Data on the presence of Legionellae outside the aquatic environment are scarce. Alternative ecosystems that could act as a reservoir for Legionella spp. have been investigated to identify unconventional contaminated substrates that are able to produce bioaerosols. We considered eight green waste collection sites including three composting facilities. Legionella pneumophila sg 1-15, Legionella bozemanii, Legionella cincinnatiensis, Legionella jamestowniensis, Legionella micdadei and L. oakridgensis were isolated from samples taken at six of the eight sites. The degree of contamination ranged from 10(3) to 10(8) CFU/g. Compost facilities appear to comprise an important reservoir for Legionellae.

UI	MeSH Term	Description	Entries

D015169	Colony Count, Microbial	Enumeration by direct count of viable, isolated bacterial, archaeal, or fungal CELLS or SPORES capable of growth on solid CULTURE MEDIA. The method is used routinely by environmental microbiologists for quantifying organisms in AIR; FOOD; and WATER; by clinicians for measuring patients' microbial load; and in antimicrobial drug testing.
