Summary of "Detection of carbapenemase-producing Enterobacterales and the BD Phoenix CPO Detect panel."

: Treatment options for infections with carbapenem-resistant Enterobacterales are strongly limited. New antimicrobials are not effective against all types of carbapenemases. Therefore, rapid and reliable antimicrobial susceptibility testing and identification of the resistance mechanism are important. : We assess several methods to determine carbapenemase production of Enterobacterales in culture and discuss the value of the novel automated BD Phoenix CPO Detect (BDPCPO) panel for the detection and classification of carbapenemases. : The meropenem-MIC range used in the BDPCPO panel includes the EUCAST screening breakpoint for the detection of carbapenemase producers. The phenotypic, inhibitor-based assay for detection of carbapenemase activity in the BDPCPO panel displays high sensitivity for carbapenemase detection while its specificity is modest. Therefore, confirmation testing of positive results is warranted. Nevertheless, implementing the BDPCPO panel has the potential to reduce time-to-result for detection and classification of carbapenemase producers.

Medical and Biotech [MESH] Definitions

Hemagglutination test in which Coombs' reagent (antiglobulin, or anti-human globulin rabbit immune serum) is added to detect incomplete (non-agglutinating, univalent, blocking) antibodies coating erythrocytes. The direct test is applied to red cells which have been coated with antibody in vivo (e.g., in hemolytic disease of newborn, autoimmune hemolytic anemia, and transfusion reactions). The indirect test is applied to serum to detect the presence of antibody (e.g., in detection of incompatibility in cross-matching tests, detection and identification of irregular antibodies, and in detection of antibodies not identifiable by other means).

The ability to detect sharp boundaries (stimuli) and to detect slight changes in luminance at regions without distinct contours. Psychophysical measurements of this visual function are used to evaluate visual acuity and to detect eye disease.

Detection of drugs that have been abused, overused, or misused, including legal and illegal drugs. Urine screening is the usual method of detection.

A deep blue dye (with the formula OC6H4NC6H4OH) used to detect AMMONIA in a common test called the Berthelot's reaction and to detect PARACETAMOL by spectrophotometry.

A test to detect non-agglutinating ANTIBODIES against ERYTHROCYTES by use of anti-antibodies (the Coombs' reagent.) The direct test is applied to freshly drawn blood to detect antibody bound to circulating red cells. The indirect test is applied to serum to detect the presence of antibodies that can bind to red blood cells.
