Liofilchem® Nystatin Ny Antimicrobial Susceptibility Discs, 100 Iu, 250 Discs/Pack

Standardized Susceptibility Testing for Fungal Infections Using Kirby-Bauer Disc Diffusion Method

The Liofilchem® Nystatin Ny Antimicrobial Susceptibility Disc (100 IU) is a high-quality diagnostic tool used for fungal susceptibility testing in clinical and research laboratories. These pre-impregnated antibiotic discs are designed for quantitative antifungal susceptibility testing (AFST) against yeasts and fungi, particularly Candida spp. and other pathogenic fungi.

This disc is intended for use in the Kirby-Bauer disc diffusion method, which helps determine fungal resistance or susceptibility to Nystatin, a polyene antifungal agent that disrupts fungal cell membranes by binding to ergosterol. These discs comply with Clinical and Laboratory Standards Institute (CLSI) and EUCAST (European Committee on Antimicrobial Susceptibility Testing) guidelines, ensuring accurate and reproducible results in clinical microbiology laboratories.

How to Use the Liofilchem® Nystatin 100 IU Discs in the Kirby-Bauer Method

1️⃣ Prepare a standardized fungal inoculum (0.5 McFarland standard).

2️⃣ Evenly spread the fungal suspension onto Mueller-Hinton agar with glucose and methylene blue (MHA-GMB) or Sabouraud dextrose agar.

3️⃣ Place Nystatin Ny 100 IU discs onto the agar surface using sterile forceps or an automatic disc dispenser.

4️⃣ Incubate at 35 ± 2°C for 24–48 hours (conditions vary for different fungi).

5️⃣ Measure the zone of inhibition around the disc using a calibrated ruler or automated zone reader.

6️⃣ Compare results with CLSI or EUCAST breakpoints to determine susceptibility or resistance.

Interpretation of Results (CLSI/EUCAST Guidelines)

(Values may be updated based on CLSI/EUCAST guidelines; always refer to the latest breakpoint tables for accurate interpretation.)

Ordering Information

Storage & Handling

• Store at 2–8°C in a dry, contamination-free environment.
• Do not expose discs to moisture or excessive heat to maintain potency.
• Use aseptic techniques when handling discs to prevent contamination.
