Although <jats:italic>F. tularensis<\/jats:italic> has a low infectious dose and high associated mortality, it possesses few classical virulence factors. An analysis of the <jats:italic>F. tularensis<\/jats:italic> subspecies <jats:italic>tularensis<\/jats:italic> genome sequence has revealed the presence of a region containing genes with low sequence homology to part of the <jats:italic>capBCADE<\/jats:italic> operon of <jats:italic>Bacillus anthracis<\/jats:italic>. We have generated an isogenic <jats:italic>capB<\/jats:italic> mutant of <jats:italic>F. tularensis<\/jats:italic> subspecies <jats:italic>tularensis<\/jats:italic> SchuS4 and shown it to be attenuated. Furthermore, using BALB\/c mice, we have demonstrated that this <jats:italic>capB<\/jats:italic> strain affords protection against significant homologous challenge with the wild-type strain. These data have important implications for the development of a defined and efficacious tularaemia vaccine.<\/jats:p>","DOI":"10.1099\/jmm.0.018911-0","type":"journal-article","created":{"date-parts":[[2010,7,23]],"date-time":"2010-07-23T02:25:22Z","timestamp":1279851922000},"page":"1275-1284","source":"Crossref","is-referenced-by-count":19,"title":["Deletion of the Bacillus anthracis capB homologue in Francisella tularensis subspecies tularensis generates an attenuated strain that protects mice against virulent tularaemia"],"prefix":"10.1099","volume":"59","author":[{"given":"Stephen L.","family":"Michell","sequence":"first","affiliation":[{"name":"Biomedical Sciences, Defence Science and Technology Laboratory, Porton Down, Salisbury, Wiltshire SP4 0JQ, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rachel E.","family":"Dean","sequence":"additional","affiliation":[{"name":"Biomedical Sciences, Defence Science and Technology Laboratory, Porton Down, Salisbury, Wiltshire SP4 0JQ, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jim E.","family":"Eyles","sequence":"additional","affiliation":[{"name":"Biomedical Sciences, Defence Science and Technology Laboratory, Porton Down, Salisbury, Wiltshire SP4 0JQ, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Margaret Gill","family":"Hartley","sequence":"additional","affiliation":[{"name":"Biomedical Sciences, Defence Science and Technology Laboratory, Porton Down, Salisbury, Wiltshire SP4 0JQ, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emma","family":"Waters","sequence":"additional","affiliation":[{"name":"Biomedical Sciences, Defence Science and Technology Laboratory, Porton Down, Salisbury, Wiltshire SP4 0JQ, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joann L.","family":"Prior","sequence":"additional","affiliation":[{"name":"Biomedical Sciences, Defence Science and Technology Laboratory, Porton Down, Salisbury, Wiltshire SP4 0JQ, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard W.","family":"Titball","sequence":"additional","affiliation":[{"name":"Biomedical Sciences, Defence Science and Technology Laboratory, Porton Down, Salisbury, Wiltshire SP4 0JQ, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Petra C.
