Carmen Gu Liu (Baylor College of Medicine) and colleagues published a new preprint on phage-antibiotic synergy. They've created a comprehensive method for evaluating synergism, additivism, and antagonism for all antibiotic classes, (they're calling it "synography"). They found that phage-antibiotic synergy is dependent on antibacterial mechanism of action, leads to reduced phage resistance emergence, is driven by phage burst size, and can be suppressed by serum and urine.
