The oral cavity of dogs can be exposed to a variety of bacteria, parasites and viruses from their environment and it is not surprising that these induce an inflammatory reaction in the periodontium. [3] The accumulation of these bacteria, along with extracellular polysaccharides and salivary glycoproteins, leads to the formation of plaque. [11]
Volvox is a polyphyletic genus in the volvocine green algae clade. [2] Each mature Volvox colony is composed of up to thousands of cells from two differentiated cell types: numerous flagellate somatic cells and a smaller number of germ cells lacking in soma that are embedded in the surface of a hollow sphere or coenobium containing an ...
Volvox carteri [1] is a species of colonial green algae in the order Volvocales. [2] The V. carteri life cycle includes a sexual phase and an asexual phase.V. carteri forms small spherical colonies, or coenobia, of 2000–6000 Chlamydomonas-type somatic cells and 12–16 large, potentially immortal reproductive cells called gonidia.

The definition of prebiotics and the food ingredients that can fall under this classification, has evolved since its first definition in 1995. [3] In its earliest definition, the term prebiotics was used to refer to non-digestible food ingredients that were beneficial to the host through their selective stimulation of specific bacteria within the colon.
Dogs get ample correct nutrition from their natural, normal diet; wild and feral dogs can usually get all the nutrients needed from a diet of whole prey and raw meat. In addition, a human diet is not ideal for a dog: the concept of a "balanced" diet for a facultative carnivore like a dog is not the same as in an omnivorous human. Dogs will ...
For example, salt provides sodium and chloride, both essential nutrients, but will cause illness or even death in too large amounts. Dietary fibre is a carbohydrate (polysaccharide or oligosaccharide) that is incompletely absorbed in some animals.
Multicellular Volvox shows a higher level of complexity, with differentiation between interior germ cells and somatic cells dedicated to propulsion. Despite lacking a central nervous system to coordinate its cells, Volvox exhibits accurate phototaxis. This is also achieved by an adaptive response to changing light levels, with a response time ...
Not only are the microbes influenced by the dog's environment, but they are also affected by the macronutrient content of the dog's diet. [78] The populations present and health status of the microbiota found within the gut can alter the physiological and metabolic functions of the dog, which then subsequently affects susceptibility to disease ...
