Decreasing the time from gut microbiota analysis to publication

An increasing number of researchers have discovered the efficiency and simplicity of performing gut microbiota analysis using the GA-map® Dysbiosis Test.

The technology uses single nucleotide differences in the 16S rRNA gene to measure the abundance of species and groups of bacteria in a fecal sample. All pre-processing of the data is done by the GA-map® Analyzer software, hence no bioinformatician resources needed. Reports for microbiota profiles are automatically generated containing information on the dysbiosis index a measure of bacteria profile changes calculated based on the deviation from a reference population.

Merging the rapidness, preciseness and robustness of RT-PCR approach with the comprehensiveness of next-generation sequencing, the GA-map® technology drastically reduces the time from analysis to publication. Below, a selection of publications performed by using the GA-map® Dysbiosis Test is presented.

Number of publications: 21
