Clinical Significance
Carbapenem resistance among the Enterobacteriaceae is an emerging problem in the USA, especially on the east coast where several outbreaks have been reported. Classic screening procedures involving selective enrichments followed by traditional culture isolation step are labor intensive and turnaround time is slow. The use of selective and differential agar allows for rapid (24 hour) screening of specimens to identify the presence of carbapenem-resistant Enterobacteriaceae.
