Genomics of Helicobacter Species 91
Genomics of Helicobacter Species 91 6 Genomics of Helicobacter Species Zhongming Ge and David B. Schauer Summary Helicobacter pylori was the first bacterial species to have the genome of two independent strains completely sequenced. Infection with this pathogen, which may be the most frequent bacterial infec- tion of humanity, causes peptic ulcer disease and gastric cancer. Other Helicobacter species are emerging as causes of infection, inflammation, and cancer in the intestine, liver, and biliary tract, although the true prevalence of these enterohepatic Helicobacter species in humans is not yet known. The murine pathogen Helicobacter hepaticus was the first enterohepatic Helicobacter species to have its genome completely sequenced. Here, we consider functional genomics of the genus Helico- bacter, the comparative genomics of the genus Helicobacter, and the related genera Campylobacter and Wolinella. Key Words: Cytotoxin-associated gene; H-Proteobacteria; gastric cancer; genomic evolution; genomic island; hepatobiliary; peptic ulcer disease; type IV secretion system. 1. Introduction The genus Helicobacter belongs to the family Helicobacteriaceae, order Campylo- bacterales, and class H-Proteobacteria, which is also known as the H subdivision of the phylum Proteobacteria. The H-Proteobacteria comprise of a relatively small and recently recognized line of descent within this extremely large and phenotypically diverse phy- lum. Other genera that colonize and/or infect humans and animals include Campylobac- ter, Arcobacter, and Wolinella. These organisms are all microaerophilic, chemoorgano- trophic, nonsaccharolytic, spiral shaped or curved, and motile with a corkscrew-like motion by means of polar flagella. Increasingly, free living H-Proteobacteria are being recognized in a wide range of environmental niches, including seawater, marine sedi- ments, deep-sea hydrothermal vents, and even as symbionts of shrimp and tubeworms in these environments. -

Page 1/18 Abstract Background: Helicobacter himalayensis was isolated from Marmota himalayana in the Qinghai-Tibet Plateau, China, and is a new non-H. pylori species, with unclear taxonomy, phylogeny, and pathogenicity. Results: A comparative genomic analysis was performed between the H. himalayensis type strain 80(YS1)T and other the genomes of Helicobacter species present in the National Center for Biotechnology Information (NCBI) database to explore the molecular evolution and potential pathogenicity of H. himalayensis. H. himalayensis 80(YS1)T formed a clade with H. cinaedi and H. hepaticus that was phylogenetically distant from H. pylori. The H. himalayensis genome showed extensive collinearity with H. hepaticus and H. cinaedi. However, it also revealed a low degree of genome collinearity with H. -

HELICOBACTER: CHRONIC EFFECTS AND ROLE IN HOST MICROECOLOGY TORKEL WADSTRÖM and ÅSA LJUNGH Department of Medical Microbiology, Dermatology and Infection, Lund University, Lund, Sweden SUMMARY Helicobacter pylori is the first named species of the Helicobac- ter/Wolinella family, now including more than 20 species and about 10 candidate species. The organisms are all micro-aerophilic “mucino- philes” with a few exceptions. H. pylori is the prototype for a number of bile-sensitive species colonising the stomach of most mammals, in- cluding dolphins and whales. The low toxicity of the lipopolysaccharide (LPS) and a number of properties unique for these species determine how they may cause life-long infections. H. pylori carries the vacA toxin as well as a set of other virulence traits permitting optimal early coloni- sation of the host, e.g. in childhood. The cagA pathogenicity island (PAI) makes cagA+ strains of H. pylori more virulent than cagA- strains to develop chronic active gastritis, gastric atrophy and pre-cancerous le- sions in the host as well as in mouse and mongolian gerbil models. H. pylori as well as a number of entero-hepatic bile-tolerant species are camouflaged from the innate immune system of the GI epithelial cell surfaces, yet cagA+ H. pylori transcribe NF-κB to the nucleus of these cells and of macrophages and other cells. At least H. pylori evades the host immune system by a number of responses such as molecular mimicry of the H–K adenosine triphosphatase and of gastric cell surface fucosylated antigens. -

Abstract Background: Hepato-biliary tract lithiasis is common and present either as pain or as asymptomatic on abdominal ultrasonography for other causes. Although the DNA of Helicobacter species are identified in the gallbladder bile, tissue or stones analyzed from these cases, still a causal relationship could not be established due to different results from different geographical parts. Methods: A detailed search of pubmed and pubmedcentral was carried out with key words Helicobacter and gallbladder, gallstones, hepaticolithiasis, cholelithiasis and choledocholithiasis, benign biliary diseases, liver diseases. The data was entered in a data base and meta analysis was carried out. The analysis was carried out using odds ratio and a fixed effect model, 95% confidence intervals for odds ratio was calculated. Chi square test for heterogeneity was employed. -
