In addition to routine testing, rtech also performs specialized Microbiological services. Services include shelf life studies, challenge studies (including USP and CTFA), microbial identification, and microbial quality investigation
rtech labs utilizes the latest technologies in bacterial identification and characterization. Identification of an unknown microbial isolate can be achieved through biochemical characterization and/or genetic characterization methodology offered by our laboratory.
The VITEK2® automated biochemical characterization system offers isolate identification to species for most organisms. Identification is obtained based on a series of biochemical reactions that create a biochemical pattern. For uncommon bacteria, our experienced technical staff can use this pattern, along with morphological information from selective agars, ancillary tests and direct microscopic observation to narrow the field to a select few possibilities.
For genetic characterization and tracking of strains, rtech labs utilizes the RiboPrinter® microbial characterization system. Using DNA fingerprint analysis, the RiboPrinter can identify environmental isolates, spoilage microorganisms, and pathogenic isolates. The bacterial isolate's genetic pattern is compared to a database containing over 6900 RiboPrint™ patterns, representing over 220 bacterial genera and over 1440 species and serotypes.
