in Journal of clinical microbiology [J Clin Microbiol] > Vol. 50, N° 5 (Mai 2012) . - 1725-6Mots-clés : Legionella ; Culture microorganisme ; Microbiologie ; Test ; Légionellose ; France Résumé : We evaluated the contribution of amoebic coculture to the recovery of Legionella from 379 respiratory samples. The sensitivity of axenic culture was 42,1%. The combination of axenic culture with amoebic coculture increased the isolation rate of Legionella to 47,1%. Amoebic coculture was particularly efficient in isolating Legionella from respiratory samples contaminated by oropharyngeal flora. (R.A.)

Here, we investigated possible host factors associated with susceptibility to community-acquired Legionnaires disease caused by the endemic Paris and Lorraine strains. METHODS: We conducted a double-nested exploratory case-control study with use of data from the French national surveillance network of incident Legionnaires disease cases notified from 1998 through 2007. Patients with community-acquired Legionnaires disease and an L. pneumophila serogroup 1 isolate were eligible. Case patients were patients infected by the Paris or Lorraine strain, and control patients were those infected by sporadic strains. Epidemiological and clinical factors associated with infection with the Paris and Lorraine strains were assessed by calculating adjusted odds ratios (aOR) in multivariate logistic regression models. RESULTS: We studied 1090 patients infected by sporadic strains (n = 920), the Paris strain (n = 80), or the Lorraine strain (n = 90). Infection with the Paris strain was significantly associated with female sex (aOR, 1.98; 95% confidence interval [CI], 1.19-3.28), steroid therapy (aOR, 3.16; 95% CI, 1.76-5.68), and a history of cancer or hematologic malignancies (aOR, 2.08; 95% CI, 1.15-3.76). In addition, the mortality rate was higher among patients infected with the Paris strain than in the control group (38% vs. 25.5%). The Lorraine strain was associated with smoking (aOR, 1.82; 95% CI, 1.14-2.91) and reduced mortality (9.9%). CONCLUSION: Several host characteristics were associated with the risk of infection by endemic strains of L. pneumophila serogroup 1. These findings may help to guide preventive measures. Factors predisposing patients to infection by specific strains need to be explored further. (R.A.)

in Emerging infectious diseases [Emerg Infect Dis] > Vol. 14, N° 4 (2008) . - 673-5Mots-clés : Légionellose ; Epidémie ; Prévalence ; Lorraine ; Paris ; France Résumé : Legionellosis is a pneumonia caused by inhalation of Legionella spp. in aerosol water particles. Legionella pneumophila is responsible for approximately 90% of cases; serogroup 1 alone accounts for approximately 85% of cases. Epidemiologic analyses based on pulsed-field gel electrophoresis (PFGE) and sequence-based typing of clinical isolates of L. pneumophila serogroup 1 have detected sporadic, epidemic, and endemic strains. Most cases are sporadic and are associated with strains that have not been identified. A strain is considered endemic to an area when several isolates that have identical PFGE patterns and that cause several epidemiologically unrelated cases of legionellosis are detected in that area. Since 1998, the most prevalent strain endemic to France has been the Paris strain, which was responsible for 12.2% of culture-confirmed cases of legionellosis from 1998 through 2002. The Paris strain has also been detected in clinical samples from several other European countries.
