*GPR, gram-positive rods; GNR, gram-negative rods; GPC, gram-positive cocci.
†initial and reviewed clusters sizes indicate number of isolates in each cluster before and after manual review, outcome of manual review, and most similar valid species names are listed. Manual review was performed for all clusters with at least 5 isolates. Sequences were aligned with type strain sequences, and manual BLAST (23) analysis was performed to calculate pairwise sequence identities.
