Oxoid Polymyxin B 300 Units Antimicrobial Susceptibility Discs

Oxoid™ Polymyxin B 300 Units Antimicrobial Susceptibility Discs

Product Overview

Oxoid™ Polymyxin B 300 Units 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 Polymyxin B, a polypeptide antibiotic primarily active against Gram-negative bacteria.

Polymyxin B acts by disrupting the bacterial cell membrane, leading to rapid bacterial cell death. It is particularly effective against pathogens such as Pseudomonas aeruginosa, Acinetobacter species, and other multidrug-resistant Gram-negative organisms. Oxoid Polymyxin B discs help laboratories classify bacterial isolates as susceptible, intermediate, or resistant, supporting appropriate antimicrobial treatment decisions.

Key Features

• Standardized Antibiotic Potency: Each disc contains 300 units of Polymyxin B for reliable and reproducible testing.

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

• Convenient Cartridge System: Supplied in spring-loaded cartridges for easy and controlled dispensing.

• Moisture-Protected Packaging: Sealed cartridges with desiccant maintain disc stability and antibiotic potency.

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

Applications

Oxoid Polymyxin B 300 Units discs are widely used for in vitro antimicrobial susceptibility testing in:

• Clinical microbiology laboratories

• Hospital diagnostic laboratories

• Pharmaceutical laboratories

• Research and academic institutions

• Public health laboratories

The disc diffusion method measures the zone of inhibition, allowing microbiologists to determine bacterial sensitivity to Polymyxin B.
