low that you've practiced using the Kirby Bauer chart to interpret zones of inhibition, it's time to consider whether there are any patterns to the susceptibility and
esistance results we got with our class data set. You may find it useful to review the information covered on the following pages: More about our Antibiotics, Gram t
an indication of other bacterial characteristics.
Here are the standardized antibiotic test results for several lab sections.

Gram-negative genera used (listed first): Escherichia, Pseudomonas, Serratia.
Gram-positive genera used (listed last): Bacullus, Staphylococcus, Enterococcus.
There was no class data for the response of E. faecalis to Bacitracin.
Antibiotic abbreviations: AmC is amoxicillin/clavulanic acid, AM in ampicillin, B is bacitracin, CIP is ciprofloxacin, E is erythromycin, K is kanamycin,
NB is novobiocin, SXT is trimethoprim/sulfamethoxazole, and Va is vancomycin.
