Reagent and kit for detecting bacteria producing ESBLs (extended-spectrum beta-lactamase)

The invention discloses a reagent for detecting bacteria producing ESBLs (extended-spectrum beta-lactamase). The reagent contains components as follows: casein tryptone, yeast extract powder, beef extract powder, NaCl, 3-morpholinopropanesulfonic acid, sodium pyruvate, potassium nitrate, trehalose, phenol red, methylene blue, nystatin, bile salt from ox, vancomycin and the like. In order to facilitate detection, the reagent is applied to a kit for detecting the bacteria producing ESBLs. The bacteria producing ESBLs in a sample can be directly detected by the detection reagent which is preparedscientifically, and the reagent cost is low; a casset is coated with special substrates, growth factors and inhibitors, the bacteria producing ESBLs grow specifically, so that the bacteria producingESBLs are detected in time, scientific and effective guidance is provided clinically, and the reagent has important value for preventing and controlling hospital-acquired infection; besides, a detection result just needs visua
