Of the 145 genera identified by 16S sequencing in the 51 samples in this study, the 27 most frequently identified genera are included in the table. Nine (9) of these 27 genera are obligate anaerobes, and culture did not attempt to detect these organisms. All 14 of the bacterial genera identified by culture are included in the table. The two bacteria detected by culture and not listed in the “16S DNA Sequencing” column of the table are Proteus and Aeromonas, which were detected using 16S sequencing 6 and 1 times, respectively. The frequency of identification of each genus is noted under the “Samples” heading.

* Genus present in both columns.
