Oxoid Nalidixic Acid 30 µg Antimicrobial Susceptibility Discs

Oxoid™ Nalidixic Acid 30 µg Antimicrobial Susceptibility Discs

Product Overview

Oxoid™ Nalidixic Acid 30 µg Antimicrobial Susceptibility Discs are designed for antimicrobial susceptibility testing (AST) in clinical, hospital, and research microbiology laboratories. These discs are used in the disc diffusion method to evaluate bacterial susceptibility to Nalidixic Acid, a first-generation quinolone antibiotic.

Nalidixic Acid is primarily effective against Gram-negative bacteria, particularly members of the Enterobacterales family, and is commonly used for urinary tract infections (UTIs). Oxoid Nalidixic Acid discs allow laboratories to classify bacterial isolates as susceptible, intermediate, or resistant, supporting accurate antimicrobial therapy decisions.

Key Features

• Standardized Antibiotic Potency: Each disc contains 30 µg of Nalidixic Acid for consistent and reproducible testing.

• Designed for Disc Diffusion AST: Suitable for routine antimicrobial susceptibility testing in microbiology laboratories.

• Convenient Cartridge Format: Supplied in spring-loaded cartridges for safe and controlled dispensing.

• Moisture-Protected Packaging: Individually sealed cartridges with desiccant maintain disc stability and potency.

• High-Quality Manufacturing: Produced by Thermo Fisher Scientific under strict quality standards.

Applications

Oxoid Nalidixic Acid 30 µg discs are used for in vitro antimicrobial susceptibility testing in:

• Clinical microbiology laboratories

• Hospital diagnostic laboratories

• Pharmaceutical and research laboratories

• Public health and epidemiology laboratories

The disc diffusion method allows microbiologists to measure zones of inhibition, helping detect bacterial sensitivity and identify resistant strains.
