title: [Temperature dependence of the arginase activity of the plerocercoids of Triaenophorus nodulosus and Diphyllobothrium latum].
abstract: The effect of temperature on the arginase enzyme activity in Triaenophorus nodulosus and Diphyllobothrium latum was studied. The temperature optimum of arginase of T. nodulosus (definitive hosts are fishes) is at 27 degrees while in D. latum it is at 57 degrees. It has been inferred that a certain preadaptation of some enzyme properties (temperature optimum, thermostabolity) to a temperature regime of a definitive host takes place. Biochemical mechanisms of preadaptation of enzyme systems of helminths to temperature are discussed.
