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. Staphylococcus aureus is a Gram-positive organism commonly associated with human contamination and must be absent in regulated pharmaceutical products. 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. Staphylococcus aureus — USP <2022> Absence Requirement 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.
