What disk do we use to test for Penicillin Susceptibility?
Oxacillin
Penicillin
SXT
Bacitracin
If zone size for penicillin susceptibility falls out of range , what do we do next?
Penicillin MIC
Try another disk
MAC
Report as resistant
What is the definition of Breakpoint?
point where effective tissue concentration can be achieved by bacterial inhibition
point where effective tissue density can be achieved by bacterial inhibition
point where effective tissue concentration can be achieved by parasitic inhibition
point where effective tissue density can be achieved by parasitic inhibition
Breakpoint MIC panels use how many dilutions?
1
2
3
4
What is(are) the dilution(s) that need to be done?
one dilution above the break point
one dilution below the break point
In breakpoint MIC, how many wells are involved?
If the well(s) are not turbid , report as:
susceptible
immediate
resistant
repeat the test
If well(s) are turbid, report as:
susceptbile
intermediate
