Introduction: Legionella Pneumophila bacteria is known as one of the most important nosocomial infections and the most common cause of death in patients. This study was aimed to identify Legionella Pneumophila bacteria in hospital water supply systems. Material and Methods: This descriptive cross-sectional study was performed to identify Legionella pneumophila in hot and cold-water systems of i...
متن کاملAn Investigation of the Legionella Pneumophila Infection in Pneumonic Patients in Three Different Infections Hospital Wards in Tehran
Legionella pneumophila is one of the causative agent of pneumonia in human being. In recent years many reports has been come from different parts of world regarding infectivity of this organism. This disease occurs almost because of contamination of air conditioning systems. For the purpose of assessment of the legionella pneumophila in pneumonic patients, 200 specimen from sputum and tracheo-b...
متن کاملEssential role for the Legionella pneumophila rep helicase homologue in intracellular infection of mammalian cells.
We have previously isolated 32 mutants of Legionella pneumophila that are defective in the infection of mammalian cells but not protozoa. The mutated loci have been designated macrophage-specific infectivity (mil) loci. In this study we characterized the mil mutant GK11. This mutant was incapable of growth within U937 macrophage-like cells and WI-26 alveolar epithelial cells. This defect in int...
متن کاملUltrastructure of Legionella pneumophila.
Eleven lung samples positive for Legionnaires' disease, 12 strains of Legionella pneumophila cultured on various bacteriological media, and one strain growth in the yolk sac of fertile hens' eggs were examined by negative staining, thin sectioning, and scanning electron microscopy. All organisms studied were ultrastructurally similar irrespective of strain, source, or method of cultivation, pre...
متن کاملLegionella pneumophila pathogenesis in the Galleria mellonella infection model.
Legionella pneumophila is a facultative intracellular human pathogen and the etiological agent of severe pneumonia known as Legionnaires' disease. Its virulence depends on protein secretion systems, in particular, the Dot/Icm type IV secretion system (T4SS), which is essential to establish a replication-permissive vacuole in macrophages. The analysis of the role of these systems and their subst...
