There are several species of tapeworms, and each uses a different intermediate host to infect a pet. Fleas, small rodents, rabbits or larger animals such as deer and sheep are the hosts that transmit the worms to dogs or cats. Pets infected with tapeworms do not normally lose weight or display symptoms of illness.
The Glut1 protein is also found in red blood cells (erythrocytes). Testing is available on a clinical basis to assess erythrocyte glucose transporter activity, which is reduced by approximately 50 percent in individuals with Glut1 deficiency syndrome.
GGT is an enzyme that is naturally occurring in the blood. When damage, disease, or disorder occur in the liver, GGT will automatically increase, especially if the injury affects the bile duct. However, an increase in the enzyme is possible when there is no damage to the liver.
