Legionellosis
|
|
Legionellosis Legionellosis is an infection caused by species of the bacterium Legionella, most notably L. pneumophila. At least 46 species and 70 serogroups have been identified. L. pneumophila, an ubiquitous aquatic organism that thrives in warm environments (32 - 45 C) causes over 90% of Legionnaires Disease in the United States.

Infection
Anything that invades the body and reproduces. Infections can be bacteria, protozoa, fungi, or viruses. Bacteria and fungi are one celled creatures that cause many infections including strep throat, bladder infections, and some lung infections. Fungi cause “athlete’s foot” and thrush, an infection in the mouth. Protozoa are small organisms with many cells that can cause infections in the guts or in the lungs. Most healthy people do not get protozoal infections, but people with suppressed immune systems can. Viruses are not really organisms; they are tiny particles that can live only inside another cell. They reproduce by taking over a cell and causing that cell to make more virus particles, rather than doing what the cell is supposed to do. Viruses cause most colds and flu cases.
Bacterium
The singular of bacteria.
Legionella
See Legionellosis.
Organism
A living thing, such as an animal, a plant, a bacterium, or a fungus.
Disease
Illness or sickness often characterized by typical patient problems (symptoms) and physical findings (signs). Disruption sequence: The events that occur when a fetus that is developing normally is subjected to a destructive agent such as the rubella (German measles) virus.

Legionnaire disease
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
PREVIOUS AND NEXT TERMS--------------------------------------
Lustral
A commercial name for sertraline hydrochloride, an orally administered antidepressant of the selective serotonin reuptake inhibitor (SSRI) type. Sertraline is used medically mainly to treat the symptoms of depression.
Lacunae
One of many small cavities uniformly spaced along the lamellae of bones. In living bone, each lacuna contains one bone cell known as an osteocyte. Small canals (canaliculi) radiate from the lacunae and in these are small protoplasmic processes that connect with the osteoblast in other lacunae.
Lymphocyte
White blood cell. Lymphocytes have a number of roles in the immune system, including antibody production, attacking and destroying cancer cells, and producing substances that kill cancer cells.
Lyme Disease
A bacterial disease caused by the micro-organism (spirochete) Borrelia burgdorferi. This bacterium was discovered in 1982, although the clinical disease was first described in 1977. Infection occurs after the bite of an infected tick. The incubation period is approximately 14 days. Symptoms include a large circular red rash at the bite site (50-60% of cases), malaise, fever, headache, muscle aches and swollen lymph nodes. If untreated may progress to arthritis and compromise heart function. Some symptoms and signs of Lyme disease may not appear until weeks, months, or years after a tick bite. Early Lyme disease can usually be correctly diagnosed, but a delayed response or recurrence of this disorder may be mistaken for fibromyalgia. Some experts believe that between 15% and 50% of patients referred to clinics for Lyme disease actually have fibromyalgia. Late Lyme disease can usually (but not always) be ruled out using laboratory tests that identify the spirochete that causes this tick-borne disease. If fibromyalgia patients are incorrectly diagnosed and treated for Lyme disease with prolonged courses of antibiotics, the drugs may have serious side effects.
Lou Gehrig's Disease
Motor Neurone Disease (MND) is a term used to cover a number of illnesses of the motor neurone. Amyotrophic Lateral Sclerosis (ALS), Progressive Muscular Atrophy (PMA), Progressive Bulbar Palsy (PBP) and Progressive Lateral Sclerosis (PLS) are all types of MND. MND is the term used internationally while ALS is often used in the United States (where it is also known as Lou Gehrig's disease) to cover all forms of MND. It was first described by Jean-Martin Charcot, a French neurologist, in 1869.
Legionellosis
Lorcet
Hydrocodone (chemical synonym: dihydrocodeinone; trade names: Vicodin, Anexsia, Dicodid, Hycodan, Hycomine, Lorcet, Lortab, Norco, Tussionex) is an opioid derived from either of the natural occuring opiates -- codeine or thebaine. Hydrocodone is an orally active analgesic and antitussive Schedule II narcotic which is marketed in multi-ingredient Schedule III products. The therapeutic dose of 5 mg to 10 mg is pharmacologically equivalent to 30 to 60 mg of oral codeine.
Lortab
Hydrocodone (chemical synonym: dihydrocodeinone; trade names: Vicodin, Anexsia, Dicodid, Hycodan, Hycomine, Lorcet, Lortab, Norco, Tussionex) is an opioid derived from either of the natural occuring opiates -- codeine or thebaine.

Lumpectomy
Surgical removal of a small cancerous or non-cancerous tumor; generally used to refer to removal of a breast lump.
Levodopa
L-dopa. The single most effective anti-Parkinson drug, it is changed into dopamine in the brain.
