The surveillance of Legionnaires' disease (LD) in Europe is carried out by the European Legionnaires' Disease Surveillance Network (ELDSNet) and coordinated by the European Centre for Disease Prevention and Control (ECDC). All cases reported in 2009 and 2010 and meeting the European case definition were electronically transmitted to The European Surveillance System (TESSy) database. A total of ...

Counterimmunoelectrophoresis (CIE) was found to be a rapid, specific method for detecting circulating antibodies to Legionella pneumophila, the aetiologic agent of Legionnaires' disease in human sera. Optimum conditions for performing the test are given. Better precipitin lines are observed when the gel support is neutral, and a result may be obtained in 90 to 180 minutes. Comparison of results...

BACKGROUND To stop a possible outbreak of Legionnaires' disease (LD) at an early stage an outbreak detection programme was installed in The Netherlands. METHODS The programme consisted of sampling and controlling of potential sources to which LD patients had been exposed during their incubation period. Potential sources were considered to be true sources of infection if two or more LD patient...

We evaluated the effectiveness and safety of rifampicin addition to clarithromycin in the treatment of Legionnaires' disease. An observational cohort study was conducted on patients assigned to a Legionnaires' disease outbreak. Of 32 patients with confirmed Legionella pneumonia, 11 received clarithromycin monotherapy and 21 received combination therapy of clarithromycin with rifampicin. Both gr...

Monochloramine disinfection of municipal water supplies is associated with decreased risk for Legionnaires' disease. We conducted a 2-year, prospective, environmental study to evaluate whether converting from chlorine to monochloramine for water disinfection would decrease Legionella colonization of hot water systems. Water and biofilm samples from 53 buildings were collected for Legionella cul...

Fourteen cases of Legionnaires’ disease were confirmed in residents from England and Wales with history of travel to Corfu, Greece, in the 14 days before symptom onset. These cases were reported to the Health Protection Agency national surveillance scheme for Legionnaires’ disease in residents of England and Wales between August and October 2011. In addition, one case in a Greek national and a ...

A strain of the Legionnaires disease bacterium (LDB) that was isolated by Joseph E. McDade from a postmortem lung specimen of a patient with fatal atypical pneumonia at the Veterans Administration Hospital in Togus, Maine was serologically different from 16 other strains of LDB that had been isolated previously from patients in other geographic locations. The serological differences of the Togu...

Legionella pneumophila has frequently been isolated from patients with Legionnaires disease and in several instances also from epidemic-related environmental samples. A selective medium was developed and used successfully to isolate Legionella pneumophila and Legionella-like organisms from environmental specimens animal inoculation methods. Legionella pneumophila is a Gram-negative, facultative...

During the summer of 2015, New York, New York, USA, had one of the largest and deadliest outbreaks of Legionnaires' disease in the history of the United States. A total of 138 cases and 16 deaths were linked to a single cooling tower in the South Bronx. Analysis of environmental samples and clinical isolates showed that sporadic cases of legionellosis before, during, and after the outbreak coul...
