Distribution of culture independent TEF1-α clones from PSU colony- and NYC-derived larvae into Operational Taxonomic Units (OTUs). All 277 sequences clustered into two distinct OTUs. OTU1 was the most abundant OTU as it was detected in all NYC- and all PSU-derived samples. OTU2 was not detected in any of the NYC samples, but was detected in a subset of the PSU samples.
