RT Journal Article SR Electronic T1 Do Plant Isolates Have a Role in Method Suitability and Growth Promotion Testing in the Microbiology Laboratory? Is It a Matter of Science versus Compliance? JF PDA Journal of Pharmaceutical Science and Technology JO PDA J Pharm Sci Technol FD Parenteral Drug Association (PDA) SP 444 OP 460 DO 10.5731/pdajpst.2021.012675 VO 76 IS 5 A1 Dennis E. Guilfoyle A1 Anthony M. Cundell YR 2022 UL http://journal.pda.org/content/76/5/444.abstract AB In response to regulatory citations for not including plant isolates in method suitability and growth promotion testing of microbiological culture media, the authors make the case that the compendial designated cultures meet the requirements of the official tests and are sufficiently representative of the most frequently identified environmental isolates. It was our conclusion that this compliance request lacks scientific justification. The scope of this review was largely directed to the growth promotion and suitability testing requirements for USP <60>, <61>, <62>, and <71>. Other microbiological tests such as USP <51> Antimicrobial Effective Testing, media fill validation, and water and environmental monitoring are discussed.
