What are the neurological effects of Legionnaires disease?

Neurologic involvement in Legionnaires' disease includes encephalitis, meningitis, peripheral nerve disease, and brain stem abnormalities. Patients may present with altered consciousness, hallucinations, delirium, and cerebellar ataxia (2).

What organs does Legionnaires disease affect?

Although Legionnaires' disease primarily affects the lungs, it occasionally can cause infections in wounds and in other parts of the body, including the heart. A mild form of Legionnaires' disease — known as Pontiac fever — can produce fever, chills, headache and muscle aches.

What are the neurological symptoms of Legionella?

Induction of cytokines by Legionella can activate immune cells, especially helper T cells. Th 1 type helper cells that produce type 1 class cytokines, such as interferon gamma and interleukin-2 (IL-2), are known to be important in cellular immunity to Legionella as well as to other opportunistic intracellular bacteria.

Legionella pneumophila is a bacterium that can live a long life cycle that can be separated into two distinct phases. The two phases are known as the replication phase and the dispersal phase. The dispersal phase is the most important and dangerous phase of the legionella life cycle.

Is there a blood test for Legionnaires disease?

Legionella is a type of bacteria that can cause a severe form of pneumonia known as Legionnaires' disease. Legionella tests look for these bacteria in urine, sputum, or blood. Legionnaires' disease got its name in 1976 after a group of people attending an American Legion convention became ill with pneumonia.

How do you test for Legionella in humans?

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.

In full-blown Legionnaires' disease, dry cough, high fever, chills, joint pain, and chest pain quickly develop, followed by pneumonia that starts in one lung but often spreads to the other. Some people may also experience confusion, memory changes, and hallucinations.

Can Legionnaires disease relapse?

Although not commonly reported, the possibility of reinfection with the Legionella bacterium is a reality. The source of human innoculation need not necessarily be a common water supply or large cooling system reservoir (as was previously thought).
