New Zealand has the highest reported incidence of Legionnaires' disease in the world (1), and in part because of the more rigorous testing in this country, the epidemiology of detected Legionnaires' disease in New Zealand differs from that of most other countries; a high proportion of cases are caused by L. longbeachae (3-5).
Two small case-control studies on risk factors for L. longbeachae pneumonia conducted in South Australia have been published (10,11).
pneumophila serogroups 2-15, and seven other Legionella species (L. longbeachae 1 and 2, L.

On June 13, 2000, CDC was alerted by a county health official in Washington of L. longbeachae infection in a 46-year-old woman who had been hospitalized with pneumonia.
In May, two L. longbeachae isolates had been received at CDC from bronchial wash samples taken from both a 77-year-old Oregon woman and a 45-year-old California man who were both diagnosed with legionellosis.
In Australasia, New Zealand, and some countries in Asia, infections caused by L. longbeachae occur at comparable levels to infections caused by L.
The number of legionellosis cases caused by L. longbeachae is increasing worldwide (7), with a notable rise reported across Europe (9-11).
