Legionella is a bacterium that flourishes in pipes and tanks for potable water. And it may be found in all kinds of installations. Only its concentration is different. In only a few days the number of bacteria may grow to a distinctly hazardous level for the consumers of the installation. Maintenance, temperature and the structure of the installation may be crucial aspects for its growth.
The Legionella bacterium may cause the legionary disease, which is a serious form of pneumonia, often with a concomitant effect on other vital organs. The disease may cause death or invalidity. A quick doctor’s call is vital, as medicine against ordinary pneumonia has no effect.
