Pig as a Favorable Animal for Taenia Saginata Asiatica Infection
The epidemiology of Taenia saginata in some parts of Asia is confusing, in that beef does not appear to be the source of infection. In some areas, beef is either not available or not eaten raw, whereas pork at times is eaten uncooked. In light of this situation, we have exposed pigs and other animal...

Summary: | The epidemiology of
Taenia saginata in some parts of Asia is confusing, in that beef does not appear to be the source of infection. In some areas, beef is either not available or not eaten raw, whereas pork at times is eaten uncooked. In light of this situation, we have exposed pigs and other animals to infection with strains of
T. saginata to establish their ability to serve as intermediate hosts. Eggs of Taiwan
Taenia, Korea
Taenia, Indonesia
Taenia, Thailand
Taenia, Philippines
Taenia, Ethiopia
Taenia, and Madagascar
Taenia were fed to 83 pigs of three strains: 43 Small-Ear Miniature (SEM), 34 Landrace Small-Ear Miniature (L-SEM), and 6 Duroc-Yorkshire-Landrace (DYL). We also fed the eggs to 10 Holstein calves, 17 Sannean goats, and 4 monkeys (
Macaca cyclopis). We succeeded in infecting SEM (infection rate 88%, cysticercus recovery rate 19.1%), L-SEM (83%, 1.1%), and DYL (100%, 0.3%) pigs with Taiwan
Taenia; SEM (100%, 1.7%), L-SEM (100%, 5.6%), and DYL (100%, 0.06%) pigs with Korea
Taenia; SEM (100%, 22%) and L-SEM (100%, 1.6%) pigs with Indonesia
Taenia; SEM (75%, 0.06%) pigs with Thailand
Taenia SEM (100%, 11%) pigs with Philippines
Taenia; SEM (80%, 0.005%) pigs with Ethiopia
Taenia; SEM (100%, 0.2%) pigs with Madagascar
Taenia. Holstein calves became infected with
Taenia from Taiwan (100%, 1.1%), Korea (100%, 0.03%), Thailand (100%, 0.2%), and the Philippines (100%, 6%); however, the cysticerci of
Taenia from Korea, Thailand, and the Philippines were degenerated and/or calcified. Sannean goats became infected with
Taenia from Taiwan (33%, 0.01%) and Korea (50%, 0.02%), while monkeys became infected with
Taenia from Taiwan (50%, 0.01%). However, the cysticerci were degenerated and/or calcified. Therefore, these strains of pig seem to be favorable animal models for experimental studies of
T. saginata-like tapeworms, with the SEM pig the most favorable. |
