Enzymes in these formulations attack proteins that make up a large portion of common soil (e.g., blood, pus). When CRE is introduced to other body systems, as might occur through improperly cleaned surgical instruments, catheters, or endoscopes, aggressive infections can occur.

An in-use test can determine whether an actively used solution of disinfectant in a clinical setting is microbially contaminated (Figure \(\PageIndex{5}\)). A phenol coefficient of 1.0 means that the chemical agent has about the same level of effectiveness as phenol.

Historically, the effectiveness of a chemical disinfectant was compared with that of phenol at killing. The MIC assay can also be performed using 96-well microdilution trays, which allow for the use of small volumes and automated dispensing devices, as well as the testing of multiple antimicrobials and/or microorganisms in one tray (Figure \(\PageIndex{3}\)). Carbapenem-resistant Enterobacteriaceae infections due to contaminated endoscopes have become a high-profile problem in recent years.
