Legionella: From Protozoa to Humans
Pathogens that are able to enter and multiply within human cells are responsible for multiple diseases and millions of deaths worldwide. Thus, the challenge is to elucidate these pathogen-specific and cell biological mechanisms involved in intracellular growth and spread. Bacteria from the genus Legionella belong to this group of pathogens. They are environmental bacteria and ubiquitous in natu...
متن کاملLegionella effectors that promote nonlytic release from protozoa.
Legionella pneumophila, the bacterial agent of legionnaires' disease, replicates intracellularly within a specialized vacuole of mammalian and protozoan host cells. Little is known about the specialized vacuole except that the Icm/Dot type IV secretion system is essential for its formation and maintenance. The Legionella genome database contains two open reading frames encoding polypeptides (Le...
متن کاملComparison of disinfectants for biofilm, protozoa and Legionella control.
The aim of this study was to compare the efficiency of different disinfectants applicable to Legionella control in domestic water systems. A domestic water supply simulation unit that allowed simulation of real-world conditions was developed for this purpose. The system, consisting of seven identical rigs, was used to compare treatment efficiency under equivalent conditions of system design, ma...
متن کاملSecond serogroup of Legionella feeleii strains isolated from humans.
Three strains of Legionella feeleii from patients with pneumonia (425-MI-H, 691-WI-H, and 693-WI-H) and one environmental strain (713-MI-E) received at the Centers for Disease Control for reference diagnostic testing were compared with the type strain WO-44C-C3 (ATCC 35072) by DNA hybridization, chemical analysis of cellular fatty acids and ubiquinones, biochemical tests, and serological charac...
متن کاملImmunity to Protozoa
Parasites with complex life cycles often stimulate both antibodyand cell-mediated defence mechanisms, whose effectiveness depends on the particular parasite and the stage of infection. Malaria, which is caused by different species of plasmodia, ranks amongst the most common and important parasitic diseases. Infection of humans is initiatedby thebite of an infectedmosquito, resulting in the inje...
