Oxoid 0129 – 10 μ Discs

Oxoid 0129 – 10 μg Discs – Diagnostic Test for Vibrio Differentiation

Oxoid 0129 – 10 μg discs are specialized diagnostic test discs used in clinical and research microbiology laboratories to help differentiate Vibrio species from other Gram‑negative rods. These discs contain the vibrio static agent 0129 (2,4‑Diamino‑6,7‑di‑iso‑propylpteridine phosphate) at a 10 μg concentration per disc to exploit the unique sensitivity pattern of Vibrio bacteria.

What Are Oxoid 0129 – 10 μg Discs?

Oxoid 0129 discs are ready‑to‑use filter‑paper discs impregnated with the 0129 reagent. They are designed for agar diffusion testing in microbiology to observe growth inhibition patterns that help distinguish Vibrio species from other similar Gram‑negative organisms like aeromonads.

How They Work

When placed on an agar plate inoculated with a clinical isolate:

• The 0129 reagent diffuses outward from the disc.
• Organisms with sensitivity to 0129 show an inhibition zone around the disc.
• Vibrio isolates often show characteristic susceptibility or resistance patterns that aid identification.
  For example, several Vibrio species may be resistant at 10 μg but sensitive at higher concentrations, which helps differentiate them from unrelated Gram‑negative rods.

Key Features

• Diagnostic use: Helps differentiate Vibrio species from other Gram‑negative bacteria.
• Controlled concentration: Standardized 10 μg per disc for consistent testing.
• Easy to use: Ready‑to‑use discs for agar plate testing.
• Rapid results: Detects inhibitory effects in standard incubation periods.

Applications

• Clinical microbiology laboratories for bacterial differentiation.
• Food testing and water microbiology to screen for Vibrio contamination.
• Research labs studying Gram‑negative bacterial identification.

Important Note

Oxoid 0129 – 10 μg discs are for in vitro laboratory use only. These discs are not medicines and should never be used for treating infections. Always follow proper laboratory safety protocols when handling cultures and testing reagents.
