Clinical significance:
Legionella infection is associated with 2 clinically and epidemiologically distinct illnesses. Legionnaires disease and Pontiac fever. Legionnaires disease is characterized by fever, cough, myalgia, and pneumonia, whereas, Pontiac fever is a milder illness without pneumonia. Inhaling aerosols of water contaminated with Legionella species is believed to be the primary mode of infection; the incubation period is generally 2-10 days. A 4-fold rise in IgG IFA Antibody titer to >1:128 between acute and convalescent sera may be used in the laboratory confirmation of Legionella infection.
