	Cefnitrothiophene is a widely used chromogenic cephalosporin substrate used for detecting the presence of bacteria β- Lactam enzyme. Also known as 6- (2-nitrophenyl-3 ', 5' - diphenylcarbamoyl-4 methyl-2-oxo-2H-pyran-3 carboxylic acid, it is a chromogenic cephalosporin substrate used for detection β- Lactam activity in bacteria.
 Cefnitrothiophene is widely used as a diagnostic tool in microbiology laboratories to detect the presence of clinically isolated bacteria β- Lactam enzyme, which can endow β- Resistance to lactam antibiotics such as penicillin and cephalosporin.
 In the β- In the presence of lactam, cefnidazole is bright yellow, making it a useful, cost-effective screening tool for rapid identification of antibiotic resistant bacteria. In addition, it is effective for detecting β- Lactam enzyme has high sensitivity and specificity, making it a valuable tool for monitoring emerging antibiotic resistance in clinical environment.
 
	Characteristics of Cefnitrothiophene
 1. High sensitivity: Cefnidazole against β- Lactam enzyme activity is highly sensitive, which means that it can even detect micro enzymes that may not be detected by other tests.
 2. Specificity: Cefnidazole is effective against β- The specificity of lactam enzyme means that it will not react with other enzymes or compounds that may exist in bacterial samples.
 3. Speed: Cefnidazole produces visible color changes within a few minutes after detection, making it a fast and effective identification method β- Methods of lactam enzyme activity.
 4. Cost-effective: Cefnidazole is relatively inexpensive and widely used, making it a cost-effective choice for laboratories.
 5. Multifunctionality: Cefnidazole can be used to detect various bacteria β- Lactam enzyme activity, including those that may affect β- Lactam antibiotic resistant bacteria.
 Overall, Cefnitrothiophene is used to detect bacteria β- Lactam enzyme activity is an important tool, which has many advantages compared with other detection methods.
