title: [Identification of Legionella spp. by means of cultural and molecular methods in a public hospital].
abstract: An epidemiologic study on the isolation of Legionella spp from the sanitary water of a public Hospital in Cagliari (Italy) has been performed. The aim of the study was the comparison between the isolation of various Legionella spp from different hospital sources and the real hazard of Legionella infection of the inpatients. Two test methods were used for Legionella detection: a) the culture on selective media, that has the disadvantage of being quite time-consuming and of isolating also other bacterial species. Furthermore, the culture method often fails the isolation of vital but not culturable bacteria (VBNC); b) the PCR molecular method, which is rapid and precise and recognizes also VBNC cells. The most relevant result of this work was that, in spite of the isolation of a considerable number of Legionella spp (even Legionella pneumophila), no case of infection was detected in the Hospital during the period of the study.
