OXOID Pseudomonas Cetrimide Agar

OXOID Pseudomonas Cetrimide Agar – Selective Medium for Pseudomonas aeruginosa

OXOID Pseudomonas Cetrimide Agar is a highly selective microbiological culture medium specifically designed for the isolation and identification of Pseudomonas aeruginosa. Produced by Oxoid Ltd, this medium is widely used in clinical, pharmaceutical, and environmental laboratories for reliable detection of this important pathogen.

Key Features of OXOID Cetrimide Agar

• Highly Selective Medium: Contains cetrimide to inhibit most bacteria except Pseudomonas aeruginosa
• Enhanced Pigment Production: Promotes production of pyocyanin and fluorescein
• Easy Identification: Characteristic colony color and fluorescence under UV light
• Consistent Quality: Manufactured under strict QC standards
• Convenient Format: Available as dehydrated powder for easy preparation

Composition of Cetrimide Agar

The formulation typically includes:

• Peptone
• Magnesium chloride
• Potassium sulfate
• Cetrimide (selective agent)
• Agar

These components support growth while enhancing pigment production of Pseudomonas species.

Principle of Cetrimide Agar

Cetrimide Agar works based on selective inhibition and pigment stimulation:

• Cetrimide suppresses unwanted microbial flora
• Pseudomonas aeruginosa grows and produces:
  • Pyocyanin (blue-green pigment)
  • Fluorescein (yellow-green fluorescence under UV light)

This makes identification quick and reliable.

Colony Characteristics

• Pseudomonas aeruginosa:
  • Blue-green colonies
  • Fluorescent pigment under UV light
• Other bacteria: Inhibited or minimal growth

Applications

• Clinical microbiology labs (wound, urine, respiratory samples)
• Pharmaceutical quality control
• Cosmetics and water testing
• Environmental monitoring
• Research and academic laboratories

Advantages

• Highly specific for Pseudomonas aeruginosa
• Supports rapid visual identification
• Reduces contamination risk
• Trusted performance from Oxoid Ltd

Storage and Handling

• Store at 10–30°C in a dry environment
• Keep tightly sealed to prevent moisture absorption
• Prepare according to manufacturer guidelines
