Pseudomonas aeruginosa Testing

Pseudomonas aeruginosa is a waterborne Gram-negative bacterium known for its resistance to disinfectants and ability to survive in pharmaceutical water systems. It is a major concern in non-sterile manufacturing environments.

Tests We Offer

Pharmaceutical Products (USP <62>)

• Pseudomonas aeruginosa — Specified Microorganism (USP <62>)

  Pseudomonas aeruginosa is a waterborne Gram-negative organism that must be absent in non-sterile pharmaceutical products due to its resistance and opportunistic pathogenicity.

  Test Methodology (USP <62>)

  • Pre-enrichment in non-selective broth media
  • Selective enrichment promoting Pseudomonas growth
  • Isolation on selective agar (e.g., cetrimide-based media)
  • Confirmatory identification using biochemical profiling (oxidase reaction, pigment production, etc.)
  This method is optimized for detecting water-system contamination

Benefits

• Ensures water system integrity
• Detects environmental contamination
• Supports GMP compliance
• Reduces risk in topical and liquid products
