 As a result, any taxonomic signature from these plasmids
 is both specific enough to the target taxon and general enough to help avoid any misidentifications.
 
+Finally, it is important to mention that the chromosomes of three significant pathogens are not included in the list of chromosomes, but their plasmids are listed:

+If these chromosomes were present in a metagenomics analysis,
+then any matches against, e.g., _B. cereus_, would match against multiple species thereby giving less helpful genus-level results, e.g., _Bacillus_.

 Kalamari uses the NCBI Taxonomy database as a baseline.
