For this reason, epidemiological and clinical studies focusing on disease characterization are widely advocated. The aim of this study was to characterize the leptospires identified in dogs with confirmed symptomatic acute leptospirosis. Leptospira spp. DNA detected in urine, blood, or both samples from nine infected dogs was analyzed using the multi-locus sequence typing (MLST) technique. Leptospires from two dogs were successfully typed: one was identified as belonging to Sequence Type (ST) 17 and one to ST198, both within the L. interrogans species, serogroups Icterohaemorrhagiae and Australis, respectively. Based on the results of routine serologic tests, antibodies reactive toward these serogroups are commonly revealed in dogs in Italy. This study provides the first molecular analysis that identifies infecting Leptospira directly on DNA from biological samples of dogs, showing that serogroup Australis can lead to a severe clinical presentation of leptospirosis in infected dogs.<\/jats:p>","DOI":"10.3390\/pathogens9050351","type":"journal-article","created":{"date-parts":[[2020,5,7]],"date-time":"2020-05-07T03:10:38Z","timestamp":1588821038000},"page":"351","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Identification of Serogroups Australis and Icterohaemorrhagiae in Two Dogs with a Severe Form of Acute Leptospirosis in Italy"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8049-6645","authenticated-orcid":false,"given":"Andrea","family":"Balboni","sequence":"first","affiliation":[{"name":"Department of Veterinary Medical Sciences, Alma Mater Studiorum, University of Bologna, 40064 Ozzano dell\u2019Emilia, Bologna, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Silvia","family":"Zamagni","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medical Sciences, Alma Mater Studiorum, University of Bologna, 40064 Ozzano dell\u2019Emilia, Bologna, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1082-982X","authenticated-orcid":false,"given":"Cristina","family":"Bertasio","sequence":"additional","affiliation":[{"name":"National Reference Centre for Animal Leptospirosis (NRCL), Istituto Zooprofilattico Sperimentale della Lombardia ed Emilia Romagna \u201cBruno Ubertini\u201d, via Bianchi 7\/9, 25121 Brescia, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria Beatrice","family":"Boniotti","sequence":"additional","affiliation":[{"name":"National Reference Centre for Animal Leptospirosis (NRCL), Istituto Zooprofilattico Sperimentale della Lombardia ed Emilia Romagna \u201cBruno Ubertini\u201d, via Bianchi 7\/9, 25121 Brescia, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roberta","family":"Tro\u00eca","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medical Sciences, Alma Mater Studiorum, University of Bologna, 40064 Ozzano dell\u2019Emilia, Bologna, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mara","family":"Battilani","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medical Sciences, Alma Mater Studiorum, University of Bologna, 40064 Ozzano dell\u2019Emilia, Bologna, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8259-6458","authenticated-orcid":false,"given":"Francesco","family":"Dondi","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medical Sciences, Alma Mater Studiorum, University of Bologna, 40064 Ozzano dell\u2019Emilia, Bologna, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,5,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"757","DOI":"10.1016\/S1473-3099(03)00830-2","article-title":"Leptospirosis: A zoonotic disease of global importance","volume":"3","author":"Bharti","year":"2003","journal-title":"Lancet Infect.
