Retrospective epidemiological review on L. pneumophyla

Abstract

During the first annual control on hospital infections, was observed a curious but explainable trend regarding evidence of Legionella pneumophyla isolated by water systems in numerous public and private nosocomial structures. After first massive isolation of L. pneumophyla strains at the beginning, a considerable reduction of isolates was noted, due to a program based on control and surveillance of water supplies, with regards to the aspectatives. But, in these last years a recurrent presence of isolates of L. pneumophyla was noted, despite all procedures used for the control of these bacteria.
