Breakpoints

From generating 150 liters-worth of E. coli to the first X-ray crystallography of an ESBL, Drs. Robert Bonomo, Ryan Shields (@ryankshields), and Erin McCreary (@ErinMcCreary) take a deep dive into beta-lactamases like AmpCs, KPCs, and more.

Joining the discussion are Robert Bonomo, an expert on antibiotic resistance mechanisms, and Ryan Shields, a specialist in antibacterial treatment. They delve into the stealthy world of gram-negative bacteria, revealing how efflux pumps and porin mutations lead to significant resistance challenges. Their insights on beta-lactam inefficacy and the implications for clinical treatment are riveting. The duo emphasizes the urgent need for awareness and innovation in tackling these evolving bacterial threats to improve patient outcomes.

Pathogen-directed trials are among the most important trials that clinicians need to guide therapy but are also incredibly difficult to design and enroll. Rachel Britt (@RachelBPharmD) gets a behind-the-scenes interview with Adam Stewart (@adm_stewart), lead investigator of MERINO-2, and Jason Pogue (@jpogue1), lead investigator of OVERCOME. They discuss original intentions and evolving expectations to investigate optimal antibiotic therapy for multidrug resistant bacteria. Listen in for the insider analysis!
