susceptibility of legionella strains to the chlorinated biocide, monochloramine.members of the legionella genus find suitable conditions for their growth and survival in nuclear power plant cooling circuits. to limit the proliferation of legionella pathogenic bacteria in nuclear power plant cooling circuits, and ensure that levels remain below regulatory thresholds, monochloramine treatment can be used. although the treatment is highly effective, i.e. it reduces legionella numbers by over 99%, legionella bacteria can still be detected at low concentrations and rapid re-colo ...201324005820
development and evaluation of chlamylege, a new commercial test allowing simultaneous detection and identification of legionella, chlamydophila pneumoniae, and mycoplasma pneumoniae in clinical respiratory specimens by multiplex pcr.this study describes the development and evaluation of a new commercial test, chlamylege (argene inc.), which allows the simultaneous detection in respiratory samples of chlamydophila pneumoniae, mycoplasma pneumoniae, and most legionella species, as well as pcr inhibitors, by using a multiplex pcr and microplate hybridization. the sensitivities of chlamylege were 1 x 10(-3) ifu, 5 x 10(-2) color-changing units, and 1 cfu per reaction tube for c. pneumoniae, m. pneumoniae, and legionella pneumop ...200516000443
legionella confirmation using real-time pcr and syto9 is an alternative to current methodology.the currently accepted culture techniques for the detection of legionella spp. in water samples (as/nzs 3896:1998 and iso 11731 standard methods) are slow and laborious, requiring from 7 to 14 days for a result. we describe a fully validated rapid confirmation technique that uses real-time pcr incorporating the intercalating dye syto9 for the direct identification of primary cultures, significantly decreasing turnaround time and allowing faster remedial action to be taken by the industry.200516332896
low endotoxic potential of legionella pneumophila lipopolysaccharide due to failure of interaction with the monocyte lipopolysaccharide receptor cd14.legionella pneumophila, a gram-negative bacterium causing legionnaires' disease and pontiac fever, was shown to be highly reactive in in vitro gelation of limulus lysate but not able to induce fever and the local shwartzman reaction in rabbits and mice. we analyzed the capacity of purified l. pneumophila lipopolysaccharide (lps-lp) to induce activation of the human monocytic cell line mono mac 6, as revealed by secretion of proinflammatory cytokines and desensitization to subsequent lps stimulat ...19989712761
