Eurofins offers multiple technologies and approaches to Identification (ID) Testing to provide the appropriate level of identification to fit your needs. From identification of environmental isolates through expert analysis of finished product contaminants, we offer the most comprehensive ID services available for bacteria, molds and yeasts.

We also offer typing services to trace the source and investigate the root cause of contamination by establishing the unique fingerprint of microorganisms.

Why Choose Eurofins?

  • We have more than 15 years of experience providing  comprehensive microbial identification support to the pharmaceutical industries.
  • We have vast experience with all species of  bacteria and fungi found in the pharma industry.
  • We have the largest libraries of reference  sequences worldwide for bacteria and fungi.
  • Our standard turnaround time is 3-5 business  days with priority services upon request.

Genotypic Identification

Regular Service
Unilocus Comparative Sequencing (ULSA)

Bacteria: 16S rRNA Gene Long Sequencing
Uses PCR to amplify more than 1,350 base pairs, double strand sequencing and comparison to our validated, proprietary database, Eurofins Microbial Sequencing Index (EMSI), including more than 8,450 valid type strains.

  • Genus and species level identification
  • More accurate than partial sequencing
  • Rapid, reliable and efficient

Fungi : 25S rRNA Gene or ITS1/ITS2 Partial Sequencing
Uses 25S rRNA gene.

  • Genus and species level identification
  • Rapid, reliable and efficient

Expert Service
Multilocus Comparative Sequencing (MLSA)
Solves drawbacks from 16S rRNA (bacteria) or 25S rRNA genes, ITS1 and/or ITS2 (fungi), sequencing by increasing resolution to further discriminate at the species level.

  • Simultaneous comparative sequencing of multiple genes (HouseKeeping Genes: HKG) of taxonomical interest and extended databases of reference sequences: bacteria and molds
  • Application to strain typing (MLST)

Molecular Typing

Bacteria and Fungi Molecular ID Cards
Generates fingerprints of isolates in order to determine if they correspond to different strains of the same species for critical investigations, such as media fill test and sterility test failures. Typing methodologies available, including:

  • MultiLocus Sequence Typing (MLST)
  • Arbitrary Primed PCR (APPCR)
  • Variable Number of Tandem Repeats (VNTR)
  • Pulse Field Gel Electrophoresis (CHEF)
  • MicroSatellite Analysis (MSAT)
