Summary. Pneumonia is a respiratory infection characterized by inflammation of the alveolar space and/or the interstitial tissue of the lungs.In industrialized nations, it is the leading infectious cause of death.Pneumonia is most commonly transmitted via aspiration of airborne pathogens (primarily bacteria, but also viruses and fungi) but may also result from the aspiration of stomach contents Overview of classic presentation and illness script for Legionnaire's Disease.Please like and subscribe if you like this video as I plan to regularly upload.

It usually affects older males and is more severe in smokers, alcoholics, diabetics and immunosuppressed patients An acute, sometimes fatal, pneumonia-like bacterial infection characterized by high fever, malaise, muscle aches, respiratory disorders and headache. It is named for an outbreak at the 1976 philadelphia convention of the american legion. Legionnaires' disease is a type of pneumonia caused by bacteria Culture on BCYE is the specific clue that the organism is Legionella pneumophila. The disease is respiratory Legionellosis, also known as Legionnaires disease, because the disease was first described when it occurred in epidemic form following an American Legion convention at a Philadelphia hotel Legionella is a facultative intracellular, gram-negative bacilli. Legionella does not grow on common culture media because it requires certain supplementation (cysteine and iron). Legionella can be isolated on a buffered charcoal yeast extract (BCYE) medium

Start studying USMLE Step 1 Mnemonics-Microbiology (Bacteria). Learn vocabulary, terms, and more with flashcards, games, and other study tools Legionnaires' disease describes infections caused by the Legionellaceae family. The Legionella bacterium is a small, aerobic, waterborne, gram-negative, unencapsulated bacillus that is nonmotile and oxidase and catalase positive. Legionella bacterium is a fastidious organism and will not grow anaerobically on a standard media Microbiology of legionella mnemonic. Flagella: Within the host cell vacuole, legionella are nonmotile, whereas in the later stages of infection and cell lysis, legionella are flagellated and highly motile. Motility enables Legionella to escape from a spent host and facilitates its attempt to find a new host by dispersion into the environment Legionella is a type of bacterium found naturally in freshwater environments, like lakes and streams. It can become a health concern when it grows and spreads in human-made water systems like: Showers and faucets, Cooling towers (air-conditioning units for large buildings), Hot tubs that aren't drained after each use, Decorative fountains and water features, Hot water tanks and heaters, and.

Legionella pneumophila is a Gram-negative bacillus, which means is shaped like a rod, and can be found in many water systems, such as hot water tanks, cooling towers, large air conditioning systems or hot tubs.. It is typically transmitted by inhaling infected aerosols, like contaminated water sprays, jets, or mists and causes a disease called legionellosis with two distinct entities Legionnaires' disease symptoms are similar to other types of pneumonia and it often looks the same on a chest x-ray. Cough. Shortness of breath. Fever. Muscle aches. Headaches. Legionnaires' disease can also be associated with other symptoms such as diarrhea, nausea, and confusion. Symptoms usually begin 2 to 10 days after being exposed to. The most commonly used laboratory test for diagnosis of Legionnaires' disease is the urinary antigen test (UAT), which detects a molecule of the Legionella bacterium in urine. If the patient has pneumonia and the test is positive, then you should consider the patient to have Legionnaires' disease Dec 6, 2009. 307. 5. Status (Visible) Medical Student. Oct 22, 2011. #2.

A drug of choice should be accessible, cost-effective, easily tolerable, safe, and most importantly effective against the disease-causing pathogen Hospital-Acquired Pneumonia. Hospital-acquired pneumonia (HAP) develops at least 48 hours after hospital admission.

  1. Air bronchogram refers to the phenomenon of air-filled bronchi (dark) being made visible by the opacification of surrounding alveoli (grey/white). It is almost always caused by a pathologic airspace/alveolar process, in which something other than air fills the alveoli. Air bronchograms will not be visible if the bronchi themselves are opacified (e.g. by fluid) and thus indicate patent proximal.
