Description

β-Lactamase production (ESBL, AmpC, carbapenemase) is the most common mechanism of β-lactam drug resistance in Gram negative bacteria. Each of the involved mechanisms can be plasmid-encoded and transfer horizontally. Moreover, plasmids continuously gather other antibiotic resistance determinants, ultimately closing to pan-resistance. Their spread leads to increased colonization pressure in hospital and community as well. It is crucial to ensure that proper surveillance is in place to help implement appropriate guidelines and policies for their spread control. Rapid detection of bacteria producing these enzymes also allows for de-escalation to more targeted therapy, to conserve carbapenem antibiotics for more serious infections. Intended Use : CHROMagar™ C3GR is a selective and differential chromogenic culture medium, intended for use in the qualitative direct detection of gastrointestinal colonization with 3rd generation cephalosporin-resistant Enterobacteria (C3GR-E) to aid in the prevention and control of C3GR-E in healthcare settings. The test is performed with rectal swab and stools from patients to screen for C3GR-E colonization. Results can be interpreted after 18-24 h of aerobic incubation at 35-37 °C. The medium can also be used as an early warning indicator for diagnostic tests of infections to signal the possible presence of multi drug-resistant bacteria. This use does not replace the institution’s protocols. CHROMagar™ C3GR is not intended to diagnose C3GR-E infection nor to guide nor monitor treatment for infections.
