Figure 4. The distribution of phylotypes by class from 16S rRNA clone libraries.

Libraries have been pooled by site (i.e. libraries from all fragments at a given time point from Far-1 and Far-2 are represented by “Far” and the same is true for “Near”) and each individual time point (T0, T-5 days, T-22 days) is shown separately. The number of sequences represented is denoted as “n = ”. Spirochaetes, previously seen only in corals infected with diseases, and Clostridia are both present even though fragments showed no visible signs of disease. Spirochaetes sequences are only present at T-5 days and predominantly at high effluent sites.
