Legionellosis

Legionnaires' disease is known as a " Gram-negative bacteria". This means that during a Gram staining test the Legionella doesn't keep the pink dye. The reasoning behind this is because of the "cell wall composed of a thin layer of [peptidoglycan]" (Medicinenet.com). A counter stain is later added to make sure the bacteria being tested is surely Gram-negative. Legionnaires' disease is caused by the Legionella bacteria. In order to acquire the disease you must first obtain the Legionella bacteria. The spread of the bacteria can be "from inhaling airborne water droplets or mist containing viable Legionella pneumophila" (Legionellosis Guideline: Best Practices for Control of Legionella 3). Another important fact to note is that the "bacteria are NOT spread from one person to another person" (CDC.gov). Because Legionella is a bacteria, it commonly grows in warm water. Transmission of the bacteria can be from multiple places such as, water cooling systems, humidifiers, hot tubes, and hot water tanks. A large percentage of infections "occur in middle-age or older people" and "children can get the infection" although it isn't as bad (nlm.nih.gov). Most adults "do not become ill" (CDC.gov).…

Legionnaires’ Disease Suzanne Kery HIT 112-Laboratory and Diagnostic Tests Professor: Kathy Taylor June 8, 2016 Legionnaires’ Disease Legionnaires’ disease is a type of pneumonia caused by a gram-negative bacteria, Legionella pneumophila (VanMeter and Hubert, p.286). This bacteria can be found almost anywhere; however, this microbe thrives in warm, moist environments, such as pools, spas, hot tubs and air conditioning units. Legionnaires’ disease is transferred through the inhalation…

Introduction This assignment explores several online sources that contain materials on the impact of Legionaries’ Disease to public health and its association with the role of a Public Health Inspector/Environmental Health Officer. Legionaries’ Disease is caused by roughly 35 Legionella bacteria species, with symptoms of severe pneumonia and psychological changes. (Canadian Centre for Occupational Health and Safety, 2015) With an increase of the elderly population in North America and the use…

INTRODUCTION Two significantly important highly pathogenic infection diseases namely Legionellosis and Influenza remains even today a threat to global health. They can cause severe community-acquired pneumonia with respiratory failure but they can also generate hospital-acquired infections.1 Moreover Legionella infection could attribute to influenza infection. The cause of influenza was definitively resolved back in 1930s with the isolation of swine influenza; a virus which when administered…

to the method is to gather information about the problem so that you can develop an experiment or an hypothesis. In the article by authors David W. Fraser and Joseph E. McDade, they lay out these four steps. The first step to the method as listed above is to understand the problem and state it clearly. The problem proposed in the article “Legionellosis,” was that there was an…

City is in full compliance with the Federal Safe Drinking Water Act, this information is being shared as part of a public awareness campaign to ensure that everyone takes note that no level of lead is considered safe," (Merrit). After much publicity and many news stories, the source water for the City of Flint was switched back to treated Lake Huron water supplied by the Detroit Water and Sewage Department, in October of 2015.
