Medical Device Biofilms: Slimy, Sticky, Stubborn, and Serious

Published Date: September 21, 2022

Major advances in medical devices have been made over the last few decades, keeping thousands of people alive and improving the quality of life for others. At the same time, these devices (e.g., implants, catheters, in-dwelling devices, and contact lenses) can be the source of serious or life-threatening infections caused by the adherence and establishment of biofilms on the surface of the device.

Due to the unique nature of a biofilm’s structure and its resistance to antimicrobial agents, minimizing the risk of biofilm formation poses great challenges. This 60-minute Webinar will explore current perspectives on and testing methods of biofilms.

Topics include:

  • Current test methods to evaluate the efficacy of biofilm-control strategies
  • In-house case studies evaluating biofilm
  • Current industry and regulatory perspectives on biofilms.


A Q&A session follows the technical presentation.


Margaret (Maggie) Butler

Department Scientist, Nelson Labs Bozeman

Dr. Margaret (Maggie) Butler holds a Ph.D. degree in microbiology from the University of Montana, followed by post-doctoral training in biochemistry and molecular biology at Dartmouth Medical School. Her research experience includes 15 years in the Cell Biology department at Yale University School of Medicine and 4 years at the University of Chicago School of Medicine, where she focused on the structure and function of proteins involved in membrane trafficking and synaptic communication in both healthy and diseased tissues. Dr. Butler joined BioScience Laboratories (now Nelson Labs Bozeman) in 2010. She worked briefly in the Clinical Laboratory and the Quality Assurance Unit and was subsequently promoted to a principal scientist in 2012. Her currently role is Department Scientist, Nelson Labs Bozeman. Maggie's research background on neuronal signaling mechanisms led to her keen interest in understanding the quorum sensing that occurs in the life cycle of biofilms. She strives to provide high-quality service to clients and enjoys exploring new developments in the industry.


Russell Griggs

Principle Investigator II

Russell Griggs earned his B.A. from Middlebury College (Middlebury, VT) in 2010 with a major in molecular biology and biochemistry. He earned an M.S. in earth sciences from Montana State University (Bozeman, MT) in 2013 with a focus on low-temperature geochemistry and subglacial microbial processes. Russell has worked for Nelson Labs for 8 years with a focus on conducting clinical and in vitro testing of topical antiseptics.
