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.

Answers. Best Answer: It must be kept constant because cells need glucose for energy, and thus to stay alive. If glucose levels fell, then cells might start dying due to a very simple lack of food. Most body cells cannot store glucose for food. Only muscle and liver cells can.nswers. Best Answer: It must be kept constant because cells need glucose for energy, and thus to stay alive.
