Microbial Analysis

Tracking/Trending Microbes

In QC operations of the pharmaceutical, medical device, health/cosmetics, and food industries, strain "tracking" is often useful in determining the source of microbes found to be contaminating the product or the production environment. Criteria essential for efficiently tracking the origins of strains are speed, accuracy, precision, and cost effectiveness. The comparative analysis of microbial strains (both known and unknown) has a broad range of applications in research. The visual representations of the relatedness between strains produced by tracking/trending can also help in a variety of research settings.

Custom Phylogenetic Trees

A Phylogenetic Tree is generated based on the differences between the sequences of library entries and/or client samples.

Base pair differences between two organisms are weighted differently to determine a percent similarity. The distances in the branches of the tree are mathematically calculated based on these percents and adjusted accordingly.

A Custom Phylogenetic Tree can be generated using any past or current sample sequenced by Microcheck and any of the species available in our validated databases. This tool can be very helpful when trying to determine the level of mutation imposed on a specific sample when compared to the original strain. This can also be a valuable asset in trending the changes within a species or genus over time. Records obtained from the gene sequencing procedure are always available to assist in the ease of accessing past data.
