Some species support the growth of strains from serogroups 1 to 6, others only strains from certain serogroups. Initial studies with seeded material indicate that amoebal enrichment could be utilised for the isolation of legionellae from clinical specimens and natural habitats. It is suggested that a vacuole, or amoeba, full of legionellae, rather than free legionellae, could be the infective particle for man.<\/jats:p>","DOI":"10.1136\/jcp.33.12.1179","type":"journal-article","created":{"date-parts":[[2007,6,9]],"date-time":"2007-06-09T04:50:46Z","timestamp":1181364646000},"page":"1179-1183","source":"Crossref","is-referenced-by-count":868,"title":["Preliminary report on the pathogenicity of Legionella pneumophila for freshwater and soil amoebae."],"prefix":"10.1136","volume":"33","author":[{"given":"T J","family":"Rowbotham","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[1980,12,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"664","DOI":"10.7326\/0003-4819-90-4-664","article-title":"Isolation of the Legionnaires' disease bacterium from environmental samples","volume":"90","author":"Morris, G.K.; Patton, C.M.; Feeley, J.C.","year":"1979","unstructured":"Morris GK, Patton CM, Feeley JC, et al.
