MAST Ceftazidime-Avibactam 30-20 µg Antibiotic Susceptibility Discs – 250 Discs

MAST Ceftazidime/Avibactam 30/20 µg Antibiotic Susceptibility Discs are high-quality diagnostic laboratory discs designed to determine the susceptibility of bacterial isolates to the combination of ceftazidime and avibactam using the agar disc diffusion method. Each disc contains 30 micrograms of ceftazidime and 20 micrograms of avibactam. Ceftazidime is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis, while avibactam is a non-beta-lactam beta-lactamase inhibitor that protects ceftazidime against degradation by certain bacterial enzymes. Manufactured by MAST Group under the MASTDISCS range, these discs support antimicrobial susceptibility testing of clinically important Gram-negative bacteria, including certain multidrug-resistant Enterobacterales and Pseudomonas aeruginosa isolates. The discs are manufactured to provide consistent antibiotic potency and reproducible inhibition zone measurements when used with validated laboratory procedures. Each pack contains five cartridges of 50 discs, providing a total of 250 discs for hospital microbiology laboratories, diagnostic centres, infectious disease laboratories and research institutions.
