Cardiobacteriales
The Cardiobacteriaceae are a family of Pseudomonadota, given their own order. They are Gram-negative Gram-negative bacteria are bacteria that do not retain the crystal violet stain used in the Gram staining method of bacterial differentiation. They are characterized by their cell envelopes, which are composed of a thin peptidoglycan cell wa ... and rod-shaped, with diameters around 0.5 to 1.7 μm and lengths from 1–6 μm.George M.

Dichelobacter
''Dichelobacter nodosus'', formerly ''Bacteroides nodosus'', is a Gram-negative, obligate anaerobe of the family Cardiobacteriaceae. It has polar fimbria (bacteriology), fimbriae and is the causative agent of ovine foot rot as well as interdigital dermatitis in cattle, interdigital dermatitis. It is the lone species in the genus ''Dichelobacter''. ''Dichelobacter nodosus'', formerly ''Bacteroides nodosus'', is a gram negative, rod shaped, obligate anaerobe of the family Cardiobacteriaceae. It has polar fimbriae epitomes that separate the bacteria into multiple serogroups. ''D. nodosus,'' along with ''Fusobacterium necrophorum,'' co-exist as the causative agents of ovine foot rot and interdigital dermatitis in ungulates globally, especially in temperate zones. Clinical signs can vary into two categories; virulent and benign, with the distinction between the two varying dependent on location. Treatment options include footbaths, parenteral administration of long-acting antimicrob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gammaproteobacteria
Gammaproteobacteria is a class of bacteria in the phylum Pseudomonadota (synonym Proteobacteria). It contains about 250 genera, which makes it the most genera-rich taxon of the Prokaryotes. Several medically, ecologically, and scientifically important groups of bacteria belong to this class. It is composed by all Gram-negative microbes and is the most phylogenetically and physiologically diverse class of Proteobacteria. These microorganisms can live in several terrestrial and marine environments, in which they play various important roles, including ''extreme environments'' such as hydrothermal vents. They generally have different shapes - rods, curved rods, cocci, spirilla, and filaments and include free living bacteria, biofilm formers, commensals and symbionts, some also have the distinctive trait of being bioluminescent. Metabolisms found in the different genera are very different; there are both aerobic and anaerobic (obligate or facultative) species, chemolithoautotroph ...

Bacteria
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria are vital in many stages of the nutrient cycle by recycling nutrients such as the fixation of nitrogen from the atmosphere. The nutrient cycle includes the decomposition of dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulphide and methane, to energy. Bacteria also live in symbiotic and parasitic re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudomonadota
Pseudomonadota (synonym Proteobacteria) is a major phylum of Gram-negative bacteria. The renaming of phyla in 2021 remains controversial among microbiologists, many of whom continue to use the earlier names of long standing in the literature. The phylum Proteobacteria includes a wide variety of pathogenic genera, such as '' Escherichia'', '' Salmonella'', '' Vibrio'', '' Yersinia'', '' Legionella'', and many others.Slonczewski JL, Foster JW, Foster E. Microbiology: An Evolving Science 5th Ed. WW Norton & Company; 2020. Others are free-living (non parasitic) and include many of the bacteria responsible for nitrogen fixation. Carl Woese established this grouping in 1987, calling it informally the "purple bacteria and their relatives". Because of the great diversity of forms found in this group, it was later informally named Proteobacteria, after Proteus, a Greek god of the sea capable of assuming many different shapes (not after the Proteobacteria genus ''Proteus''). In 2021 the In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rappaport (bacterium)
The Rappaport family (Hebrew: רפפורט; Yiddish: ראפאפארט) is a prominent Kohanic rabbinic family, who are generally considered to possess the oldest and best recorded Kohanic pedigree. The modern origins of the family can be traced back to R. Meshulam Jekuthiel HaKohen Rappa (d. 1450) who settled in Porto, Mantua, Italy after the Jews were expelled from his hometown of Mainz, Holy Roman Empire. From the 17th century and onward, the Rappaport family occupied some of the most prestigious rabbinic positions in Europe, specifically in Eastern Europe. The Rapoport-Bick rabbinic dynasty is a branch of the Rappaport family. History By the middle of the 17th century authors belonging to the Rappaport family were living in Poland and Lithuania, and were particularly concentrated in Krakow and Lviv; in the latter place, in 1584, was born the famous Talmudist R. Abraham Rappaport and R. Simhah Rappaport in 1650, the latter's son, R. Khaim Rappaport was the progenitor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gram-negative
Gram-negative bacteria are bacteria that do not retain the crystal violet stain used in the Gram staining method of bacterial differentiation. They are characterized by their cell envelopes, which are composed of a thin peptidoglycan cell wall sandwiched between an inner cytoplasmic cell membrane and a bacterial outer membrane. Gram-negative bacteria are found in virtually all environments on Earth that support life. The gram-negative bacteria include the model organism ''Escherichia coli'', as well as many pathogenic bacteria, such as '' Pseudomonas aeruginosa'', '' Chlamydia trachomatis'', and '' Yersinia pestis''. They are a significant medical challenge as their outer membrane protects them from many antibiotics (including penicillin), detergents that would normally damage the inner cell membrane, and lysozyme, an antimicrobial enzyme produced by animals that forms part of the innate immune system. Additionally, the outer leaflet of this membrane comprises a complex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
