Fusobacteriota
Fusobacteriota are obligately anaerobic non-sporeforming Gram-negative bacilli. Since the first reports in the late nineteenth century, various names have been applied to these organisms, sometimes with the same name being applied to different species. More recently, not only have there been changes to the nomenclature, but also attempts to differentiate between species which are believed to be either pathogenic or commensal or both. Because of their asaccharolytic nature, and a general paucity of positive results in routine biochemical tests, laboratory identification of the Fusobacteriota has been difficult. However, the application of novel molecular biological techniques to taxonomy has established a number of new species, together with the subspeciation of ''Fusobacterium necrophorum'' and ''F. nucleatum'', and provided new methods for identification. The involvement of Fusobacteriota in a wide spectrum of human infections causing tissue necrosis and septicaemia has long bee ...

List Of Bacterial Orders
This article lists the orders of the Bacteria. The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) and National Center for Biotechnology Information (NCBI) and the phylogeny is based on 16S rRNA-based LTP release 132 by The All-Species Living Tree Project. Phylogeny National Center for Biotechnology Information (NCBI) taxonomy was initially used to decorate the genome tree via tax2tree. The 16S rRNA-based Greengenes taxonomy is used to supplement the taxonomy particularly in regions of the tree with no cultured representatives. List of Prokaryotic names with Standing in Nomenclature (LPSN) is used as the primary taxonomic authority for establishing naming priorities. Taxonomic ranks are normalised using phylorank and the taxonomy manually curated to remove polyphyletic groups. Cladogram was taken from GTDB release 07-RS207 (8th April 2022).

The All-Species Living Tree Project
The All-Species Living Tree' Project is a collaboration between various academic groups/institutes, such as ARB Project, ARB, SILVA rRNA database project, and List of Prokaryotic names with Standing in Nomenclature, LPSN, with the aim of assembling a database of 16S ribosomal RNA, 16S rRNA sequences of all validly published species of ''Bacteria'' and ''Archaea''. At one stage, 23S ribosomal RNA, 23S sequences were also collected, but this has since stopped. Currently there are over 10,950 species in the aligned dataset and several more are being added either as new species are discovered or species that are not represented in the database are sequenced. Initially the latter group consisted of 7% of species. Similar (and more recent) projects include the Genomic Encyclopedia of Bacteria and Archaea (GEBA), which focused on whole genome sequencing of bacteria and archaea. Tree The tree was created by maximum likelihood analysis without bootstrap: consequently accuracy is traded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fusiform
Fusiform means having a spindle-like shape that is wide in the middle and tapers at both ends. It is similar to the lemon-shape, but often implies a focal broadening of a structure that continues from one or both ends, such as an aneurysm on a blood vessel. Examples * Fusiform, a body shape common to many aquatic animals, characterized by being tapered at both the head and the tail * Fusiform, a classification of aneurysm * Fusiform bacteria (spindled rods, that is, fusiform bacilli), such as the Fusobacteriota * Fusiform cell (biology) * Fusiform face area, a part of the human visual system which seems to specialize in facial recognition * Fusiform gyrus, part of the temporal lobe of the brain * Fusiform muscle, where the fibres run parallel along the length of the muscle * Fusiform neuron, a spindle-shaped neuron A neuron, neurone, or nerve cell is an electrically excitable cell that communicates with other cells via specialized connections called synapses.

Fusobacterium Perfoetens
''Fusobacterium'' is a genus of anaerobic, Gram-negative, non-sporeforming bacteria belonging to Gracilicutes. Individual cells are slender, rod-shaped bacilli with pointed ends. Strains of ''Fusobacterium'' cause several human diseases, including periodontal diseases, Lemierre's syndrome, and topical skin ulcers. Although older sources state that ''Fusobacterium'' is part of the normal flora of the human oropharynx, the current consensus is that ''Fusobacterium'' should always be treated as a pathogen. ''F. prausnitzii'', a gut commensal associated with healthy patients, was completely reclassified as ''Faecalibacterium'' (''Clostridiales'':''Ruminococcaceae'') in 2002. Clinical relevance ''Fusobacterium'' is often associated with ulcerative colitis. Research of colon cancer has also shown an overrepresentation of ''Fusobacterium'', both in feces of patients and tumor issue itself.

Streptobacillus
''Streptobacillus'' is a genus of fastidious microaerophilic gram-negative bacteria, which grow in culture as rods in chains. Species associated with infection - ''S. moniliformis'' Reported susceptibilities and therapies - penicillin, erythromycin Diseases Associated infections: the Haverhill fever form of rat bite fever. (Notes ''Spirillum minus'' is also an agent of rat bite fever, in the form known as sodoku.) Haverhill fever, which is characterized by fever, rash, chills, headache, vomiting, muscle pain, arthritis, and bacteremia, and by weight loss and diarrhea in children. Commentary Rat bite fever is caused by either '' Streptobacillus moniliformis'' or '' Spirillum minor''. The incidence of rat-bite fever is highest in urban areas with poor sanitation where the rat population is high, however in recent times cases have also been attributed to occupational contact with rodents such as pet shop employees or laboratory workers or through pet ownership.

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 lipo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
