Susceptibility of Legionella pneumophila to ultraviolet radiation.
Distilled water suspensions of Legionella pneumophila were found to be sensitive to low doses of germicidal ultraviolet radiation.
متن کاملIdentification of macrophage-specific infectivity loci (mil) of Legionella pneumophila that are not required for infectivity of protozoa.
We have recently shown that many mutants of Legionella pneumophila exhibit similar defective phenotypes within both U937 human-derived macrophages and the protozoan host Acanthamoeba (L.-Y. Gao, O. S. Harb, and Y. Abu Kwaik, Infect. Immun. 65:4738-4746, 1997). These observations have suggested that many of the mechanisms utilized by L. pneumophila to parasitize mammalian and protozoan cells are...
متن کاملInvestigation of Legionella Pneumophila bacteria in hospital water supply systems
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 کاملActivity of iclaprim against Legionella pneumophila.
larities. A comparison between the TPqnrS-1a-associated QnrS1 protein and the 218-amino-acid proteins from Vibrio splendidus (accession no. EAP95542) and Vibrio spp. (accession no. EAQ55748)—the latter two considered as a natural reservoir of qnrS genes—revealed 83% and 82% amino acid identity, respectively, and 91% amino acid similarity. Previous studies revealed that the qnrS1 gene is often l...
متن کاملThe Legionella pneumophila PilT homologue DotB exhibits ATPase activity that is critical for intracellular growth.
The ability of Legionella pneumophila to grow and cause disease in the host is completely dependent on a type IV secretion system known as the Dot/Icm complex. This membrane-spanning apparatus translocates effector molecules into host cells in a process that is poorly understood but that is known to require the putative ATPase DotB. One possible role for DotB is suggested by its similarity to t...
