The results of the complex parasitological studies conducted in the wild birds of hunting interest as well as domestic birds demonstrates that the phenomenon of the poliparasitism is a static one, although the poliparasitic quantitative and qualitative structure is continuously changing. This is due to instantaneous contact of the wild birds with the domestic ones, irregular deparasiting of domestic animals and their crates, reduced areas for animals breading and maintenance that ensures the permanent contact with the wild birds as the infestation source. The findings of the study on the diversity of the ectoparasitic fauna in wild birds from various anthropic biotopes of Moldova revealed that the wild and domestic birds are infested with multiple parasites and that the most identified parasitoses are common for major birds of hunting interest as well as for the domestic birds.
