[The reproductive activity of Trichinella spiralis in the early stages of cultivation on artificial nutrient media].

Reproductive activity of mature Trichinella spiralis was studied during its cultivation in three nutrient media. Most active hatching of Trichinella larvae was observed in Erl's saline, less active in Eagle's medium and in the lactalbumin hydrolyzate medium. In Erl's medium the hatching of larvae accounted for 80% of their total mass for the first four hours of the experiment and the absolute number of larvae was 2.5 to 10 times greater than that in the two other media. The use of Erl's medium makes it possible to obtain a considerable number of Trichinella larvae in 4 to 6 hours of cultivation.
