The Tale of an Ancient Ally: Phage Therapy, Part II

By Jesus Diaz, MD

February 22nd, 2024

Dr. Diaz Vera, Infectious Diseases Fellow at the University of South Florida Division of Infectious Diseases, presents a companion lecture to his original talk on bacteriophage therapy. Because of the rising tide of antimicrobial resistance, many experts believe that we are entering the post-antibiotic era in medicine. As a result, researchers are exploring phage-antimicrobial synergy in an attempt to make our antibiotic armamentarium go farther. Dr. Diaz elaborates on the application of phage-antimicrobial synergy and provides examples of phage therapy utilized in the clinical setting.

Nocardia and Actinomycosis

By Richard L. Oehler, MD

January 19th, 2024

Dr. Richard Oehler, Professor of Medicine at the Division of Infectious Diseases and International Medicine, Morsani College of Medicine at USF, presents this overview of Nocardia and Actinomyces, two closely-related gram positive filamentous rods which have distinct differences. In his presentation, Dr. Oehler initially covers Nocardiosis, followed by Actinomycosis, and compares and contrasts both and how they produce human infection. Topics covered for both infections include their taxonomy, epidemiology, types of patients infected, infectious syndromes, potential complications, recommended therapies, and duration of treatment.
