associated ATPase, a protein that can hydrolyze ATP into ADP and P_i.
• The Shigella needle-apparatus ATPase Spa47 is predicted to provide the energy for infection.
• Spa47 has been shown to be essential for infection – without Spa47, no infection will occur.
• We were …
