At Accugenix, we help you track and trend your microbial environment with expertise in Strain Typing and Microbial Characterization. Utilizing powerful, cGMP compliant tools for strain typing is essential when the questions are…
What is the source of contamination?
Is this production strain the correct one?
What are the normal flora of our production facility?
As a complement to our sequence-based microbial identification services, Accugenix offers AccuGENX-ST™ - strain typing by single or multi locus sequence typing (SLST or MLST), highly accurate sequence-based strain typing methods. We perform DNA sequencing of targets outside of the standard regions sequenced for microbial identification (16S, D2 or ITS2) to provide you with data to resolve differences and/or similarities at the strain level. Determination to the strain level allows you to definitively track the source of contamination or simply to verify your known strains. Not only is there a high level of microbial differentiation available by this method, the MLST and SLST raw sequence data are electronically retained in compliance with cGMP guidelines and accessible for comparison among your facilities for accurate trending and tracking.
RiboPrinter® – BacRib
Perfect companion tests to rDNA sequence-based identifications
Additionally, Accugenix offers automated ribotyping utilizing the DuPont Qualicon RiboPrinter® for strain-level characterization of bacterial isolates (BacRib). This fragment-based technology utilizes restriction enzymes (typically EcoRI and PvuII) to target and cut regions of the ribosomal RNA genes, resulting in a unique fingerprint of the bacterium. Automated ribotyping is useful for the comparison of restriction fragment patterns within the same species. These patterns can be generated prior to or subsequent to each other and be used to determine the level of similarity between isolates as part of a tracking and trending program.
