The Aquificae currently contain 15 genera and 42 validly published species. The phylum comprises a single class and two orders. Aquificales consists of the families Aquificaceae and Hydrogenothermaceae, while the Desulfurobacteriaceae are the only family within the Desulfobacteriales.

Eubacteria Photo by: Sebastian Kaulitzki Bacteria are microscopic organisms that comprise the domain Eubacteria. A domain is the highest grouping of organisms, superseding the level of kingdom in the classical Linnaean system of biological classification. ~ Page 2 A unique group of ~ that bears mentioning is the mycoplasmas.

Historically, bacteria were first classified as plants constituting the class Schizomycetes, which along with the Schizophyceae (blue-green algae/Cyanobacteria) formed the phylum Schizophyta, then in the phylum Monera in the kingdom Protista by Haeckel in 1866, comprising Protogens, Protamaeba, Vampyrella, Protomonae, and Vibrio, but not Nostoc and other cyanobacteria, which were classified with algae, later reclassified as the Prokaryotes by Chatton.

The term "bacteria" was traditionally applied to all microscopic, single-cell prokaryotes. However, molecular systematics showed prokaryotic life to consist of two separate domains, originally called Eubacteria and Archaebacteria, but now called Bacteria and Archaea that evolved independently from an ancient common ancestor.

Chlamydia is a common sexually transmitted infection (STI) caused by bacteria. People who have chlamydia often don’t have outward symptoms in the early stages. That might make you think you shouldn’t worry. However, chlamydia can cause health problems later, including preventing women from ...

Being a deep branching phylum (cf. Bacterial phyla) its classification was analysed in Volume One of Bergey's Manual of Systematic Bacteriology and included a single class with the same name, the class Chloroflexi.

Dictyoglomus thermophilum. Description and significance. Dictyoglomus thermophilum is light grey, anaerobic, extremely thermophilic, rod-shaped bacterium first isolated from a slightly alkaline hot spring (pH 7.2, 100% N2) in Japan, 1985.

The Firmicutes (Latin: firmus, strong, and cutis, skin, referring to the cell wall) are a phylum of bacteria, most of which have Gram-positive cell wall structure. A few, however, such as Megasphaera, Pectinatus, Selenomonas and Zymophilus, have a porous pseudo-outer membrane that causes them to stain Gram-negative.

Gram-positive organisms stain purple with a differential staining procedure developed in 1884 by Christian Gram. This procedure identifies cells that have a thick cell wall of peptidoglycan. While many Firmicutes stain Gram-positive, some do not.

Nitrospira is part of a nitrification process which is important in the biogeochemical nitrogen cycle. Nitrification is the oxidation of ammonia to nitrite by autotrophic bacteria of the genus Nitrosomonas and oxidation of the nitrite to nitrate by bacteria in the genus Nitrobacter or Nitrospira.

Proteobacteria is a major phylum of gram-negative bacteria. They include a wide variety of pathogens, such as Escherichia, Salmonella, Vibrio, Helicobacter, Yersinia, Legionellales, and many other notable genera. Others are free-living (non-parasitic), and include many of the bacteria responsible for nitrogen fixation.

Spirochete, (order Spirochaetales), also spelled spirochaete, any of a group of spiral-shaped bacteria, some of which are serious pathogens for humans, causing diseases such as syphilis, yaws, Lyme disease, and relapsing fever.

Bacillus, (genus Bacillus), any of a group of rod-shaped, gram-positive, aerobic or (under some conditions) anaerobic bacteria widely found in soil and water. The term bacillus has been applied in a general sense to all cylindrical or rodlike bacteria.

Thermus-like bacteria have been found in both shallow and deep-sea marine hydrothermal systems, as well as in low saline solfataric springs.The Thermus strain T. aquaticus was first isolated in Yellowstone National Park from neutral and alkaline springs and has since then also been isolated from hot springs found in Iceland.
