Oxoid Sulphamethoxazole/Trimethoprim 25 µg( Cotrimoxazole) Antimicrobial Susceptibility Discs

Oxoid™ Sulphamethoxazole/Trimethoprim 25 µg Antimicrobial Susceptibility Discs

Product Overview

Oxoid™ Sulphamethoxazole/Trimethoprim 25 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 the combination antibiotic Sulphamethoxazole and Trimethoprim.

This antimicrobial combination works by sequential inhibition of bacterial folic acid synthesis, providing enhanced antibacterial activity compared to either drug alone. It is widely effective against a range of Gram-positive and Gram-negative bacteria, making it useful in the treatment of urinary tract infections, respiratory infections, gastrointestinal infections, and certain opportunistic infections.

Using Oxoid Sulphamethoxazole/Trimethoprim discs, laboratories can determine whether bacterial isolates are susceptible, intermediate, or resistant, helping clinicians select appropriate antimicrobial therapy.

Key Features

• Combination Antibiotic Disc: Each disc contains Sulphamethoxazole and Trimethoprim with a total potency of 25 µg.

• Standardized AST Testing: Suitable for routine disc diffusion antimicrobial susceptibility testing.

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

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

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

Applications

Oxoid Sulphamethoxazole/Trimethoprim 25 µg discs are used for in vitro antimicrobial susceptibility testing in:

• Clinical microbiology laboratories

• Hospital diagnostic laboratories

• Pharmaceutical laboratories

• Academic and research institutions

• Public health laboratories

The disc diffusion method measures the zone of inhibition, allowing microbiologists to determine the effectiveness of the Sulphamethoxazole/Trimethoprim combination against bacterial isolates.
