MAST Gentamicin 120 µg Antibiotic Susceptibility Discs – 250 Discs

MAST Gentamicin 120 µg Antibiotic Susceptibility Discs are high-potency diagnostic laboratory discs designed for detecting high-level gentamicin resistance in appropriate bacterial isolates, particularly Enterococcus species, using the agar disc diffusion method. Each disc contains 120 micrograms of gentamicin, an aminoglycoside antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit. Unlike conventional Gentamicin 10 µg susceptibility discs, the 120 µg formulation is used primarily for high-level aminoglycoside resistance testing. This helps clinical microbiology laboratories assess whether high-level gentamicin resistance is present in enterococci, which can affect the potential for synergistic activity with certain cell-wall-active antibiotics. Manufactured by MAST Group under the MASTDISCS range, these antibiotic-impregnated discs are designed to deliver consistent antibiotic potency and reproducible inhibition zone measurements when used with validated laboratory procedures. Each pack contains five cartridges of 50 discs, providing 250 discs for hospital microbiology laboratories, diagnostic centres, infectious disease laboratories and research institutions.
