Table 2.

Operational taxonomic units (OTUs) with a step-wise change in relative abundance that follows changes in renal function.

OTUs with increased relative abundance

Acinetobacter Spp.*

Allobacukum Spp.*

Campylobacter s_

Lactobacillaceae g_ s_*

Plancoccaceae g_ s_*

Pyramidobacter Piscolens

Pyramidobacter Spp.

Sphingobium s_

Streptococcus Spp.*

Limnohabitans Spp.

OTUs with decreased relative abundance

Bilophila Spp.*

Oscillospira Spp.*

A significantly different changes in relative abundance was noted in multiple OTUs, mostly increased in relative abundance with worsening renal failure. Only Bilophila and Oscillospira genera showed a nominal decrease in relative abundance with worsening renal function.

*Significant change in a non-cultured species along with the changes noted on the genera level.

**Changes seen in a non-cultured species from the corresponding family.
