Role of mouse-like rodents in circulation of causative agents of natural and focal diseases of the Republic of Mordovia

The assessment of a role of mouse-like rodents in epizootic activity of the natural centers of a tulyaremia, leptospirosis, an yersiniosis, hemorrhagic fever with a kidney syndrome in Mordovia in recent years was the purpose of this work. For the characteristic of activity of an epizooty in populations of small mammals materials of long-term catching with the subsequent analysis of the caught small animals on contamination are used. It is shown that of the Republic of Mordovia most often mouse-like rodents are carriers of a tularemia and hemorrhagic fever with the kidney syndrome. During researches the greatest number of the registered cases of a carriage of a tularemia and hemorrhagic fever with the kidney syndrome mouse-like rodents is noted in 2009, 2010 and 2015. Among different types of the small mammals infected with a tularemia the greatest number it is noted for the red vole (42%), a small forest mouse (25%) and a house mouse (15%). Among different types of the small mammals infected hemorrhagic fever with the kidney syndrome the greatest number is noted for a house mouse (41%), the red vole (23%) and the ordinary vole (23%). In structure of the population of the small rodents infected with leptospirosis on ordinary the vole is necessary 52%, a field mouse - 34%, a house mouse - 14%. Positive correlation of dynamics of incidence of the population of the republic from the number of mouse-like rodents is revealed, especially it is accurately traced for hemorrhagic fever with the kidney syndrome and leptospirosis.
