Interrelationships between parasites and their hosts. IV. Cytochrome c oxidase thermal-acclimation patterns in à larval trematode and its host.

摘要: Abstract Cytochrome c oxidase activity has been determined at different temperatures (10, 15, 20, 25, 30, 35, 40 °C) for sporocysts of Zoogonus lasius , digestive gland tissue from its host Nassarius obsoleta which was infected with Z. and the uninfected N. . Preparations cold- (10 warm-acclimated (25 snails were utilized. Q 10 Patterns differentially distinctive sporocysts, noninfected tissues. Enzymatic lower each assay temperature than that tissues, pattern acclimation unlike either or tissue. The level in significantly greater intermediate to higher snails. Following cold-acclimation, noninfective Thus, thermal-acclimation cytochrome gland, as well rate activity, is clearly altered parasitism.
