The overall antibody prevalence varied from 14% to 66%; however, the age distribution of MA test titres was remarkably similar in all 4 populations. Antibody prevalence was similar in both males and females and demonstrable antibodies wore limited to sexually mature animals. The greater prevalence of high titres (\u2265 1:128) in the 18\u2010 to 24\u2010month age group suggested that primary infections were acquired at this age. The findings suggested that infection was maintained in possum populations by direct transmission, probably associated with breeding. Focal interstitial nephritis was observed in kidneys of possums greater than 18 months of age and was associated with MA titres to <jats:italic>hardjo<\/jats:italic> (P &lt; 0.001). Serovar <jats:italic>balcanica<\/jats:italic> was isolated from possum kidneys from 2 of these populations, suggesting that <jats:italic>balcanica<\/jats:italic> infections were responsible for most of the <jats:italic>hardjo<\/jats:italic> titres. However, agglutinin\u2010absorption tests indicated that some possums may be infected with a leptospire more closely related to <jats:italic>hardjo<\/jats:italic> than to <jats:italic>balcanica<\/jats:italic>.<\/jats:p>","DOI":"10.1038\/icb.1979.20","type":"journal-article","created":{"date-parts":[[2007,11,27]],"date-time":"2007-11-27T10:04:39Z","timestamp":1196157879000},"page":"191-201","source":"Crossref","is-referenced-by-count":10,"title":["A SERO\u2010EPIDEMIOLOGICAL STUDY OF <i>LEPTOSPIRA INTERROGANS<\/i> SEROVAR <i>BALCANICA<\/i> IN FOUR BRUSH\u2010TAILED POSSUM POPULATIONS IN VICTORIA, AUSTRALIA"],"prefix":"10.1111","volume":"57","author":[{"given":"Philip T","family":"Durfee","sequence":"first","affiliation":[{"name":"Department of Veterinary Paraclinical Sciences, University of Melbourne, Veterinary Clinical Centre Werribee Victoria Australia 3030"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul JA","family":"Presidente","sequence":"additional","affiliation":[{"name":"Department of Veterinary Paraclinical Sciences, University of Melbourne, Veterinary Clinical Centre Werribee Victoria Australia 3030"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[1979,4]]},"container-title":["Australian Journal of Experimental Biology and Medical Science"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1038%2Ficb.1979.20","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/www.nature.com\/articles\/icb197920","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/www.nature.com\/articles\/icb197920.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1038\/icb.1979.20","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"},{"URL":"http:\/\/www.nature.com\/articles\/icb197920.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,29]],"date-time":"2023-09-29T22:30:56Z","timestamp":1696026656000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1038\/icb.1979.20"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1979,4]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[1979,4]]}},"alternative-id":["10.1038\/icb.1979.20"],"URL":"https:\/\/doi.org\/10.1038\/icb.1979.20","archive":["Portico"],"relation":{},"ISSN":["0818-9641"],"issn-type":[{"value":"0818-9641","type":"print"}],"subject":[],"published":{"date-parts":[[1979,4]]}}}
