[The way of penetration of first stage larvae of Elaphostrongylus cervi (Nematoda, Protostrongylidae) to the intermediate host and their development to the invasive stage].

The aim of the study was the way of penetration of the first stage larvae of Elaphostrongylus cervi to the intermediate host and their development to the invasive stage. The first stage larvae of E. cervi penetrate to the body of a snail by the epithelium of its foot, and localise in tissue of muscles. The period of their development to the second stage is 7 to 9 days, and to the third stage is 21 to 28 days.
