Hosts
Definitive host: Dogs and foxes.
Intermediate host: Cattle, sheep, pig, horses and man.
Identification
T. multiceps are around 5cm in length.
Life Cycle
The intermediate host is infected via ingestion of the parasite eggs. These eggs hatch in the small intestine. The parasite the migrates to the spinal cord and brain via the blood stream. The definitive host becomes infected when it eats the spinal bord, or brain of the intermediate host.

Family | Taeniidae |
Genus | Taenia |
Species | T. serialis' |

Hosts
Definitive host:Dog.
Intermediate host: Rabbit.
Identification
T. serialis is around 0.5m, with two prominent rows of hooks.
Life Cycle
The intermediate host is infected through ingestion of the tapeworm egg, which is shed by the dog, which acts as the definitive host. These develop and form cysts in the intermuscular connective tissues of rabbits, often causing a soft subdermal swelling. . The definitive host then becomes infected through ingestion of the metacestode.
