a
Range of 6 to 14 genes, with the majority having 8 to 11 genes. The median value is shown.
b
Range of 4 to 15 genes, with the majority having 6 to 11 genes. The value shown is for the predominant species.
c
Range of 5 to 8 genes. The median value is shown.
d
Range of 2 to 15 genes, with the majority having 6 to 15 genes. The value shown is for the predominant species.
e
Identifications of bacterial species/groups were based on the target sequences listed. The copy number of ribosomal genes for each bacterial species/group was determined on the basis of data from the NCBI database.
