In vitro rapid diagnostic test for the detection of CTX-M-14 and CTX-M-15 β-lactamases in bacterial culture.
There are over 250 variants of CTX-M described. They are classified into 3 minor and 5 major families among which group 1 (whose major representative is CTX-M-15) and group 9 (whose major representatives are CTX-M-14 and CTX-M-27) are the main responsibility for the increase of ESBLs prevalence worldwide, whether in community or hospital settings.
