Clear, quick results in as little as 18 hours!

HardyCHROM™ ESBL is a selective and differential chromogenic medium which is intended for the qualitative and presumptive detection from stool specimens of: 1) Enterobacteriaceae that are potentially non-susceptible to ceftazidime and cefpodoxime; and 2) Extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli, Klebsiella pneumoniae and Klebsiella oxytoca.

ESBL or Extended Spectrum Beta Lactamases refer to a group of enzymes produced by some species of bacteria that can mediate the organism’s resistance to one or more broad spectrum penicillins and cephalosporin antibiotics. Hardy Diagnostics is proud to offer this breakthrough culture media that will help screen ESBL quickly and more efficiently from stool specimen.
