2018 Antibiogram

Posted February 10, 2019

Updated antibiogram for 2018 is available online. Please call Micro or Dr. Hoskinson with specific questions.

Daptomycin for S. aureus is shown as being 100% susceptible in the antibiogram but that is because we only result susceptible isolates per CLSI. Anything that is considered “non-susceptible” is suppressed. So these are the numbers that we calculated including the “non-susceptible” strains.
S. aureus: Dapto susceptible 87%
MRSA: Dapto susceptible 90%
Pip/Tazo for pseudomonas is another that gets suppressed so these are the numbers that we calculated
P. aeruginosa: pip/tazo susceptible 88%

Gram Positives 2018. *=Not tested/Suppressed Please NOTE: Isolates less than 30 should be interpreted with caution as there are insufficient numbers to give a ideal susceptibility antibiogram. Dapto on Staph aureus and MRSA are for MIC only.
Gram Negatives 2018. *=Not Tested/Suppressed Please NOTE: Isolates less than 30 should be interpreted with caution as there are insufficient numbers to give a ideal susceptibility antibiogram. ***= P.aeruginosa has a MIC of 99% susceptible; however, few resistant strains tested by KB method, show a susceptibility of 50% for TZP.
