Which mechanism best describes how bacitracin interferes with bacterial cell wall synthesis?
Isoniazid's primary bactericidal activity against Mycobacterium tuberculosis is due to inhibition of which biosynthetic pathway?
A researcher finds a resistant S. aureus strain that carries a plasmid encoding a new vanA-like operon. Based on known mechanisms, what specific biochemical change should they look for to explain high-level vancomycin resistance?
Design a laboratory assay to distinguish whether an unknown antibiotic that inhibits bacterial growth acts like a beta-lactam or like vancomycin/bacitracin. Which of the following experimental approaches best differentiates these mechanisms?
