Malarial screens were negative but C reactive protein, erythrocyte sedimentation rate and neutrophil count were raised and she was anaemic. A new pansystolic murmur was heard over the mitral valve and the transthoracic echocardiogram showed a large vegetation (&gt;1\u2005cm) with at least moderate mitral regurgitation.

CT scan revealed a wedge-shaped area of low attenuation in the spleen in keeping with a splenic infarct. Seven days postadmission, the patient underwent a successful mitral valve repair. Recovery was complicated by a likely embolic infarct in the right frontal lobe, but the patient was discharged 12\u2005days postoperative with no neurological sequelae.<\/jats:p>","DOI":"10.1136\/bcr-2015-212415","type":"journal-article","created":{"date-parts":[[2015,12,11]],"date-time":"2015-12-11T21:30:55Z","timestamp":1449869455000},"page":"bcr2015212415","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["<i>Neisseria elongata<\/i> subsp <i>elongata<\/i> infective endocarditis following endurance exercise"],"prefix":"10.1136","volume":"2015","author":[{"given":"Joanne May","family":"Jenkins","sequence":"first","affiliation":[{"name":"King's College Hospital, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amanda","family":"Fife","sequence":"additional","affiliation":[{"name":"Department of Microbiology, King's College Hospital, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Max","family":"Baghai","sequence":"additional","affiliation":[{"name":"Department of Cardiothoracic Surgery, King's College Hospital, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rafal","family":"Dworakowski","sequence":"additional","affiliation":[{"name":"Department of Cardiology, King's College Hospital, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2015,12,11]]},"reference":[{"key":"2025082801042826000_2015.dec11_1.bcr2015212415.1","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehp285"},{"key":"2025082801042826000_2015.dec11_1.bcr2015212415.2","doi-asserted-by":"publisher","DOI":"10.1128\/JCM.41.7.3436-3437.2003"},{"key":"2025082801042826000_2015.dec11_1.bcr2015212415.3","unstructured":"European Committee on Antimicrobial Susceptibility Testing (EUCAST) Breakpoint Tables for interpretation of MICs and zone diameters, Version 5.0, valid from 1\/1\/2015;
