Oxoid Quinupristin/Dalfopristin (QD) 15 µg Antibiotic Discs

Oxoid Quinupristin/Dalfopristin (QD) 15 µg Discs – Precise Antimicrobial Susceptibility Testing

Oxoid Quinupristin/Dalfopristin (QD) 15 µg Discs are high-quality antibiotic susceptibility test discs used for in vitro testing of Gram-positive bacterial isolates, particularly multi-drug resistant strains like Staphylococcus aureus and Enterococcus faecium. These discs are essential in clinical microbiology laboratories, research labs, and diagnostic facilities for accurate antimicrobial profiling.

What Are Oxoid Quinupristin/Dalfopristin (QD) 15 µg Discs?

Oxoid QD discs are filter-paper discs impregnated with 15 µg of the quinupristin/dalfopristin combination, a streptogramin antibiotic that works synergistically to inhibit bacterial protein synthesis. When used in disc diffusion tests, the discs produce zones of inhibition that indicate bacterial susceptibility, helping guide clinical treatment decisions and monitor antibiotic resistance trends.
