Eurofins | ams microbial identification via genetic analysis

Click2Contact

The genetic identification services Eurofins | ams provides allow for the identification and characterisation of bacterial, yeast and mould isolates to the species level. This genetic identification technology outperforms phenotypic approach (such as the MALDI-ToF) in terms of accuracy in identification, according to the company.

With 8470 valid bacteria type strains entries, the Eurofins IDmyk Comparative Sequence Index database, which is proprietary to Eurofins, is said to be the largest database in the world. The Eurofins IDmyk fungal database (1650 species) complements the bacterial library. As the company notes, the larger the database, the better the discrimination.

In Eurofins | ams, routine bacterial identification via genetic sequencing is performed (by default) using the long sequence (1200–1400 base pairs) of the rDNA. The longer sequence allows for better discrimination of closely related species and therefore gives higher confidence in the results provided.

For clients who need differentiation of bacteria at the strain level, molecular typing services are also available, as the company works closely with Eurofins IDmyk in Lyon, France.

Genetic identification is useful for helping to provide identification for unknown isolates that are found to be present in critical areas in an aseptic setting. This is vital for both investigation purposes and regulatory requirement.
