Microbial content of drinking water in Finnish and Russian Karelia – implications for atopy prevalence.

There have been substantial differences found in prevalence of atopy in school children from Finnish and Russian Karelia. This study found that high microbial content in drinking water was inversely associated with atopy and a dose-response relationship was seen. The high microbial content of drinking water may be a surrogate marker for some other unidentified factors associated with poor living condition in Russian Karelia or it is possible that some direct immunomodulatory potential is exerted when the water is consumed. Natural waters may exposure individuals to environmental saprophytes which may play a crucial role in stimulating the innate immunity and the regulatory network involved in the development and maintenance of immunological homeostasis of the gut and respiratory tract mucosa.
