Abstract
Abstract: The distribution of serotypes and ribotypes of mutans streptococcal isolates obtained from seven unrelated children at 5 and at 10 or 12yr of age was investigated. For ribotyping, chromosomal DNA from 5 to 13 isolates per subject was digested with restriction endonucleases Eco RI and HindIII. The DNA fragments were electrophoretically separated, blotted on to nylon membrane and hybridized to the plasmid pKK3535, which contains the rRNA operon of the Escherichia coli chromosome. The ribotypes were unique for each child. In five children only one ribotype and serotype (c, e or f) was found. In one child two serotypes (c and f) were found at baseline and only one (serotype c) in the follow-up sample. In one child the same serotype was not found in the baseline (serotype e) and in the follow-up (serotype c) samples. Every child except one had a ribotype that was identical to one found 5–7 yr later. The results suggest that, at the age of 5 yr, infection by Streptococcus mutans has already stabilized and the colonizing strain remains permanent.

For ribotyping, chromosomal DNA from 5 to 13 isolates per subject was digested with restriction endonucleases Eco RI and HindIII. The DNA fragments were electrophoretically separated, blotted on to nylon membrane and hybridized to the plasmid pKK3535, which contains the rRNA operon of the Escherichia coli chromosome. The ribotypes were unique for each child. In five children only one ribotype and serotype (c, e or f) was found. In one child two serotypes (c and f) were found at baseline and only one (serotype c) in the follow-up sample. In one child the same serotype was not found in the baseline (serotype e) and in the follow-up (serotype c) samples. Every child except one had a ribotype that was identical to one found 5–7 yr later. The results suggest that, at the age of 5 yr, infection by Streptococcus mutans has already stabilized and the colonizing strain remains permanent.</p></abstract><textClass xml:lang="en"><keywords scheme="keyword"><list><head>Keywords</head><item><term>Streptococcus mutans</term></item><item><term>serotyping</term></item><item><term>ribotyping</term></item><item><term>infection stability</term></item><item><term>children</term></item></list></keywords></textClass></profileDesc><revisionDesc><change when="1994">Published</change></revisionDesc></teiHeader></istex:fulltextTEI><json:item><extension>txt</extension><original>false</original><mimetype>text/plain</mimetype><uri>https://api.istex.fr/document/AE4E145385AFDB2964EE5170CBBC4CD67E615ADA/fulltext/txt</uri></json:item></fulltext><metadata><istex:metadataXml wicri:clean="Elsevier, elements deleted: tail"><istex:xmlDeclaration>version="1.0" encoding="UTF-8"</istex:xmlDeclaration><istex:docType PUBLIC="-//ES//DTD journal article DTD version 4.5.2//EN//XML" URI="art452.dtd" name="istex:docType"></istex:docType><istex:document><converted-article version="4.5.2" docsubtype="fla" xml:lang="en"><item-info><jid>AOB</jid><aid>94901422</aid><ce:pii>0003-9969(94)90142-2</ce:pii><ce:doi>10.1016/0003-9969(94)90142-2</ce:doi><ce:copyright type="unknown" year="1994"></ce:copyright></item-info><head><ce:title>The demonstration by ribotyping of the stability of oral <ce:italic>Streptococcus mutans</ce:italic> infection over 5 to 7 years in children</ce:title><ce:author-group><ce:author><ce:given-name>S.</ce:given-name><ce:surname>Alaluusua</ce:surname><ce:cross-ref refid="AFF1"><ce:sup loc="post">1</ce:sup></ce:cross-ref></ce:author><ce:author><ce:given-name>S.J.</ce:given-name><ce:surname>Alaluusua</ce:surname><ce:cross-ref refid="AFF2"><ce:sup loc="post">2</ce:sup></ce:cross-ref></ce:author><ce:author><ce:given-name>J.</ce:given-name><ce:surname>Karjalainen</ce:surname><ce:cross-ref refid="AFF2"><ce:sup loc="post">2</ce:sup></ce:cross-ref></ce:author><ce:author><ce:given-name>M.</ce:given-name><ce:surname>Saarela</ce:surname><ce:cross-ref refid="AFF2"><ce:sup loc="post">2</ce:sup></ce:cross-ref></ce:author><ce:author><ce:given-name>T.</ce:given-name><ce:surname>Holttinen</ce:surname><ce:cross-ref refid="AFF2"><ce:sup loc="post">2</ce:sup></ce:cross-ref></ce:author><ce:author><ce:given-name>M.</ce:given-name><ce:surname>Kallio</ce:surname><ce:cross-ref refid="AFF3"><ce:sup loc="post">3</ce:sup></ce:cross-ref></ce:author><ce:author><ce:given-name>P.</ce:given-name><ce:surname>Hölttä</ce:surname><ce:cross-ref refid="AFF1"><ce:sup loc="post">1</ce:sup></ce:cross-ref></ce:author><ce:author><ce:given-name>H.</ce:given-name><ce:surname>Torkko</ce:surname><ce:cross-ref refid="AFF2"><ce:sup loc="post">2</ce:sup></ce:cross-ref></ce:author><ce:author><ce:given-name>P.</ce:given-name><ce:surname>Relander</ce:surname><ce:cross-ref refid="AFF2"><ce:sup loc="post">2</ce:sup></ce:cross-ref></ce:author><ce:author><ce:given-name>S.</ce:given-name><ce:surname>Asikainen</ce:surname><ce:cross-ref refid="AFF4"><ce:sup loc="post">4</ce:sup></ce:cross-ref></ce:author><ce:affiliation id="AFF1"><ce:label>1</ce:label><ce:textfn>Department of Pedodontics and Orthodontics, P.O.
