title: [Leptospira infection under the natural conditions of the environs of Saint Petersburg].
abstract: The existence of valent natural foci of leptospirosis, stable and polyhostal, under the conditions of urban agglomerations has been established. In an intensively urbanized landscape, the foci of mixed (natural and anthropic) type can be found. Depending on the character of microlandscape in a given zone, the main hosts of leptospires are different species of small mammals in whose populations, as a rule, the circulation of at least three Leptospira species is observed. Introduction of the 'carriership index' will help determine the role of different species of small mammals as the potential source of leptospires in the foci, as well as the proportion of different circulating Leptospira species and their zonal distribution.
