Summary: At a glance summaries of studies on rapid sterility testing for ATMPs, pathogenic Avian flu testing, incidence of B. cereus in infant formula, accurate serotyping of S. pneumoniae.
Using an automated blood culture system, researchers demonstrated that mesenchymal stem cell (MSC) therapeutic preparations can be reliably screened for microbial contamination within 48 hr, supporting substantially faster product release compared with conventional 14-day sterility testing.
