The discriminatory ability of the techniques, first evaluated on 29 unrelated\n            <jats:italic>L. monocytogenes<\/jats:italic>\n            food isolates using Simpson's index of diversity, was 0.714 for PCR-ribotyping, 0.690 for AP-PCR, and 0.919 for IRS-PCR. IRS-PCR was also more capable of distinguishing among strains from the invasive listeriosis outbreak: three different clusters were identified by IRS-PCR compared to two clusters identified by both PCR-ribotyping and AP-PCR. Within each of the two outbreaks of noninvasive listeriosis, the patterns were practically identical, as demonstrated by all three techniques. Only IRS-PCR succeeded in clearly discriminating the strains related to noninvasive listeriosis from all of the other strains included in this study, including those from the outbreak of invasive listeriosis. This finding may suggest the presence of unique differences in their DNA sequences.\n          <\/jats:p>","DOI":"10.1128\/aem.67.4.1793-1799.2001","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T10:00:58Z","timestamp":1027764058000},"page":"1793-1799","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":36,"title":["Characterization of\n            <i>Listeria monocytogenes<\/i>\n            Strains Involved in Invasive and Noninvasive Listeriosis Outbreaks by PCR-Based Fingerprinting Techniques"],"prefix":"10.1128","volume":"67","author":[{"given":"Giovanna","family":"Franciosa","sequence":"first","affiliation":[{"name":"<!--label omitted: 1-->Food Microbiology Laboratory, Food Department, Istituto Superiore di Sanita\u0300, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stefania","family":"Tartaro","sequence":"additional","affiliation":[{"name":"<!--label omitted: 1-->Food Microbiology Laboratory, Food Department, Istituto Superiore di Sanita\u0300, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christina","family":"Wedell-Neergaard","sequence":"additional","affiliation":[{"name":"<!--label omitted: 1-->Food Microbiology Laboratory, Food Department, Istituto Superiore di Sanita\u0300, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paolo","family":"Aureli","sequence":"additional","affiliation":[{"name":"<!--label omitted: 1-->Food Microbiology Laboratory, Food Department, Istituto Superiore di Sanita\u0300, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0168-1605(99)00057-4"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM200004273421702"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199701093360204"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1093\/nar\/26.6.1458"},{"key":"e_1_3_2_6_2","unstructured":"Donnelly\nC.
