Results and Pritelivir datasheet discussion 454 pyrosequencing and identification of endosymbionts in Otiorhynchus spp A total of ~48,000 PCR amplicons were sequenced via GS FLX titanium 454 sequencing, of which ~27,000 reads were assembled after having passed the additional quality controls. These sequences were summarized into 49 consensus sequences (Table 1), representing the total retrieved endosymbiotic bacterial diversity in the four different Otiorhynchus species. Sequence abundances of the respective OTUs were different in each weevil species analysed.
We expect these differences in sequence abundance within the 16S rDNA amplicons to reflect the respective bacterial abundances in the sample.
