Fig 4. Metagenomic analyses of virulence factors (VFs) at six locations along sewage flow in the STP.

Fig 4

Sequence number (A) and types (B) of virulence factors were calculated based on alignment of the Illumina shotgun sequences (normalized to 9,000,000 reads for each sample) against MvirDB protein database.
