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.

Glucose is important to the cells of the body, particularly the brain, as an energy source. However, the level of glucose in the blood must be regulated so that it does not rise too high. When the bloodstream contains glucose the pancreas is stimulated to produce the hormone insulin.Insulin causes glucose to be usable by the body cells and excess to be stored in the liver and muscles as glycogen.lycogen is stored in the liver and in muscles and can be converted back to glucose when needed by the body. Diabetes. A disease in which there is too much sugar in the blood. It results in tiredness, thirst and the production of a large volume of urine.
