The high rate of isolation of this strain from both clinical and environmental samples makes identification of the source of infection difficult during epidemiological investigations. The full-length genome sequence of this strain was recently determined, and it revealed the presence of a CRISPR\/\n            <jats:italic>cas<\/jats:italic>\n            complex. The aim of this study was to develop and evaluate a spoligotyping tool based on the diversity of this CRISPR locus that would allow the accurate subtyping of the\n            <jats:named-content content-type=\"genus-species\">L. pneumophila<\/jats:named-content>\n            serogroup 1 ST1\/Paris pulsotype.

A total of 46 different spoligotypes were detected, and 41 of these were specifically identified in the ST1\/Paris pulsotype isolates. In 27 of 33 epidemiological investigations, the environmental source of contamination was confirmed by comparing spoligotypes of clinical isolates with those of environmental isolates. With an index of discrimination of 79.72% (95% confidence interval, 75.82 to 83.63), spoligotyping of the\n            <jats:named-content content-type=\"genus-species\">L.
