Carbapenem-resistant Enterobacteriaceae (CRE) "Hi Ross, As a gram negative bacillus, we can kill all its relatives including Klebsiella and E coli which are both considered as examples of Enterobacteriaceae. In fact, these bacteria are among the easiest for our system to eliminate in that when we produce a 6 log kill with MRSA we are usually looking at a 7 log kill for these bacteria."
