Helge: News about water shortage in Atlanta, Ga. Need to read more about it.

vermicon - solutions for microbiology: "Water is the most valuable resource on the planet. Yet the bacterial contamination of water can cause serious health problems. The reliability of VIT allows us to trust the water we use in our everyday lives.

One of the most dangerous pathogens in water are bacteria species belonging to the genus Legionella, and in particular L. pneumophila which causes Legionnaires' disease. This disease is a lung infection whereby 15% of all reported cases are fatal. In Germany more than 1500 people die every year due to infection with Legionella .

Legionella live in water habitats such as rivers, streams and lakes. The most dangerous threats for humans are showers, cooling towers and swimming pools, where Legionella enters the lungs when the aerosols are directly inhaled.

Once they are in the lungs they can cause pneumonia. Drinking contaminated water on the other hand is not so dangerous. Strong smokers however have an increased risk of infection as the process of preventing bacteria from entering the lungs through the respiratory tract is inhibited.

The incubation period of Legionella is 2 – 10 days. Thus if a contamination of water is quickly identified, counteractive measures can prevent a deadly course of disease. New studies have also shown that only about 85% of all infections are caused by L. pneumophila. "
