Résumé

The paper reports on hypothesis of calm down of plague natural foci activity and permanent factors influenced on it. Plague natural foci periodicity is natural phenomenon of carrier-rodents number and changing of their sensitiveness to the infectious deseases. Changing of the carrier- rodents sensitiveness depend on decreasing of the potential energy, iron balance in the blood and alteration adrenal hormone of the host animals. The authors suggests a hypothesis on host animals resistant depending on their body temperature and protein hereditary phenotype of the blood transferrin. At last, the authors have considered that should be the explanation of natural foci activity phenomenon make a valuable contribution. To study host’s body temperature and environment in comparison with their blood protein transferrin, haptoglobin, iron balance in blood and adrenal hormone (corticosteroids, cateholamines).
