CMMC Antibiotic Susceptibility Report

Supplemental Antibiotic Information

  1. Other antibiotic sensitivities are available by special request through the microbiology lab.

  2. Pseudomonas, Enterobacter, Serratia and Acinetobacter have inducible betalactamases and may develop resistance while on monotherapy with beta-lactam antibiotics.

  3. Pneumococcus is developing significant resistance to penicillin, it is no longer the drug of empiric choice for serious infections like sepsis and meningitis.

  4. When starting empiric therapy for meningitis (age 1month-adult) vancomycin and dexamethasone are now recommended. Dexamethasone should be administered before the first antibiotic dose.

  5. When obtaining deep tissue, abscess or bone for culture be sure to send the specimen to the lab in a non-formalinized, sterile container.   Pieces of tissue and bone are always better microbiologic specimens than swabs.

  6. Rifampin should never be used as monotherapy. Always use rifampin  in combination with other anti-infective agents.

  7. Suspected bacterial meningitis patients should receive antibiotic within 30 minutes of reaching the medical care system.

  8. Patients with resistant organisms (i.e.  MRSA, VRE) require special isolation. Please call Infection Control (x2892) and refer to the infection control manual.

  9. MRSA and methicillin resistant coagulase negative staphylocci should be considered resistant to all currently available B-lactam antibiotics.

  10. Combination therapy of penicillin, ampicillin or vancomycin, plus an aminoglycoside, is usually indicated for serious enterococcal infections, such as endocarditis. 

  11. For surgical prophylaxis, antibiotics should be administered within one hour of incision.
