Pregunta 1

Pregunta
What are four characteristics of penicillins?
Respuesta
  • - strong gram negative coverage - strengthens D-ala/D-ala of the bacterial cell wall - decreased hypersensitivity reactions - binds to transpeptidases
  • - sensitive to beta lactamases - poor gram negative coverage - decreased risk of hypersensitivity reactions - detaches from transpeptidases
  • - sensitive to beta lactamases - poor gram negative coverage - binds to transpeptidases - increased risk of hypersensitivity reactions
