Virginia Tech Researchers Discover How Bacteria Cause Dysentery
Researchers at Virginia Tech, led by Daniel Capelluto, have uncovered how the bacterium Shigella flexneri, which causes dysentery, manipulates molecules to infect its host. This discovery, published in the journal Structure, reveals that bacterial proteins disrupt the host’s metabolism, creating an acidic environment that aids bacterial survival.
Understanding the Infection Process
Capelluto and his team found that Shigella flexneri releases proteins that disrupt the host’s cellular balance, causing an acidic environment and producing excess lipids. These conditions help the bacteria survive and continue their infection cycle.
Impact on Global Health
Dysentery, caused by Shigella flexneri, is prevalent in low- and middle-income countries, especially among children under 5 years old, and is responsible for 160,000 deaths worldwide each year. Understanding this bacterial mechanism could lead to better preventive measures against such infections.
Future Implications
This research could serve as a foundation for understanding the molecular mechanisms underlying various bacterial infections, potentially leading to more effective treatments and preventive strategies.
