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


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

An audience Q&A follows the technical presentation.


Margaret Butler, Ph.D., Department Scientist, Nelson Laboratories Bozeman

Dr. Margaret “Maggie” Butler is Department Scientist for Nelson Laboratories Bozeman. She joined the company, then named BioScience Laboratories, in 2010 and has served in various roles including as Principal Scientist. Maggie has a Ph.D. in microbiology from the University of Montana and post-doctoral training in biochemistry and molecular biology from Dartmouth Medical School. She previously worked in the Cell Biology Department at Yale University School of Medicine and the University of Chicago School of Medicine, focusing on the structure and function of proteins involved in membrane trafficking and synaptic communication in both healthy and diseased tissues. Her research background on neuronal signaling mechanisms led to her keen interest in understanding the quorum sensing that occurs in the life cycle of biofilms.
