AI vs. Superbugs: Artificial Intelligence and the Search for New Antibiotics
The specter of antibiotic-resistant bacteria looms large in our society. In two presentations we delve into AI-assisted research into antibiotic drug development. We will explore the latest research using AI to search the human genome for microbe-fighting peptides, as well as using AI as a novel approach to testing the susceptibility of antibiotics.
AI for Antibiotic Discovery

University of Pennsylvania
Computers can be programmed for superhuman pattern recognition of images and text; however, their application in biology and medicine is still in its infancy. César de la Fuente will review advances over the past half decade, which are accelerating discoveries in the crucial and underinvested area of antibiotic discovery. His lab developed the first antibiotic designed by a computer with proven efficacy in preclinical animal models, demonstrating that machines and artificial intelligence (AI) could be used to design therapeutic molecules. These algorithms have accelerated antibiotic discovery and, for the first time, were able to successfully mine the human proteome for antibiotics. Recently, de la Fuente and his lab expanded the proteome-mining efforts to explore the proteomes of extinct species. Using AI, they discovered the first therapeutic molecules in extinct organisms, including Neanderthals and Denisovans, launching the field of molecular de-extinction. Their efforts have dramatically reduced the time needed to discover preclinical antibiotic candidates from years to hours. De la Fuente will discuss his belief that we are on the cusp of a new era in science where advances enabled by AI will help control antibiotic resistance, infectious disease outbreaks, and pandemics.
People Aren’t Petri Plates: Why Antibiotics Fail
Michael J. Mahan
Professor of Microbiology

University of California, Santa Barbara
Accurate assessment of antibiotic susceptibility is critical for the identification of existing agents for the treatment of antimicrobial resistant (AMR) infections. Here we examined whether antimicrobial susceptibility testing (AST) in media that are more physiologically representative of in vivo infection conditions could improve prediction of clinical outcome. This analysis identified several FDA-approved antibiotics for the treatment of AMR infections that standard AST failed to identify; and also identified antibiotics that were ineffective despite indicated use by standard AST. Clinical implementation of test methods with increased diagnostic accuracy would help mitigate the imminent AMR crisis via utilization of existing agents and optimization of drug discovery and development.
