The leptospirosis together with other natural-focus infections are of great problem of public health of Russian Federation. For the most of natural-focus infections are characterized the dispersion in the zones of moderate climate. To such zones are refered the lands along the Volga, where variety of landscapes , weather-climatic factor, the speciality of geobotanic assotiations and faunistic complexes contribute to supporting of stimulants of leptospirosis. The changes in Russia in the period of the last decades, the difficult transitional period to the news forms of social and economic relations, no doubts create the new row of conditions complicating the situation. The forming new social-economic reasons give the significant role of the appearance of leptospirosis on the territory of Ulianovsk region. The innovation to approach to the epidemiological supervision of leptospirosis in the present time should consider the formation of new natural sources under the action of new anthropogenic and climatic factors; change of biocenotic structure of natural sources; forming of natural-focus of combined infection diseases (leptospirosis and GLPS); change of epidemic potentiality of natural sources; sinantropization of infection diseases.

Key words: leptospirosis, natural focal infection, anthropogenic and climatic factors, epidemic potential.

Long-term materials on the occurrence dynamics have been reviewed for cellar mosquito Culex pipiens pipiens f. molestus and cat flea Ctenocephalides felis in Irkutsk city facilities. The materials show that within the period from 1997 till 2007 the occurrence and abundance of mosquitos in cellars declined. Though the number of places characterized by flea populations has not changed a lot since 2002. A conclusion was drawn that common disinsecting measures are not enough to control these two types of blood-sucking insects. Disinsecting measures should be undertaken simultaneously with a number of actions including drainage of cellars and ensuring their inaccessibility to domestic animals who may be potential feeders of fleas imago. In addition, it is very likely that the flea population became resistant to widely used insecticides. In order to ensure efficiency of the disinsecting measures it is essential to replace the applied poisons and to regularly change the insecticides in future.

Key words: synathropic blood-sucking insects, disinsection, mosquitos, fleas, sanitary actions.

The article contains the theoretical problems of disinfectology. Authors discussed disinfection, disinsection and deratization (rodent control), as a independent brunches of epidemiology with different objects and points of action (different links of epidemical process), aims, tasks, objects of investigation, methods of action to the biological objects.

Key words: disinfection, disinsection, deratization, disinfectology, epidemiology, epidemical process, science, object, aims, tasks, methods.
