Abstract:

In this chapter, the authors report on an epidemiological study on the immune responses of residents in homes with heavy and with minor contaminations in their hot water systems. In one of the two residential areas with a central hot water system, contamination of up to 1 million CFU/liter had been known for several years. In the other residential area, decentralized hot water systems were installed in all houses so that no problem would be assumed. Using the criterion of antibody titer of 1:128 (immunofluorescence), 1.9% of the exposed and 1.1% of the control persons exhibited positive antibody titers against serogroups 1 to 14, and 7.5% of the exposed and 6.5% of the control persons had positive antibody titers against species in total. In Eberswalde, a small city near Berlin, the prevalences of positive antibody titers in 246 healthy inhabitants were 10.2% in the exposed group and 13.4% in the control group. In the authors' investigation the participants exposed to heavy contamination in their hot water systems at home had higher antibody titers against than participants living in the control area.
