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.

The brain and the red blood cells need glucose as an energy source, since they cannot use fat, protein, or other forms of energy for this purpose. It is for this reason that glucose in the blood must be constantly maintained at an optimum level.. Introduction.

They exist in many forms and are mainly found in starchy foods such as bread, pasta, and rice, as well as in some beverages, e.g. fruit juices and sugar-sweetened drinks.
