Marker Frequency Analysis of Vibrio cholerae E7946 mutants (YAV20, AB14 and AB23)
YAV20 (E7946 loxP[dciA] SpR lacZ::cre ZeoR), AB14 (YAV20 inv[glmU-mioC]) and AB23 ( YAV20 ?recB::CmR) were created by natural transfromation using cognate plasmids. Cells were grown in the M( minimla media supplemented with fructose, with  or without arabinose (ara).  Genomic DNA was extracted with the Sigma GenElute® bacterial genomic DNA kit to generate a genomic library according to Illumina's protocol. The libraries and the sequencing were performed by the High-throughput Sequencing facility of the I2BC (https://www.i2bc.paris-saclay.fr/sequencing/ng-sequencing/, CNRS, Gif-sur-Yvette, France). Genomic DNA libraries were made with the 'Nextera DNA library preparation kit' (Illumina) following the manufacturer's recommendations.
