Fig. 2

The Enterobacteriaceae species prediction accuracy using 16S, gyrB, and dnaJ as the marker genes, tested on several SRA read data. For each species, the percent accuracy is shown as three grey bars ranging from 0 to 100 % (left vertical axis). The grey line represents the number of read data tested for each Enterobacteriaceae species (right vertical axis). The results shown in the TOTAL x-axis tick refer to the accuracy of all tested SRA read data; these data suggest that the gyrB marker genes gives a better accuracy than the 16S rRNA and the dnaJ marker genes
