Drs. Nico Cortes-Penfield (@Cortes-Penfield), Kerry LaPlante (@Kerry_LaPlante), Jessica Seidelman (@JessieLSeidel) join Dr. Julie Ann Justo (@julie_justo) to discuss the pesky slime that is biofilm in periprosthetic joint infections. They review biofilm composition & development, have an honest discussion about whether antibiotics can ever really eradicate it, and provide updates on the promising non-pharmacologic strategies on the horizon (bacteriophages, electromagnetism, & more).
