The virulence of specific strains in humans and other animals is frequently serovar specific. Salmonella enterica serovar Typhi causes typhoid fever in humans, but no disease is associated with experimental infections of mice (8).
Glucose is the primary energy source for the body's cells and the only energy source for the brain and nervous system. A steady supply must be available for use, and a relatively constant level of glucose must be maintained in the blood. A few different protocols may be used to evaluate the glucose level in the blood.lucose is the primary energy source for the body's cells and the only energy source for the brain and nervous system.

Homeostatic mechanisms normally maintain the plasma glucose concentration within narrow limits despite major fluctuations in supply and demand. There is increasing evidence that the growth hormone (GH)-insulin-like growth factor (IGF) axis may play an important role in glucose metabolism.omeostatic mechanisms normally maintain the plasma glucose concentration within narrow limits despite major fluctuations in supply and demand.
