| [legionella in trondheim, norway--determining sources of contagion and tracing risk environments]. | legionnaires' disease, most often a serious condition, is a relatively rare disease in norway although in recent years it has been on the increase. because of clinical and microbiological diagnostic difficulties, one can assume that the number of new cases reported is significantly too low. | 2005 | 16012542 |
| alternative routes for dissemination of legionella pneumophila causing three outbreaks in norway. | three outbreaks of legionnaires' disease were reported in the fredrikstad/sarpsborg community, norway, in 2005 and 2008 caused by the l. pneumophila st15 and st462 strains determined by sequence based typing. in this retrospective study, we suggest that the aeration ponds, a part of the biological treatment plant at borregaard ind. ltd., are the main amplifiers and primary disseminators of the outbreak l. pneumophila strains. this result is supported by the finding that the st15 and st462 strain ... | 2010 | 20949911 |
| dispersion of legionella-containing aerosols from a biological treatment plant,norway. | legionella was detected in aeration ponds (biological treatment plant) at borregaard ind. ltd., norway, and in air samples harvested directly above these ponds. since 2005, three outbreaks of legionellosis occurred within a 10 km radius from this plant. this work addresses the dispersion patterns of legionella-containing particles by characterizing the aerosol plume emitted from these ponds (outbreak source) less than 500 meters using wind-tunnel measurements, cfd simulations, and real-life meas ... | 2011 | 21622136 |
