Występowanie larw nicieni z rodziny Protostrongylidae w ślimakach lądowych na fermie jeleniowatych w Kosewie

In 1995 on the area of deer farm in Kosewo 1302 specimens of terrestrial snails of the following species were collected: Succinea putris (1220), Zonitoides nitidus (58), Zenobiella rubiginosa (20), Arion circumscriptus (4). These snails were examinated by compressor method. Only S. putris were infected by larvae of two species of Protostrongylidae. Larvae were found only in snails collected from red deer stockyards, however, none snail collected in fallow deer stockyards was infected. The highest extensiveness of invasion of snails by Elaphostrongylus cervi larvae was 5%, and the maximal intensity reached 105 larvae. Larvae of Varestrongylus sagittatus occurred occasionaly in 0,4% of snails, with the mean intensity of 3 larvae.
