Proportion of sequencing reads for different organisms across 4346 WGS samples from 20 different studies. Each dot represents a sample with a given percentage of sequencing reads coming from the genus indicated in the y-axis. Dashed lines highlight the target organism of each study. A 0.3 of vertical jitter was applied for better visualization. Only organisms in a proportion above 2% are shown. a Studies of the bacterial dataset. b Studies of the MTB dataset. The two Enterococcus species analyzed in the bacterial dataset are shown under the same rectangle as they belong to both the same genus and the same study
