Legionella is a genus of gram-negative bacteria that can be seen using a silver stain or grown in a special media that contains cysteine, an amino acid.It is known to cause legionellosis [3] (all illnesses caused by Legionella) including a pneumonia-type illness called Legionnaires' disease and a mild flu-like illness called Pontiac fever. [3]
There is a relatively high abundance genes encoding eukaryotic-like proteins (ELPs). ELPs are beneficial for mimicking the bacteria' eukaryotic hosts for pathogenicity. Other genes of L. pneumophila encode for Legionella-specific vacuoles, efflux transporters, ankyrin-repeat proteins, and many other virulence related characteristics. [29]
F-box proteins are involved in the ubiquitination of proteins targeted for degradation by the proteasome. AnkB F-box is a protein that assembles host cell polyubiquitinated proteins on the cytoplasmatic side of Legionella containing vacuole (LCV). [1] This effector is required for intracellular proliferation within human and amoeba cells and ...
Members of the order Legionellales can be molecularly distinguished from other Gammaproteobacteria by the presence of four conserved signature indels (CSIs) in the proteins tRNA-guanine(34) transglycosylase, lipoprotein-releasing system transmembrane protein lolE and tRNA (guanosine(37)-N1)-methyltransferase TrmD.
L. jordanis was found to contain the gene loci sidH, sidE, sidB, and sidG which express a Dot/Icm effector protein. [13] This effector protein is essential for L. pneumophila to infiltrate host cells, so it is thought to be used as a virulence factor in L. jordanis, also. [13] Both strains of L. jordanis tested positive for proteolysis and ...
The legionella bacteria responsible for the disease lives and multiplies in water areas like hot tubs, air conditioners, mist sprayers in grocery store produce departments, and water systems.
Man-made water sources “become a health problem when small droplets of water that contain the bacteria get into the air and people breathe them in,” the CDC said in a fact-sheet. The majority ...
Legionella is a common bacteria found in the environment and in water systems. It can cause a severe type of pneumonia - Legionnaires' disease - which impacts lungs, or a mild flu-like illness ...
