Legionellosis

Introduction: Legionellosis

Description of Legionellosis

Legionellosis (medical condition): Legionella brunensis is a type of bacteria which can cause infection in susceptible humans. Risk factors include diabetes, certain cancers, old age, immunosuppression, emphysema and smoking. Infection is rare and can occur at any age but the elderly or those with a weak immune system are more susceptible. These particular bacteria are commonly found in the environment (e.g. water and soil). Infection usually occurs through inhalation of the bacteria which results in a lung infection called pneumonia or may result in a flu-like illness. The bacteria may also cause respiratory system irritation, inflammation or sensitization. The nature and severity of symptoms may vary amongst patients. Some people may have the bacteria in their body but may have no symptoms. The incubation period lasts from 2 to 10 days but is usually 5 to 6 days. The infection cannot be transmitted from person to person.

Legionellosis: Article Excerpts about Legionella brunensis infection

Legionellosis is an infection caused by the bacterium Legionella pneumophila. The disease has two distinct forms:

• Legionnaires' disease, the more severe form of infection which includes pneumonia, and
• Pontiac fever, a milder illness.

Legionnaires' disease acquired its name in 1976 when an outbreak of pneumonia occurred among persons attending a convention of the American Legion in Philadelphia. Later, the bacterium causing the illness was named Legionella. (Source: excerpt from Legionellosis (General): DBMD)
