What agents to test and which to avoid!

Occasionally colleagues request information from EUCAST on what agents to test and which to avoid. EUCAST has hitherto refrained from giving firm advice simply because national traditions, availability and cost of agents, and guidelines vary to the extent where a general prescriptive advice becomes inappropriate. "Read between the lines:"agents which EUCAST consider unsuitable for therapy of a species or a group of species will typically lack numerical breakpoints in EUCAST tables. Agents considered appropriate for some or several types of infection with the species (or group of species) will have numerical breakpoints. An "IE" is a subtle encouragement together with a reminder that EUCAST could not find evidence for the appropriateness of the agent, whereas a "dash" is firm recommendation from EUCAST to avoid the agent.
