In the water supply of a hospital in northern Portugal.

The Legionella sp. (aerobic gram-negative bacilli) are widely distributed in aquatic environments, but it is in artificial environments that they hit higher levels due the characteristics propitious (like temperature, pH and biofilms presence) to their development. Human intervention was crucial for the presence of Legionella that has become common in building networks of water supply, cooling towers, air conditioning systems, swimming pools, tanks, humidifiers, condensers, ornamental fountains, among others.engLegionellaArtificial environmentsconference object
