Threshold TCC data are based on the maximum number of sequences observed in a negative or positive control for a particular OTU in each run.
Threshold TFA data are based on the false-assignment rate (0.02%) weighted by the total number of sequences of each OTU in each run.
Mycoplasma mycoides and Borrelia burgdorferi bacterial isolates were added as positive controls for PCR and indexing (i.e., PCalien) (see Fig. 1).
Data are given for the two MiSeq runs separately. NCPCR, negative controls for PCR; NCext, negative controls for extraction; NCmus, negative controls for dissection; PCBartonella_t, positive controls for PCR; PCBorrelia_b and PCMycoplsma_m, positive controls for PCR and positive controls for indexing; TCC and TFA, thresholds for positivity for a particular bacterium according to bacterial OTU and MiSeq run (see also Fig. 1).
