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]
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 ...
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 spp. enter the lungs either by aspiration of contaminated water or inhalation of aerosolized contaminated water or soil. In the lung, the bacteria are consumed by macrophages, a type of white blood cell, inside of which the Legionella bacteria multiply, causing the death of the macrophage. Once the macrophage dies, the bacteria are ...
Once pathogens attach to host cells, they can cause direct damage as the pathogens use the host cell for nutrients and produce waste products. [23] For example, Streptococcus mutans, a component of dental plaque, metabolizes dietary sugar and produces acid as a waste product. The acid decalcifies the tooth surface to cause dental caries. [24]
Legionella micdadei is a Gram-negative bacterium from the genus Legionella, which stains acid-fast. It stains weakly, but loses this trait upon being grown in culture. Tatlockia micdadei is an alternative term for L. micdadei, the Pittsburgh pneumonia agent and TATLOCK strain. [2] It is named after Joseph E. McDade, who first isolated L ...
The United Stated Department of Agriculture on Wednesday, June 21 permitted two California firms to sell the products, known as The post EXPLAINER: Chicken made from cells in a lab; what it is and ...
Lactoferrin is one of the transferrin proteins that transfer iron to the cells and control the level of free iron in the blood and external secretions. It is present in the milk of humans and other mammals, [ 13 ] in the blood plasma and neutrophils and is one of the major proteins of virtually all exocrine secretions of mammals, such as saliva ...
