"Legionella longbeachae" is one
speciesof the family Legionellaceae. It is found predominantly in soil and potting compost. Human infection from "L. longbeachae" is particularly common in Western Australia,cite journal | author=Alli OA, Zink S, von Lackum NK, Abu-Kwaik Y | title=Comparative assessment of virulence traits in "Legionella" spp | journal=Microbiology | year=2003 | pages=631–41 | volume=149 | issue=Pt 3 | pmid=12634332 | doi=10.1099/mic.0.25980-0 ] ,cite journal | author=Grove DI, Lawson PJ, Burgess JS, Moran JL, O'Fathartaigh MS, Winslow WE | title=An outbreak of "Legionella longbeachae" infection in an intensive care unit? | journal=J Hosp Infect | year=2002 | pages=250–8 | volume=52 | issue=4 | pmid=12473468 | doi=10.1053/jhin.2002.1322 ] yet cases have been documented in other countries including the USA.cite journal | author= | title=Legionnaires' Disease associated with potting soil--California, Oregon, and Washington, May-June 2000 | journal=MMWR Morb Mortal Wkly Rep | year=2000 | pages=777–8 | volume=49 | issue=34 | pmid=10987244 [http://www.cdc.gov/mmwr/preview/mmwrhtml/mm4934a1.htm fulltext] ]
Like other "
Legionella" species, person-to-person transmission has not been documented. However, unlike other species the primary transmission mode is inhalation of dust from contaminated compost or soil that contains the organismcausing legionellosis.cite journal | author=Steele TW, Lanser J, Sangster N | title=Isolation of "Legionella longbeachae" serogroup 1 from potting mixes | journal=Appl Environ Microbiol | year=1990 | pages=49–53 | volume=56 | issue=1 | pmid=1968736 ]
Compost must be handled with care, damp down with water to reduce dust before handling, use a face mask covering nose and mouth to reduce the risk of inhaling the dust, especially for those at high risk from infection.
It is noteworthy that compost packaging in
Australiahas a "L. longbeachae" warning label.
