Seasonal dynamics of the invasive cycle of nematodes and acanthocephala in the wild (Anas platyrhynchos) and domestic duck (Anas platyrhynchos)

Seasonal dynamics of the invasive cycle of nematodes (Tetrameres fissispina, Porrocaecum crassum, Epomidiostomum uncinatum, Amidostomum acutum, Thominx contorta) and acanthocephala (Filicollis anatis, Polymorphus minutus) of wild and domestic ducks from the natural focal region of the East Slovakia...

Summary:Seasonal dynamics of the invasive cycle of nematodes (Tetrameres fissispina, Porrocaecum crassum, Epomidiostomum uncinatum, Amidostomum acutum, Thominx contorta) and acanthocephala (Filicollis anatis, Polymorphus minutus) of wild and domestic ducks from the natural focal region of the East Slovakia Lowland (Slovak Republic, CSFR) has been analyzed. The nematodes occurred in wild duck at relatively low level all the year round. The mean values of extensity of invasion did not exceed 50 per cent and those of intensity of invasion 9 specimen. In domestic ducks the nematodes occurred mostly from March to October with 25 per cent extensity but with higher intensity of invasion (up to 30 specimen) than in wild ducks. Curves of seasonal dynamics of the invasive cycle in both host groups showed almost identical course. Acanthocephala were recorded from spring to autumn with low extensity and intensity of invasion, especially in domestic duck. The highest occurrence of thorny-headed worms was observed from June to October.
