CDC has reported a case of NDM-containing CRE K. pneumoniae isolated from a wound specimen of a woman in her 70s who had returned to the US after a log visit to India. She also reported prior visits with multiple hospitalizations in India. The isolate was resistant to the 26 antibiotics tested, including all aminoglycosides and polymyxins (despite being MCR-1 negative), while it was intermediately resistant to tigecycline. The fosfomycin MIC was 16 μg/mL. Unfortunately, the patient developed sepsis and died. Fortunately, the patient had been isolated and screening revealed no evidence of transmission.
CDC offered three take home points: (1) Most CRE remains susceptible to at least one aminoglycoside or tigecycline (2) When patients with this highly resistant organisms are identified, they should be placed under contact precautions* and (3) Facilities should obtain travel histories and consider screening for CRE if patients are from high-risk areas.
*Note: nice to see that somebody still loves contact precautions.
