A new selective broth enrichment automated method for detection of carbapenem-resistant Enterobacteriaceae from rectal swabs.

We evaluated the performance of an automated, rapid (TAT 4-8 h), liquid-culture method for carbapenem-resistant Enterobacteriaceae (CRE) detection from rectal swabs, in a setting of KPC-producing Klebsiella pneumoniae endemicity. With 600 samples (22 positive for CRE, 3.7%), the system sensitivity and specificity, at 8 h, were 100% and 99.
