10.1038/nature08821, Rawls JF, Mahowald MA, Ley RE, Gordon JI: Reciprocal gut microbiota transplants from zebrafish and mice to germ-free recipients reveal host habitat selection. The microbiota of the GI tract plays an important role in the digestion and chemical processing of the food as exemplified by the large number of bacteria involved in vitamin production and fermentation of saccharides and beta-glycans (cellulose, hemicellulose) (Table 2). 2009) suggests a more important role. 10.1128/MMBR.68.3.403-431.2004. Department of Biology, McGill University, 1205 Docteur Penfield, Montreal, Quebec, ... we assess the sensitivity of 454 pyrosequencing for detection of rare species using known indicator species spiked into existing complex plankton samples. In a recent study, in which the close association of Planctomycetes with the brown seeweed kelp (Laminaria hyperborea) was investigated, it was hypothesized that these bacteria are degraders of sulfated polysacharides produced by kelp (Bengtsson and Ovreas 2010). With this technology, as many as 20 million base pairs of genome sequence can be learned in an instrument run of less than 6 hours. 13.15). Pyrosequencing of 16S rRNA gene amplicons to study the microbiota in the gastrointestinal tract of carp (Cyprinus carpio L.). Water quality of the system was maintained by a biofilter and a weekly water replacement of 10% of the total volume. 2011; Roeselers et al. The morphology of the GI tract of fishes varies greatly among species. A total of 14,034 variations were identified by 454 pyrosequencing versus 3,632 variations by Sanger clone-based (SCB) sequencing. A Megablast search (using default parameters) of all sequenced reads larger than 100 nt against the Silva SSURef database (version 102) was done to extract all 17,892 16S rRNA gene sequences (average length 314 nt). By using this website, you agree to our Pyrosequencing is a DNA sequencing technology based on the sequencing-by-synthesis principle. PubMed Microbiol Mol Biol Rev 2004, 68: 403–431. What is Sanger Sequencing? Ten fish (male and female) weighing 60 to 158 gram were used. In this method, a DNA fragment to be sequenced is radiolabeled at one end of molecule (Fig. Appl Environ Microbiol 1995, 61: 4128–4130. Aquaculture 2010, 303: 1–7. Verrucomicrobiae species are most commonly found in aquatic environments but are also known members of the gut microbiota in different organisms including seacucumbers (Echinodermata), termites and humans (Wagner and Horn 2006). 77 sequences were classified as cyanobacteria-like, probably these are chloroplast sequences that originate from the plant components of the food (Additional file 2).

Furthermore, the presence of high number Proteobacteria has also been shown for zebrafish, which is closely related to carp (Rawls et al. Microb Ecol 2009, 57: 550–561. Then the order in which the nucleotides have to be added in the sequencer is chosen (i.e. We investigated the diversity of the microbiota in common carp (Cyprinus carpio), one of the most cultivated freshwater fish species worldwide (FAO, 2011). Other bacteria isolated were Enterobacteriaceae (Sugita et al. Saha AK, Ray AK: Cellulase activity in rohu fingerlings. Enterobacterium spp. 2004). Aquaculture 1991, 92: 267–276. It should be noted that the use of multiple primer sets biases the number of sequences belonging to the identified taxa. PubMed Google Scholar.

Pyrosequencing® is a unique system that allows the analysis of genetic variations including single-nucleotide polymorphisms, indels and short repeats, as well as assessing RNA allelic imbalance, DNA methylation status, and gene copy number. A problem with 454 pyrosequencing is 'blinding' of the camera due to flashing caused by incorporation of the same nucleotide in many spots, which can occur when many similar DNA templates are sequenced (Kip et al. Furthermore, a separate lineage within the Planctomycetes, the anammox bacteria, were present in the carp gut (Figure 1). Int J Syst Evol Microbiol 2002, 52: 173–178. ISME J 2011, 1–14. PubMed In any well where the complementary nucleotide is present at the 3' end of the template, the nucleotide is added and pyrophosphate is liberated.

In this study, Roche 454 pyrosequencing was applied to a pooled set of different 16S rRNA gene amplicons obtained from GI content of common carp (Cyprinus carpio) to make an inventory of the diversity of the microbiota in the GI tract. 10.1038/nrg2319. Another abundant phylum within our amplicon sequences were the Verrucomicrobiae (including subdivision 3 and 4 (Optitiae)). Another well represented group within the obtained sequences were the Bacteroidetes (22% of obtained sequences), a phylum known for a fermentative metabolism and degradation of oligosaccharides derived from plant material (Van der Meulen et al. In laboratories around the world there is an intense desire to sequence more genomes. 2006) and could also play a role in the metabolism of plant beta glycans in carp GI tract. Int J Syst Evol Microbiol 2007, 57: 2680–2687. The GI microbiota is important for the health of the animal and therefore this study could be relevant for aquaculture.

Obtained amplicons from all different reactions were mixed and sequenced using Roche 454 titanium technology and this revealed a high microbial diversity in the GI tract of common carp (Cyprinus carpio). Common carp (Cyprinus carpio L.) were kept in 140 L tanks in a closed recirculating aquaculture system with a total volume of 3000 L at the Radboud University Nijmegen (The Netherlands). Pyrosequencing was employed to produce sequence data for 30 nucleotides. 10.1078/072320203322346010, PubMed 1990; Namba et al. The confidence threshold used was 50%.

Figure 1 displays the taxonomic classification derived from mapping the pyrosequencing reads to the Silva SSURef database, which classified 17,641 reads (99%). Furthermore, a few sequences (< 1%) were identified as Opitutae, Chlamydiae. Moya et al. Pimental-Elardo S, Wehrl M, Friedrich AB, Jensen PR, Hentschel U: Isolation from Planctomycetes from Aplysina sponges. G-A-T-C). Several new methods are being developed and one is already commercially available (the Genome Sequencer 20 System). 2010) which decreases after antibiotic treatments (Saha and Ray 1998), indicating that the GI microbiota is responsible for this activity. But now a great effort is being expended to find ways to sequence DNA more rapidly (and more cheaply). There are different DNA sequencing methods. After a primer is annealed to the end of the ssDNA, synthesis is ready to begin. Bas E.

Furthermore, obtained sequences were processed using the Classifier tool (Wang et al. BMC Biology 2009, 7. By using labelled glucose, it has been shown that these bacteria are involved in saccharide fermentation (Li et al. Pyrosequencing is a method of DNA sequencing that differs from Sanger sequencing, in that it relies on the detection of pyrophosphate release and the generation of light on nucleotide incorporation, rather than chain termination with dideoxynucleotides. 1990), Bacillus (Sugita et al. Pyrosequencing. Aquac Int 1998, 6: 281–291. Similar results were obtained when the RDP database pyrosequencing pipeline was used, which classified 16,768 reads (94%, Additional file 1). Pyrosequencing is a real-time and non-electrophoretic technique, which dispenses with the need for labeled nucleotides and labeled primers. CAS A similar search using BLAST revealed 16 different genes. The presence of nitrogen cycling bacteria in fishes could offer new in situ solutions for the removal of nitrogen from aquaculture systems. The use of culture-independent studies such as molecular screening of the 16S rRNA gene may be a more reliable method to estimate microbial diversity in the GI tract of fish (Wu et al. PubMed Central Sugita H, Miyajima C, Deguchi Y: The vitamin B12 producing ability of the intestinal microflora of fresh-water fish. Pyrosequencing delivers sequence information, various types of genetic variation can be evaluated — insertion-deletions, SNPs, short tandem repeats, and variable gene copy number — and it is possible to assay several contiguous sequence variants in a single run.
