In 2003, ionization became the first such hospital disinfection process to have fulfilled a proposed four-step modality evaluation; by then it had been adopted by over 100 hospitals.
Legionella pneumophila, the primary causative agent for Legionnaire's disease, is an aerobic, pleomorphic, flagellated, non-spore-forming, Gram-negative bacterium. [1] [2] L. pneumophila is a intracellular parasite that preferentially infects soil amoebae and freshwater protozoa for replication.
Legionella is often present in small quantities in the water cruise lines pick up in port for drinking, use in showers and amenities like whirlpool spas, but not high enough to make people sick ...
