The 21 high-risk workers were compared with 27 low-risk workers, persons who were not directly involved in service or maintenance for the company. The overall prevalence of titers greater than or equal to 128 for the 21 high-risk workers was 19.0% compared with 22.2% for the low-risk group. There were no significant differences in the history of pneumonia between these groups. Possible explanations for these findings are discussed.<\/jats:p>","DOI":"10.1128\/aem.40.1.114-116.1980","type":"journal-article","created":{"date-parts":[[2020,1,1]],"date-time":"2020-01-01T03:04:03Z","timestamp":1577847843000},"page":"114-116","update-policy":"http:\/\/dx.doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":9,"title":["Are air-conditioning maintenance personnel at increased risk of Legionellosis?"],"prefix":"10.1128","volume":"40","author":[{"given":"W D","family":"Goldman","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J S","family":"Marr","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"235","container-title":["Applied and Environmental Microbiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.asm.org\/doi\/pdf\/10.1128\/aem.40.1.114-116.1980","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.asm.org\/doi\/pdf\/10.1128\/aem.40.1.114-116.1980","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,2,23]],"date-time":"2022-02-23T20:25:20Z","timestamp":1645647920000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.asm.org\/doi\/10.1128\/aem.40.1.114-116.1980"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1980,7]]},"references-count":0,"journal-issue":{"issue":"1","published-print":{"date-parts":[[1980,7]]}},"alternative-id":["10.1128\/aem.40.1.114-116.1980"],"URL":"https:\/\/doi.org\/10.1128\/aem.40.1.114-116.1980","relation":{},"ISSN":["0099-2240","1098-5336"],"issn-type":[{"value":"0099-2240","type":"print"},{"value":"1098-5336","type":"electronic"}],"subject":[],"published":{"date-parts":[[1980,7]]},"assertion":[{"value":"1980-07-01","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
