RESEARCH
The Duerkop lab studies bacterial viruses (bacteriophages or phages) and their interactions with their hosts. The long-term goal of the Duerkop lab is to understand how phages and other forms of mobile DNA contribute to host-microbe interactions in the intestine and their overall impact on human health.
Our lab seeks to: 1) Determine the mechanisms underlying phage interactions with multidrug resistant enterococci and how phages impact enterococcal colonization of the intestine; 2) Understand how native CRISPR-Cas systems function as barriers to nucleic acid acquisition in the intestine and how CRISPR-Cas contributes to the genetic diversity and ecology of the microbiota; 3) Explore the role phage communities play in maintaining a healthy intestinal microbiota and assess whether intestinal phages can shape the composition of the microbiota leading to chronic intestinal inflammation.
