RESUMO
Lungworm infection is caused by a Dictyocaulus filaria nematode parasitizing the bronchi and bronchioles of sheep and goats. Various anthelmintics, including albendazole, levamisole, fenbendazole, ivermectins, and others, are used to treat the animals. The aim of this investigation was to study the impact of lungworm infestation on the biochemical parameters of animals during combination treatment with albendazole and T- and B-activin. Experiments were carried out in 20 uninfected mongrel lambs aged 4-5 months. Infectious D.filaria larvae were given with water to 15 lambs once orally at a dose of 1000 larvae per head. 5 uninfected lambs served as a control group. The time course of changes in serum bio- chemical parameters was studied in animals. Treatment with Albena in combination with T- and B-activin in lambs ex- perimentally infested with lungworm was found to restore their biochemical reactivity. After sheep treatment with Albena alone, biochemical parameters were noted to tend to normalize, but their normal full recovery did not take place.
