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.

Insulin levels in the blood stream are carefully calibrated to keep the blood glucose just right. High insulin levels drive sugar into muscle, fat and liver cells where it is stored for future use. Low insulin levels allow sugar and other fuels to be released into the blood stream.
