Une étude du pouvoir bactéricide de l’argent s’est intéressée à la résistance de trois bactéries : L’utilisation d’ionisateur de cuivre/argent requiert lors de son utilisation sur des grandes installations de multiplier les équipements, ce qui engendre un coût prohibitifLes oxydants sont les produits de désinfections les plus couramment utilisésLa température améliore sensiblement l’efficacité du chlore contre les Légionelles. Des essais sur des Facteurs de multiplication, de survie et de virulenceDétruire les Légionelles sur le point de consommation de l’eauFacteurs de multiplication, de survie et de virulenceDétruire les Légionelles sur le point de consommation de l’eauLa présence d’anticorps chez les usagers d’une installationLa sous-estimation de l’impact des Légionelles est également évidente au niveau du diagnostic de la maladieMorton, L.H.G., Greenway, D.L.A., Gaylarde, C.C. 1-41.Donlan, R, et al.

Ce sont des bactéries naturellement présentes dans leau et dans les boues, responsables d'une maladie respiratoire, la légionellose. On observe une nette diminution des colonisations par les Légionelles.

E. & Goldman, A. Y.T. 2019 Jun;27(6):550-561. doi: 10.1016/j.tim.2018.12.012. The most important host defense mechanism against invading intracellular opportunistic bacteria is phagocytosis by macrophages, followed by intracellular killing and digestion of the microbes. The facultative intracellular bacterium Legionella pneumophila parasitizes protozoa in aquatic environments and alveolar macrophages in susceptible human hosts. We determined both the MICs and intracellular efficacy of moxifloxacin, trovafloxacin, clinafloxacin and levofloxacin in the Mono Mac 6 infection model. SLC1A5 (hATB(0,+)), a neutral amino acid transporter, was upregulated in the host cells after infection with L. pneumophila. Residence within a membrane-bound organelle is a survival strategy common to intracellular bacterial pathogens [1–3].Legionella pneumophila, the etiological agent of a severe pneumonia known as Legionnaires’ disease, can establish a unique endoplasmic reticulum (ER)-derived vacuole in amoebae and also in mammalian macrophages [4–8].

In order to study the mechanisms involved in intracellular survival of Legionella a genomic library of strain Legionella pneumophila Philadelphia I was established in Escherichia coli K-12.

Name must be less than 100 characters Once in the lung, L. pneumophila infects and multiplies in alveolar macrophages. During intracellular replication, Legionella has a biphasic developmental cycle that alternates between a replicative and a transmissive form. Cela oblige à toujours prendre en compte les réactions complexes que les composés dissous dans l’eau à traiter peuvent engendrerL’utilisation des Chloramines pour la désinfection de l’eau potable n’est pas autorisée en Europe.
