Charles River is committed to providing the most accurate identifications to the industries we serve. This commitment requires that we continuously update our validated Accugenix® libraries to stay current with an evolving microbial world, where taxonomic changes and new species are described daily.

To ensure we continually provide the best identification services available, we routinely evaluate our identification rate for customers' bacterial and fungal samples. Since our objective is to achieve the highest percentage of species-level identifications, we compare sample sequence data that do not result in a species-level match against a variety of publicly available sequence databases. If a newly described organism is a good match for those sample sequences and is validly named and published, the sequence proceeds to our validated library entry process, where it undergoes extensive testing and review prior to approval and entry into the Accugenix® library.
