Capnocytophaga
''Capnocytophaga'' is a genus of Gram-negative bacteria. Normally found in the oropharyngeal tract of mammals, they are involved in the pathogenesis of some animal bite wounds and periodontal diseases. Taxonomy The term ''Capnocytophaga'' comes from "capno-" for its dependence on CO2 and "cytophaga" for its flexibility and mobility shift (gliding motility). It belongs to the family Flavobacteriaceae, order Flavobacteriales. This genus includes eight different species: ''C. ochracea'', ''C. gingivalis'', ''C. granulosa'', ''C. haemolytica'', ''C. sputigena'', ''C. leadbetteri'' (isolated oral cavity of humans), ''C. canimorsus'', and ''C. cynodegmi'' (isolated from the oral cavity of animals). Many strains have also been described whose classification remains uncertain. Bacteriological isolation and identification ''Capnocytophaga'' spp. are fusiform Gram-negative bacilli, and are part of the oral commensal flora. Microscopic observation revealed a high degree of polymorphism ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flavobacteriaceae
The family Flavobacteriaceae is composed of environmental bacteria. Most species are aerobic, while some are microaerobic to anaerobic; for example '' Capnocytophaga'' and ''Coenonia''.

Bacteroidota
The phylum Bacteroidota (synonym Bacteroidetes) is composed of three large classes of Gram-negative, nonsporeforming, anaerobic or aerobic, and rod-shaped bacteria that are widely distributed in the environment, including in soil, sediments, and sea water, as well as in the guts and on the skin of animals. Although some ''Bacteroides'' spp. can be opportunistic pathogens, many ''Bacteroidota'' are symbiotic species highly adjusted to the gastrointestinal tract. ''Bacteroides'' are highly abundant in intestines, reaching up to 1011 cells g−1 of intestinal material. They perform metabolic conversions that are essential for the host, such as degradation of proteins or complex sugar polymers. ''Bacteroidota'' colonize the gastrointestinal tract already in infants, as non-digestible oligosaccharides in mother milk support the growth of both '' Bacteroides'' and '' Bifidobacterium'' spp. ''Bacteroides'' spp. are selectively recognized by the immune system of the host through specif ...

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 References {{Reflist Geometric shapes See also * Streamliner A streamliner is a vehicle incorporating streamlining in a shape providing reduced a ...

Commensalism
Commensalism is a long-term biological interaction ( symbiosis) in which members of one species gain benefits while those of the other species neither benefit nor are harmed. This is in contrast with mutualism, in which both organisms benefit from each other; amensalism, where one is harmed while the other is unaffected; parasitism, where one is harmed and the other benefits, and parasitoidism, which is similar to parasitism but the parasitoid has a free-living state and instead of just harming its host, it eventually ends up killing it. The commensal (the species that benefits from the association) may obtain nutrients, shelter, support, or locomotion from the host species, which is substantially unaffected. The commensal relation is often between a larger host and a smaller commensal; the host organism is unmodified, whereas the commensal species may show great structural adaptation consistent with its habits, as in the remoras that ride attached to sharks and other fish ...
