Five samples collected from 17 initially suspected cooling towers at the Port of Ghent near Evergem, tested positive for Legionella pneumophila, 3 with average and 2 in high quantities. [68] [72] Genetic testing confirmed 1 of 2 towers with high quantities to have links with the patients. [73] Swedish-Finnish Stora Enso admitted to be ...
Buffered charcoal yeast extract (BCYE) agar is a selective growth medium used to culture or grow certain types of bacteria, particularly the Gram-negative species Legionella pneumophila. [1] It has also been used for the laboratory diagnosis of Acanthamoeba keratitis , [ 2 ] Francisella and Nocardia spp .
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 ...
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.

The dip slide test consists of a sterile culture medium on a plastic carrier that is dipped into the liquid to be sampled. [3] The culture is then incubated, allowing for microbial growth. [ 2 ] Most Dip slides consist of 1 - 2 agars attached to a flexible plastic paddle, this allows full contact of the agar onto the desired area for testing. [ 4 ]
Ionization can be an effective process to control Legionella in potable water distribution systems found in health facilities, hotels, nursing homes, and large buildings. . In 2003, ionization became the first such hospital disinfection process to have fulfilled a proposed four-step modality evaluation; by then it had been adopted by over 100 hospitals.
During the 1960s and 1970s in the United States, a growing concern for environmental issues and health impacts of chemicals prompted increased federal regulation, particularly in the chemical and pharmaceutical sectors, leading to more stringent product testing requirements and the development of inspection programs targeting laboratories ...
