Legionella

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).…

different harmful bacteria such as Legionella pneumophila. Macrophages ingest these bacteria in order to digest them, however, the Legionella pneumophila containing phagosomes (LCPs) avoid the lysosomes of the cell by replicating and converting the phagosome into an endoplasmic reticulum derived organelle with the aid of Sar1 and ADP-ribosylation (ARF). Sar1 and ARF are GTPases that control the production of the vesicles COPII- and COPI-. From there the bacterium attracts the host vesicles to…

Introduction With patient safety being at the forefront of hospitals’ priority, it’s imperative for administration to implement infection control protocols. The practice of preventive measures along with staff education is necessary in the reduction of hospital liability, extended inpatient stays and loss in revenue. Although some strategies are standard throughout hospital organizations, data and con-stant monitoring of these procedures will provide insight into compliant areas or those that…

1. The organism that is the cause of this patient’s illness is Legionella pneumpohila, which means the patient has Legionnaire’s disease. Although there are other organisms that can cause similar diseases, it is clear that Legionella pneumpohila is the organism responsible for this patient’s disease. There are several reasons, but the one that stands out the most is that this organism can only grow on buffered charcoal-yeast extract, which is why there was no growth present on the 5% sheep blood…

Legionnaires’ Disease is a disease caused by Legionella bacteria, and is named after a convention held in Philadelphia in which members of the American Legion attended and contracted the illness. Legionella bacteria are found naturally in fresh bodies of water, and grow in warm water. People can be exposed to the bacteria from not-properly disinfected hot tubs, air-conditioning units in large buildings, fountains, or swimming in warm bodies of water and inhaling small amounts of said water. The…

Introduction Legionnaires’ Disease is a kind of common pneumonia and caused by bacteria, Legionella Pneumophila. Legionnaires’ Disease becomes more and more in recent years in Hong Kong. Background information The first outbreak of Legionnaires’ Disease happened in 1976 which found in Philadelphia in the United States and caused 34 people to die. It is an acute bacterial disease, its incubation period is 2-10 days. Thus, the most common transmission of Legionella are disseminate sprays and…

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…

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…

His body temperature was 100 degrees F, heart rate 78 beats per minute, and his blood pressure was 96/50 mm Hg. He was weaned of off 50% oxygen through a face mask to a 2 liters of oxygen by a nasal cannula. His electrolyte levels were unremarkable, but his white blood cell count increased to 26.0 x 109/L. The cultures for influenza A and B viruses were negative as well as the blood cultures for bacteria and fungus. The urine test for Legionella antigen was positive. The infectious disease team…
