[Cadaverine and its possible role in parasite and host interrelations in ascaridiasis]

A comparative study of the formation process of cadaverine in tissues of ascarides, intestine and liver of hen was conducted. Data are given on the activity, pH-optimum of lysine decarboxylase obtained from tissues of helminth and its host. The question on a toxic role of cadaverine during helminthiasis is considered. It has been concluded that the accumulation of cadaverine in the host's intestine can break the permeability of the intestine walls and favour the penetration of toxins of helminths into the host's organism.
