Ceftazidime/Clavulanic Acid 30/10 µg ESBL Detection Disc

The Ceftazidime/Clavulanic Acid 30/10 µg Disc is a combination antimicrobial susceptibility disc used in clinical microbiology laboratories for the phenotypic confirmation of Extended-Spectrum Beta-Lactamase (ESBL) production in appropriate Gram-negative bacterial isolates. Each disc contains 30 µg of ceftazidime plus 10 µg of clavulanic acid. It is typically tested alongside a ceftazidime 30 µg disc on Mueller-Hinton agar. A larger inhibition zone around the ceftazidime/clavulanic acid disc compared with ceftazidime alone can indicate clavulanate-mediated inhibition of ESBL activity. A difference of 5 mm or more is commonly used as a confirmatory criterion in established methods. The product is intended for in-vitro diagnostic and professional microbiology laboratory use.
