In this study, 1194 sera from 61 farms located in five different Regions of North-West Italy were collected from slaughtered healthy pigs. Presence of antibody against four <jats:italic>Leptospira<\/jats:italic> serovars was evaluated. Overall, 52.5% of analysed farms presented at least one positive animal and 34.4% presented at least one positive swine with titre \u2a7e1:400. A percentage of 16.6% sera was positive and 5.9% samples presented a positive titre \u2a7e1:400. Tuscany and Lombardy showed the highest percentage of positive farms (64.3% and 54.6%, respectively) and sera (28.5% and 13.3%, respectively), probably due to environmental conditions and potential risk factors, which promote maintenance and spreading of <jats:italic>Leptospira<\/jats:italic> in these areas. The main represented serogroups were Australis (21.3% positive farms, 8.2% positive sera) and Pomona (18.0% positive farms, 8.1% positive sera). In swine, these serogroups are the most detected worldwide; however, our results seem to highlight a reemerging of serogroup Pomona in pigs in investigated areas. A low percentage of sera (0.6%) scored positive to Canicola, leaving an open question on the role of pigs in the epidemiology of this serovar. Higher antibody titres were detected for serogroups Australis and Pomona. Swine leptospirosis is probably underestimated in Italy and could represent a potential risk for animal and human health.<\/jats:p>","DOI":"10.1017\/s0950268818001358","type":"journal-article","created":{"date-parts":[[2018,5,30]],"date-time":"2018-05-30T03:27:32Z","timestamp":1527650852000},"page":"1275-1280","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":16,"title":["Serological survey on <i>Leptospira<\/i> infection in slaughtered swine in North-Central Italy"],"prefix":"10.1017","volume":"146","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5292-0613","authenticated-orcid":false,"given":"F.","family":"Bertelloni","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B.","family":"Turchi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E.","family":"Vattiata","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.","family":"Viola","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.","family":"Pardini","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D.","family":"Cerri","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"F.","family":"Fratini","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2018,5,30]]},"reference":[{"key":"S0950268818001358_ref41","doi-asserted-by":"publisher","DOI":"10.1111\/j.1439-0442.2007.00920.x"},{"key":"S0950268818001358_ref5","doi-asserted-by":"publisher","DOI":"10.1136\/oemed-2014-102457"},{"key":"S0950268818001358_ref40","first-page":"200","article-title":"Guidelines for the identification and development of sampling methods and design of suitable protocols for monitoring of Trichinella infection in indicator species","volume":"44","author":"Pozio","year":"2008","journal-title":"Annali dell'Istituto superiore di sanit\u00e0"},{"key":"S0950268818001358_ref23","unstructured":"Dati forniti dalla BDN dell'Anagrafe Zootecnica istituita dal Ministero della Salute presso il CSN dell'Istituto \u201cG.
