Detecting Reporting Resistance in Fastidious Bacteria - SWACM

What commercial AST systems
might we use?
Etest or commercial broth microdilution MIC
system
– Perform test according to manufacturer’s
recommendations; use manufacturer’s QC ranges
For Etest - check technical information and
references
– Etest lists some breakpoints for M45 organisms, some
of which differ from those of CLSI
Note: the extent to which commercial systems have been
evaluated for most M45-A2 organisms is very limited
CLSI does not endorse commercial test systems
