Legionella pneumophila serogroup 1 strain Paris: endemic distribution throughout France.
نویسندگان
چکیده
An analysis of 691 French clinical Legionella isolates showed that the endemic L. pneumophila serogroup 1 strain Paris was responsible for 12.2% of all cases of legionellosis and had a specific pulsed-field gel electrophoresis pattern. We also demonstrated the presence of this endemic clone throughout Europe.

Legionella pneumophila sequence type 1/Paris pulsotype subtyping by spoligotyping.
Endemic strains of Legionella pneumophila sequence type 1 (ST1), in particular the ST1/Paris pulsotype, are dispersed worldwide and represent about 10% of culture-proven clinical cases of Legionnaires' disease in France. The high rate of isolation of this strain from both clinical and environmental samples makes identification of the source of infection difficult during epidemiological investig...
متن کاملMolecular typing of nosocomial isolates of Legionella pneumophila serogroup 3.
In Paris, France, an outbreak of pneumonia due to Legionella pneumophila serogroup 3 was observed in Necker (four cases) and Pitié (six cases) hospitals. Neither the 10 clinical isolates nor 5 tap water isolates from Necker Hospital harbored plasmids. Clinical and environmental serogroup 3 isolates and serogroup 3 reference strain Bloomington 2 were analyzed by chromosomal probe fingerprinting....
متن کاملClinical and environmental distributions of Legionella strains in France are different.
In France, the clinical distribution of Legionella species and serogroups does not correspond to their environmental distribution. Legionella pneumophila serogroup 1 is more prevalent among clinical isolates (95.4%) than in the environment (28.2%), whereas L. anisa is more frequent in the environment (13.8%) than in the clinical setting (0.8%).
متن کاملAntibiotic susceptibilities of Legionella pneumophila strain Paris in THP-1 cells as determined by real-time PCR assay.
OBJECTIVES Legionella species are facultative intracellular bacteria. Evaluation of the activity of antibiotics against intracellular L. pneumophila is more predictive of their in vivo efficacy than MICs as determined in axenic medium. However, current methodologies are based on cfu count determination, and are tedious because of the slow growth of Legionella spp. We investigated antibiotic sus...

Legionella pneumophila, the causative agent of Legionnaires’ disease, replicates as an intracellular parasite of amoebae and persists in the environment as a free-living microbe. Here we have analyzed the complete genome sequences of L. pneumophila Paris (3,503,610 bp, 3,077 genes), an endemic strain that is predominant in France, and Lens (3,345,687 bp, 2,932 genes), an epidemic strain respons...
