• Mupirocin and Novobiocin Activity in Canine Staphylococci

  2026-08-13

  The reference study evaluated in vitro susceptibility to mupirocin and novobiocin across meticillin-susceptible and meticillin-resistant staphylococci from healthy dogs and dogs with superficial pyoderma. Its principal practical contribution is the organism- and resistance-stratified comparison, which supports targeted susceptibility testing rather than assuming that meticillin resistance predicts uniform resistance to non-β-lactam agents.

• IAA-Driven Ferroptosis in Rice Blast Conidia

  2026-08-13

  A 2026 Molecular Plant Pathology study identifies fungal-derived indole-3-acetic acid (IAA) as a regulator of developmental conidial death in Magnaporthe oryzae.
