To read this antibiogram:

  1. Each organism is presented with the susceptibility in percent to that antibiotic and the number of isolates tested for that specific antibiotic.
  2. Susceptibility greater than or equal to 90% is highlighted in light GREEN, 60%-89% in YELLOW, and less than 60% in RED.
  3. Nitrofurantoin is tested for urine specimens only.
  4. The susceptibility result for Streptococcus pneumoniae is a combination of screening test and E-test results.
  5. CLSI performance standards for antimicrobial susceptibility testing were applied. CLSI stands for Clinical and Laboratory Standards Institute (Formerly NCCLS, The National Committee for Clinical Laboratory Standards).
  6. Antibiotics not showing for an organism represent that susceptibility testing for that specific organism is not recommended or complete testing data was not available or number is too small for a valid reporting.
