Helicobacter anseris is a bacterium in the Helicobacteraceae family, Campylobacterales order. It is Gram-negative, microaerophilic, spiral to curve-shaped, being first isolated from the faeces of geese. [1]
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.
Acidobacteriota is a phylum of Gram-negative bacteria. Its members are physiologically diverse and ubiquitous, especially in soils, but are under-represented in culture.
Thermus is a genus of thermophilic bacteria. It is one of several bacteria belonging to the Deinococcota phylum. Thermus species can be distinguished from other genera in the family Thermaceae as well as all other bacteria by the presence of eight conserved signature indels (CSIs) found in proteins such as adenylate kinase and replicative DNA helicase as well as 14 conserved signature proteins (CSPs) that are exclusively shared by members of this genus.
Sphingomonadaceae are a gram-negative bacterial family of the Alphaproteobacteria. An important feature is the presence of sphingolipids in the outer membrane of the cell wall. The cells are ovoid or rod-shaped. Others are also pleomorphic, i.e. the cells change the shape over time. Some species from Sphingomonadaceae family are dominant components of biofilms.
Campylobacterota are a phylum of bacteria. All species of this phylum are Gram-negative.
Bacterial phyla constitute the major lineages of the domain Bacteria. While the exact definition of a bacterial phylum is debated, a popular definition is that a bacterial phylum is a monophyletic lineage of bacteria whose 16S rRNA genes share a pairwise sequence identity of ~75% or less with those of the members of other bacterial phyla.
Agrococcus is a genus in the phylum Actinomycetota (Bacteria).
Helicobacter pullorum is a bacterium in the Helicobacteraceae family, Campylobacterales order. It was isolated from the liver, duodenum, and caecum of broiler and layer chickens, and from humans with gastroenteritis. It is a nongastric urease-negative Helicobacter species colonizing the lower bowel.
Helicobacter canis is a bacterium in the Helicobacteraceae family, Campylobacterales order. Its type strain is NCTC 12739T. It colonises the lower bowel, but is also present in cases of hepatitis. Besides infecting dogs, this bacterium is known to cause infections in immunocompromised humans.
Helicobacter hepaticus is a bacterium in the Helicobacteraceae family, Campylobacterales order.
Helicobacter bilis is a bacterium in the Helicobacteraceae family, Campylobacterales order. It is a fusiform bacterium with three to 14 multiple bipolar sheathed flagella and periplasmic fibers wrapped around the cell. It is resistant to cephalothin and nalidixic acid, but sensitive to metronidazole. Like Helicobacter hepaticus, it colonizes the bile, liver, and intestine of mice, and is associated with multifocal chronic hepatitis and hepatocellular tumors.
Leptospirillum ferriphilum is an iron-oxidising bacterium. It is one of the species responsible for the generation of acid mine drainage. It is of particular relevance in South African commercial biooxidation tanks operating at 40 °C.
Helicobacter acinonychis is a bacterium in the Helicobacteraceae family, Campylobacterales order. It was first isolated from cheetahs with gastritis, so has been associated with this disease in this particular species and others of its kind. It is Gram-negative, spiral-shaped, and grows under microaerophilic conditions. The type strain is 90-119.
Helicobacter canadensis is a bacterium in the Helicobacteraceae family, Campylobacterales order, first isolated from humans with diarrhea. Its genome has been sequenced.
Helicobacter trogontum is a bacterium in the Helicobacteraceae family, Campylobacterales order. It was first isolated from rat intestine. It is Gram-negative, its cells are rod-shaped with pointed ends, and its protoplasmic cylinder is entwined with periplasmic fibers. It is microaerophilic. The type strain is LRB 8581.
Helicobacter pametensis is a bacterium in the Helicobacteraceae family, Campylobacterales order. It was first isolated from bird and swine faeces. Its cells are motile and possess one subterminal sheathed flagellum at each end.
Helicobacter brantae is a bacterium in the Helicobacteraceae family, Campylobacterales order. It is Gram-negative, microaerophilic, spiral to curve-shaped, being first isolated from the faeces of geese.
Cyclobacterium is a mesophilic, neutrophilic, chemoorganotrophic and aerobic bacterial genus from the family of Cyclobacteriaceae. Cyclobacterium bacteria occur in marine habitats
Janibacter is a genus of Gram positive, nonmotile, non-sporeforming bacteria. The genus name is derived from the two-faced Roman god Janus, referring to the fact that the cells of the original strain could be rod-shaped or coccoid.
Helicobacter typhlonius is a Gram-negative bacterium and opportunistic pathogen found in the genus Helicobacter. Only 35 known species are in this genus, which was described in 1982. H. typhlonius has a small number of close relatives, including Helicobacter muridarum, Helicobacter trogontum, and Helicobacter hepaticus, with the latter being the closest relative and much more prevalent.
