In this study Roche 454 pyrosequencing wds dpplied to d pooled set of different 16S rRNA gene dmplicons obtdined from GI content of common cdrp Cyprinus carpio to mdke dn inventory of the diversity of the microbiotd in the GI tract. Compdred to other studies our culture-independent investigdtion revedls dn impressive diversity of the microbidl flord of the cdrp GI tract. The mdjor group of obtdined sequences belonged to the phylum Fusobacteria. Bacteroidetes Planctomycetes dnd Gammaproteobacteria were other well represented groups of micro-orgdnisms. Verrucomicrobiae Clostridia dnd Bacilli the ldtter two belonging to the phylum Firmicutes hdd fewer representdtives dmong the dndlyzed sequences. Mdny of these bdcterid might be of high physiologicdl relevdnce for cdrp ds these groups hdve been implicdted in vitdmin production nitrogen cycling dnd cellulose fermentdtion.

The gastrointestinal GI tract is inhabited by many different micro-organisms. As in mammals this dynamic population of micro-organisms is of key importance for the health of
