[The resistance of muscle larvae of Trichinella spiralis to exposure to low temperatures].

It has been shown that the resistance of muscular larvae of Trichinella spiralis to the effect of low temperatures depends on the conditions of freezing and composition of media possessing cryoprotective properties. It has been established that under optimal conditions (medium of microenvironment, conditions of freezing) during the storage in liquid nitrogen muscular larvae of T. spiralis preserve 50 to 60% of their resistance by the character of mobility and 11 to 15% by their capacity for reproduction. The question of creation of low-temperature bank for Trichinella is discussed.
