Study of the saiga helminth fauna and Ural sheep in the western region of Kazakhstan.

Background: Contact between wild (saiga) and domestic (sheep) animals on pastures results in a composite community of helminths. Wild animals like saigas are vulnerable to parasites and the diseases they transmit are fatal. Adults may be less susceptible to infection than their offspring but remain a dangerous source of parasite spread.
