Abstract

The infectivity of Taenia saginata eggs exposed to environmental conditions on a natural soil surface in Denmark was studied by feeding the eggs to susceptible calves, followed by determination of the number of cysts developed. The results indicated that a small proportion of the eggs remained infective for 6 1/2 months, but not for 9 1/2 months when deposited in May 1986, and for 5 1/2 months but not for 8 1/2 months when desposited in September 1987. Viability of eggs was tested in vitro and compared with infectivity obtained in calves.

Keywords: Cysticercus bovis, egg survival, infectivity, viability, soil surface, climate
