Fosfomycin susceptibility testing is a challenge for laboratories. The testing intricacies for fosfomycin are discussed.

Taxonomic splitting of bacterial species can change AST recommendation. What should clinical microbiologists do when new species are assigned to the Enterobacteriaceae or when species are renamed? Romney Humphries addresses this problem in this week's Bugs & Drugs.

How does one interpret an MIC if there is no clinical breakpoint for the tested drug/bug combination? Some tools, including the epidemiological cut-off value and PK/PD breakpoints can help!

The ever-changing CLSI recommendations for colistin testing (and one lab director’s endless frustration with this!) are reviewed.

Have you ever encountered an isolate of Staphylococcus that gave you seemingly discordant susceptibility results? You'd be lying if you said "no"! Learn how your lab can sort out staphylococcal susceptibility testing dilemmas.
