Staphylococcus aureus Testing
Staphylococcus aureus is a Gram-positive bacterium commonly associated with human skin and respiratory contamination. It is a critical indicator of poor hygiene in manufacturing environments and must be absent in regulated products.
Tests We Offer
Pharmaceutical Products (USP <62>)
Staphylococcus aureus — Specified Microorganism (USP <62>)
Staphylococcus aureus is a Gram-positive organism commonly associated with human contamination and must be absent in regulated pharmaceutical products.
Test Methodology (USP <62>)
- Pre-enrichment in non-selective media
- Selective enrichment to suppress background flora
- Plating on selective/differential agar (e.g.,
Baird-Parker-type media)
- Confirmatory biochemical identification (coagulase and enzymatic testing)
This ensures accurate detection of low-level contamination from personnel or environment.
Dietary Supplements & Nutritional Products (USP <2022>)
Staphylococcus aureus — USP <2022> Absence Requirement
S. aureus must be absent in dietary supplements due to its association with toxin production and contamination from handling.
Test Methodology (USP <2022>)
- Sample preparation and homogenization
- Non-selective pre-enrichment phase
- Selective enrichment to enhance recovery
- Isolation on selective agar media
- Confirmatory identification using biochemical reactions
This method ensures reliable detection in high-organic-load products.
- Sample preparation and homogenization
Benefits
- Confirms personnel hygiene control
- Ensures GMP compliance
- Prevents contamination-related product failures
- Supports regulatory approvals
