[The effect of anthelmintics on the viability of Taenia saginata oncospheres]

The viability of taeniid eggs has been investigated by means of methylene blue staining. In patients with niclosamide treatment the degree of dead taeniid eggs was 90-100% (19 of 25 cases). In patients without therapy the taeniid eggs were vital in 22 of 25 cases. Therefore recognition and treatment of all taeniid hosts is a way to reduce the taeniosis-cysticercosis extent.
