[Supervision of the sanitary-helminthological state of soil in the inhabited areas of Moscow].

In accordance with the normative and methodical documents [3-5, 7-9], a complex of organizational, sanitary, and antiepidemic actions is performed to protect soil from causative agents of parasitic diseases in Moscow. About 2000 soil samples are annually taken from the playgrounds of children's educational establishments and apartment houses and tested. The soil contamination averages 3.

Immunostimulatory complexes containing Eimeria tenella antigens and low toxicity plant saponins induce antibody response and provide protection from challenge in broiler chickens.

Immunostimulating complexes (ISCOMs) are unique multimolecular structures formed by encapsulating antigens, lipids and triterpene saponins and are one of the most successful antigen delivery systems for microbial antigens. In the current study, both the route of administration and the antigen concentration of ISCOMs, containing Eimeria tenella antigens and saponins from native plants, were evaluated in their ability to stimulate humoral immunity and to protect chickens against a challenge infection with E. tenella.

[Immunostimulating activity of a saponin-containing extract of Saponaria officinalis].

The immunostimulating activity of saponin-containing extract of Saponaria officinalis has been studied. Use of an S. officinalis extract in a concentration close to the critical concentration of saponin micella formation increased the immunogenicity of viral glycoproteins.
