Abstract
In a previous study, a single external treatment with Ivomec appeared to be more effective than Neguvon treatment. In this study the anti-endoparasitic qualities of external application of Ivomec were investigated, together with the effectiveness of a combined Neguvon and Ivomec treatment. After 3 treatments, all mice were mite- and worm-free: they remained free of ectoparasites until 18 weeks after the last treatment; eggs of endoparasites reappeared 9 weeks after the last treatment.
