Rapid test for the qualitative detection of Legionella pneumophila antigen in urine samples. For professional in vitro diagnostic use only. The Legionella pneumophila Rapid Test Cassette (Urine) is an immunochromatographic in vitro diagnostic test. It is designed to detect the soluble Legionella pneumophila serogroup 1 antigen in human urine samples. Legionellosis is severe pneumonia caused by bacteria of the genus Legionella assigned to the Legionellaceae family. This family now includes 48 species and over 60 serogroups. About 20 species are implicated in human diseases. The vast majority of Legionella infections are caused by Legionella pneumophila. Legionnaires’ disease is the main clinical manifestation of Legionella infection, although extra pulmonary infections and non-pulmonary diseases such as Pontiac fever do occur. The name Legionella pneumophila is derived from the dramatic epidemiological outbreak following the 1976 American Legion Convention in Philadelphia. Legionella pneumophila is responsible for approximately 90% of infections and of these over 80% is due to a single serogroup, serogroup. Legionella is a Gram-negative bacterium with the shape of small rods which has polar flagella. Legionella bacteria have a widespread proliferation in both natural and artificial aquatic habitats. They are readily available in fresh water, cooling towers and drinking water systems. Organisms can survive in a wide range of conditions and temperature is a determining factor for the proliferation of Legionella. Nosocomial infection is particularly associated with legionella colonization of the hospital hot water system.
