Species Information
The Helicobacter pylori J99 genome is 1.64 Million bp long and contains approximately 1535
predicted genes.
Taxonomy: Bacteria; Proteobacteria; Epsilonproteobacteria; Campylobacterales; Helicobacteraceae; Helicobacter.
Sequencing: The sequence was released 01/29/1999 by the ASTRA, and was described in Nature 397:176-80 (1999) Alm RA, Ling LS, Moir DT, King BL, Brown ED, et al.."Genomic-sequence comparison of two unrelated isolates of the human gastric pathogen Helicobacter pylori." Abstract: Helicobacter pylori, one of the most common bacterial pathogens of humans, colonizes the gastric mucosa, where it appears to persist throughout the host's life unless the patient is treated. Colonization induces chronic gastric inflammation which can progress to a variety of diseases, ranging in severity from superficial gastritis and peptic ulcer to gastric cancer and mucosal-associated lymphoma. Strain-specific genetic diversity has been proposed to be involved in the organism's... [Click above reference link for full abstract]

Sample position queries
A genome position can be specified by chromosomal coordinate range, COG
ID, or keywords from the GenBank or TIGR description of a gene.
The available chromosome/plasmid names are:
| Browser Chrom/Plasmid Name | Length (bp) | GC Content (%) | Gene Count | NCBI RefSeq Accession |
|---|
| chr | 1643831 | 39.19 | 1535 | NC_000921 |
The following list shows examples of valid position queries for this
genome:
| Request: | Genome Browser Response: |
|---|
| chr | Displays the entire sequence "chr" in the browser window |
| chr:1-10000 | Displays first ten thousand bases of the sequence "chr" |
| transporter | Lists all genes with "transporter" in the name or description |
| jhp0010 | Display genome at position of gene jhp0010 |

The Archaeal Genome Browsers at UCSC were developed by members of the
Lowe Lab (Kevin Schneider,
Katherine Pollard, Andy Pohl, Todd Lowe) and Robert Baertsch, with significant support from
the UCSC Human Genome
Browser group.
The Archaeal Browsers are run by a slightly modified
version of the UCSC Human Genome
Browser system. All queries, bug reports, content corrections, suggested improvements,
and new track data submissions should be sent to Todd Lowe (lowe
