We developed a repetitive-element sequence-based PCR using an IDS-specific primer as a typing method (IDS-PCR) for nonencapsulated\n            <jats:italic>Haemophilus<\/jats:italic>\n            strains and compared this technique with pulsed-field gel electrophoresis (PFGE) of DNA restricted with\n            <jats:italic>Sma<\/jats:italic>\n            I. IDS-PCR was rapid, easy to perform, and reproducible, with a high discriminatory capacity for nontypeable\n            <jats:italic>Haemophilus influenzae<\/jats:italic>\n            (NTHI) strains. The 69 NTHI strains tested generated 65 different banding patterns. Epidemiologically related strains gave similar or identical fingerprints, and all of the unrelated strains except two showed different patterns. These results were in agreement with those obtained by PFGE. For 20 genital strains usually identified as being biotype IV NTHI and belonging to a cryptic genospecies of\n            <jats:italic>Haemophilus<\/jats:italic>\n            with remarkable genetic homogeneity, four bands were significantly present and six bands were significantly absent from the fingerprints. The 20 strains were gathered in 11 closely related profiles, whereas PFGE provided no band when DNA was treated with\n            <jats:italic>Sma<\/jats:italic>\n            I. IDS-PCR improved the differentiation previously obtained within this species by ribotyping and multilocus enzyme electrophoresis. Our findings suggest that IDS-PCR is a rapid, reliable, and discriminatory method for typing NTHI strains and is currently the most efficient method for distinguishing strains within the cryptic genospecies of\n            <jats:italic>Haemophilus<\/jats:italic>\n            .\n          <\/jats:p>","DOI":"10.1128\/jcm.41.8.3473-3480.2003","type":"journal-article","created":{"date-parts":[[2003,8,6]],"date-time":"2003-08-06T20:46:30Z","timestamp":1060202790000},"page":"3473-3480","update-policy":"http:\/\/dx.doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":14,"title":["Typing of Nonencapsulated\n            <i>Haemophilus<\/i>\n            Strains by Repetitive-Element Sequence-Based PCR Using Intergenic Dyad Sequences"],"prefix":"10.1128","volume":"41","author":[{"given":"Guillaume","family":"Bruant","sequence":"first","affiliation":[{"name":"De\u0301partement de Microbiologie Me\u0301dicale et Mole\u0301culaire, Unite\u0301 de Bacte\u0301riologie, Centre Hospitalo-Universitaire Bretonneau, 37044 Tours Cedex, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephane","family":"Watt","sequence":"additional","affiliation":[{"name":"De\u0301partement de Microbiologie Me\u0301dicale et Mole\u0301culaire, Unite\u0301 de Bacte\u0301riologie, Centre Hospitalo-Universitaire Bretonneau, 37044 Tours Cedex, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roland","family":"Quentin","sequence":"additional","affiliation":[{"name":"De\u0301partement de Microbiologie Me\u0301dicale et Mole\u0301culaire, Unite\u0301 de Bacte\u0301riologie, Centre Hospitalo-Universitaire Bretonneau, 37044 Tours Cedex, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Agnes","family":"Rosenau","sequence":"additional","affiliation":[{"name":"De\u0301partement de Microbiologie Me\u0301dicale et Mole\u0301culaire, Unite\u0301 de Bacte\u0301riologie, Centre Hospitalo-Universitaire Bretonneau, 37044 Tours Cedex, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"235","reference":[{"key":"e_1_3_1_2_2","first-page":"227","volume":"14","year":"1996","unstructured":"Aparicio, P., F.
