QC Micro-organisms Receive Stamp of Approval from ATCC

Oxoid, is pleased to announce that the Remel Quality Control Micro-organisms (Culti-Loops® and Quanti-Cult®) available from Oxoid have recently been added to the ATCC (American Type Culture Collection) Licensed Derivative® Program*, which has been introduced for commercial organizations that use ATCC derived organisms within their products.

Inclusion in the program means that Culti-Loops and Quanti-Cult products containing ATCC-derived micro-organisms will bear the ATCC Licensed Derivative Emblem®, thus assuring customers that the viability, purity and identification of the micro-organisms have been tested and confirmed by the ATCC and maintaining the quality of the Oxoid and Remel Quality Control organism range. Such assurance is of enormous benefit to the global diagnostic and analytical testing market, supporting standards and increasingly stringent criteria for Quality Control (QC) testing within the industry.

Culti-Loops are stabilised micro-organisms, supplied ready to use in disposable bacteriological loops. Each loop is individually foil wrapped and, once removed, can be used to streak up to five agar plates.

Quanti-Cult and Quanti-Cult Plus® are preserved micro-organisms designed to deliver a specific range of colony forming units (CFU). Supplied in plastic vials, once rehydrated, they are ready to use immediately, eliminating the need for a growth period or serial dilutions. Quanti-Cult vials contain a single inoculum of less than 100 CFU in 0.3ml, whereas Quanti-Cult Plus vials deliver less than 100 CFU in 0.1ml, with each vial containing 10 inocula.

Culti-Loops and Quanti-Cult products are ideal for use in clinical, food, pharmaceutical, research and industrial applications for QC procedures, including: performance testing and method validation; microbial limit testing; bioburden testing; bacteriostasis and fungistasis testing; and growth promotion testing. They can also be used in the maintenance of stock cultures.

Julie Elston, QC organisms product manager at Oxoid, comments, “Standards and quality are important considerations for QC and the addition of the Culti-Loops and Quanti-Cult products to the ATCC Licensed Derivative Program further strengthens the benefits that these market leading brands offer to microbiologists around the world.”
