Wolinella
The genus ''Wolinella'' is a member of the Campylobacterales order of Bacteria. The order Campylobacterales includes human pathogens such as ''Helicobacter pylori'' and ''Campylobacter jejuni''. Strains The only publicly available strain of ''Wolinella'' is '' Wolinella succinogenes'' DSM 1740 (ATCC 29543). The original isolation of this organism was done by M. J. Wolin, E. A. Wolin and N. J. Jacobs at the University of Illinois. This original isolation was done from bovine rumen fluid and was somewhat serendipitous as the researchers were intending to isolate methanogenic organisms. This bacterium was originally classified as ''Vibrio succinogenes'', but was reclassified in 1981 to ''Wolinella succinogenes'' by A. C. R. Tanner ''et al''. Strains of ''Wolinella'' have been isolated from feline and canine oral cavities. Only one strain is currently published with ''Candidatus'' status: ''Candidatus Wolinella africanus''. This strain was isolated from the upper digestive tracts of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sulfurimonas
Sulfurimonas is a bacterial genus within the class of Campylobacterota, known for reducing nitrate, oxidizing both sulfur and hydrogen, and containing Group IV hydrogenases. This genus consists of four species: ''Sulfurimonas autorophica'', ''Sulfurimonas denitrificans'', ''Sulfurimonas gotlandica'', and ''Sulfurimonas paralvinellae''. The genus' name is derived from "''sulfur"'' in Latin and ''"monas"'' from Greek, together meaning a “sulfur-oxidizing rod”. The size of the bacteria varies between about 1.5-2.5 μm in length and 0.5-1.0 μm in width. Members of the genus ''Sulfurimonas'' are found in a variety of different environments which include deep sea-vents, marine sediments, and terrestrial habitats. Their ability to survive in extreme conditions is attributed to multiple copies of one enzyme. Phylogenetic analysis suggests that members of the genus ''Sulfurimonas'' have limited dispersal ability and its speciation was affected by geographical isolation rather than hydr ...

Sulfurovum
''Sulfurovum'' is a genus within the ''Campylobacterota Campylobacterota are a phylum of bacteria. All species of this phylum are Gram-negative. The Campylobacterota consist of few known genera, mainly the curved to spirilloid ''Wolinella'' spp., ''Helicobacter'' spp., and ''Campylobacter'' spp. Most ...'' which was first described in 2004 with the isolation and description of the type species ''Sulfurovum lithotrophicum'' from Okinawa trough hydrothermal sediments. Named for their ability to oxidize sulfur and their egg-like shape, cells are gram-negative, coccoid to short rods. Mesophilic chemolithoautotrophic growth occurs by oxidation of sulfur compounds coupled to the reduction of nitrate or molecular oxygen.

Helicobacter
''Helicobacter'' is a genus of Gram-negative bacteria possessing a characteristic helical shape. They were initially considered to be members of the genus '' Campylobacter'', but in 1989, Goodwin ''et al.'' published sufficient reasons to justify the new genus name ''Helicobacter''. The genus ''Helicobacter'' contains about 35 species. Some species have been found living in the lining of the upper gastrointestinal tract, as well as the liver of mammals and some birds. The most widely known species of the genus is ''H. pylori'', which infects up to 50% of the human population. It also serves as the type species of the genus. Some strains of this bacterium are pathogenic to humans, as they are strongly associated with peptic ulcers, chronic gastritis, duodenitis, and stomach cancer. ''Helicobacter'' species are able to thrive in the very acidic mammalian stomach by producing large quantities of the enzyme urease, which locally raises the pH from about 2 to a more biocompatib ...

Campylobacterota
Campylobacterota are a phylum of bacteria. All species of this phylum are Gram-negative. The Campylobacterota consist of few known genera, mainly the curved to spirilloid ''Wolinella'' spp., ''Helicobacter'' spp., and '' Campylobacter'' spp. Most of the known species inhabit the digestive tracts of animals and serve as symbionts (''Wolinella'' spp. in cattle) or pathogens (''Helicobacter'' spp. in the stomach, ''Campylobacter'' spp. in the duodenum). Many Campylobacterota are motile with flagella. Numerous environmental sequences and isolates of Campylobacterota have also been recovered from hydrothermal vents and cold seep habitats. Examples of isolates include ''Sulfurimonas autotrophica'', ''Sulfurimonas paralvinellae'', ''Sulfurovum lithotrophicum'' and ''Nautilia profundicola''. A member of the phylum Campylobacterota occurs as an endosymbiont in the large gills of the deepwater sea snail ''Alviniconcha hessleri''.
