Occurrence and distribution of Legionella species in composted plant materials.
Legionellae were found in many samples of composted plant matter obtained from home gardeners and from facilities which undertook bulk composting. The predominant species isolated from these composts was Legionella pneumophila, the strains of which belonged to serogroups other than serogroup 1. Other Legionella species were present in many samples. Legionella longbeachae serogroup 1, which is implicated in human infections in South Australia, was present in samples obtained from two of six facilities composting large volumes of material and from 3 of 30 gardeners. Many of the species or strains isolated from composts have not been implicated as causative agents of legionellosis in South Austrailia, but some cause infection in healthy and immunosuppressed persons.
