The advisory notifications highlight non-sterile aqueous pharmaceutical finished products as being a major culprit associated with many of these human infection events. As such, there has been a significant number of Bcc contaminated finished product recalls resulting in company revenue losses, delayed finished product release, finished product shortages for patients, manufacturing plant shutdowns coupled with company reputational damage. With many of the finished product recall events, pharmaceutical grade water and / or manufacturing facility water distribution systems have been identified as the primary origin source of Bcc contamination. Testing and monitoring regimes currently employed to identify Bcc contamination of water associated with pharmaceutical manufacturing are often limited by costly, laborious, lengthy and nonspecific traditional microbial culture-based methodologies. Presently FDA approved, European Conformity (CE) marked and International Organization for Standardization (ISO) standard microbial culture-independent rapid, quantitative, specific and sensitive Nucleic Acid Diagnostics (NAD) methodologies are now gaining greater widespread acceptance in their routine usage in testing laboratories. Here we present the development of a rapid (<4 hours from sample in to result out) single test culture-independent Bcc NAD method, incorporating a quantitative real-time Polymerase Chain Reaction (qPCR) assay. This method can be used for the detection and simultaneous identification of all 24 Bcc species currently assigned, directly from water samples. This culture-independent Bcc NAD method is validated to the testing method equivalent of the ISO/TS 12869:2019 standard, which is a widely used rapid culture-independent NAD method for detecting Gram-negative Legionella species in water. %U https://journal.pda.org/content/pdajpst/early/2023/02/23/pdajpst.2021.012728.full.pdf
