a
The numbers of bacterial or fungal species identified are listed. “Corroborated” indicates species not identified by culture but detected by another analytical tool. “Uncorroborated” indicates that no other analytical tool identified the species.
b
Data represent numbers of additional species that represented the top organism detected but that failed to meet the threshold for identification as presented.
