Abstract:
The first clinical isolation of Eggerthia catenaformis, a rare novel bacteria from gingival crevicular fluid (GCF) and dental plaque samples of chronic periodontitis patients, is described in this article. This bacterium is a strict anaerobic nonspore-forming Gram-positive bacillus usually associated with brain abscess, intestinal, and pleural infections. Isolation of such bacteria from GCF and dental plaque samples of chronic periodontitis patients would be a rare novel case of its own, depicting possible oro-systemic relationship and possible evolution of oral dysbiosis.

Accelerating Fluids
The motion of the liquid within this infinitesimal cylinder is considered to obtain the pressure difference. Three vertical forces act on this liquid:
Cerebrospinal Fluid
CSF Production
CSF is produced mainly in the choroid plexus, a network of capillaries and ependymal cells located within the ventricular system of the brain....
Fluid Pressure
According to Pascal's law, a fluid at rest will generate equal pressure in all directions. This pressure is measured as a force per unit area, and its magnitude depends on the fluid's specific...
Characteristics of Fluids
Fluids, which include both liquids and gases, are substances that deform continuously under shearing stress. For example, water and oil are liquids with molecules that can...
