W.M. Keck Science Department Assistant Professor of Chemistry Ethan van Arnam co-authored a paper,Β ΜύΎ±²ΤΜύApplied and Environmental Biology, that explored how symbiotic bacteria help fungus-growing ants suppress fungal pathogens through the production of antifungal compounds. βAnimal hosts often benefit from chemical defenses provided by microbes,β the co-authors explain. βThese molecular defenses are a potential source of novel antibiotics and offer opportunities for understanding how antibiotics are used in ecological contexts with defined interspecies interactions.β
