Microbiology/Bacteriology: Community and motility behavior of bacteria
Joshua Shrout

Research Interests:

The Shrout Lab is interested to better understand how bacteria function in response to their environment. We are particularly interested in the "sociomicrobiology" and motility of bacteria where bacteria act at a community level. Bacterial community behavior is important to many different aspects of bacteria, including: survival, infection, symbiosis, elemental cycling, and pollutant degradation. We have relatively recently come to understand that surface-attached biofilms represent the dominant mode of bacterial growth. Thus, many studies of bacteria growing in test tubes cannot be translated to understand bacterial function in the “real world”. There are many biofilm-related global scale issues that pertain to 1) bacterial infections, 2) engineered water treatment, 3) corrosion of water distribution infrastructure, 4) hospital-acquired infections on medical devices (e.g., artificial joints, implants, catheters, etc.), and 5) biogeochemical cycling in nature. The Shrout Lab at Notre Dame seeks answers to these biofilm and bacterial community-associated problems by conducting fundamental research to understand cell-cell signaling and surface colonization of bacteria.

Most of this work is conducted using either Pseudomonas aeruginosa or Myxococcus xanthus. We use a variety of classic microbiology and molecular biology techniques in addition to microscopy and collaborate routinely with colleagues in Chemistry, Biology, and Applied Mathematics to discern bacterial community behavior.
