GETEROTERMNY ANIMALS (grech, heteros of other, another + thermos warm) — the gomoyotermny (hematothermal) animals changing body temperature in certain functional states at preservation of ability to support its new level with the help fiziol, mechanisms of thermal control. Usually. reduce body temperature during dormant periods — a dream (a humming-bird, bats) or seasonal hibernations (see), but some (small rodents, insectivorous, etc.) in extreme conditions are capable to lower body temperature and in an active state. In such way of. have an opportunity more economically to use reserve stocks of an organism during those periods when their recovery is impossible, keeping ability to control body temperature with the help fiziol, mechanisms (see. Thermal control ). Change of body temperature affects infectious processes in an organism of. E.g., the groundhogs and gophers infected in a condition of hibernation or shortly before it with plague do not get sick (clinically), but keep the activator which breeds in an organism only after its transition to a gomoyotermny (hematothermal) state. After awakening from hibernation the generalized infection which is coming to an end with death of an animal usually develops. Thus, the causative agent of plague can remain in an organism of a rodent from one epizootic season to another.
