Most subjects (31\/33) belonged to families with a proband with confirmed localized juvenile periodontitis (JP); however, most subjects had no evidence of the typical lesions associated with JP. Two additional subjects with rapidly progressive periodontitis, known to be positive for <jats:italic>A. actinomycetemcomitans<\/jats:italic>, were also recruited. The patients with a history of JP had been treated, but were no longer enrolled in a regular maintenance program. With 3 exceptions, the subjects had not received any dental treatment or antibiotics in the past 3 months. One aim of the study was to determine the prevalence of <jats:italic>A. actinomycetemcomitans, P. gingivalis<\/jats:italic>, and <jats:italic>B. forsythus<\/jats:italic> in this population. The main purpose was to compare the relative sensitivity of various methods for detecting these periodontal pathogens. Pooled subgingival plaque samples were collected from all the mesial surfaces and aliquots of the suspension processed for the detection of A. actinomycetemcomitans by culture and indirect immunofluorescence (IF) to serotypes a, b, and c. <jats:italic>P. gingivalis<\/jats:italic> and <jats:italic>B. forsythus<\/jats:italic> were monitored with a DNA probe and IF. With culture, <jats:italic>A. actinomycetemcomitans<\/jats:italic> was detected in 39.4% of the samples, at a mean level of 0.64% of the cultivable counts. With IF, <jats:italic>A. actinomycetemcomitans<\/jats:italic> was detected in 81.8% of the samples, at levels of 0.40, 0.79, and 0.17% of the total counts for serotypes a, b and c respectively. Overall, IF was more likely to detect <jats:italic>A. actinomycetemcomitans<\/jats:italic>, <jats:italic>P. gingivalis<\/jats:italic>, and <jats:italic>B. forsythus<\/jats:italic> than any of the other methods. However, many of the levels of recovery were low. If critical levels of recovery are necessary for disease onset and the culture or probe is sensitive enough to detect the target species at these levels, then the greater sensitivity of IF may not be needed. Nevertheless, until these critical levels are more clearly defined the greater sensitivity of IF may be advantageous. <jats:italic>J Periodontol 1995; 66:158\u2013164.<\/jats:italic><\/jats:p>","DOI":"10.1902\/jop.1995.66.2.158","type":"journal-article","created":{"date-parts":[[2012,3,20]],"date-time":"2012-03-20T20:59:54Z","timestamp":1332277194000},"page":"158-164","source":"Crossref","is-referenced-by-count":23,"title":["Detection of <i>Actinobacillus actinotnycetemcomitans, Porphyromonas gingivalis<\/i>, and <i>Bacteroides forsythus<\/i> in an <i>A. actinomycetemcomitans<\/i>\u2010Positive Patient Population"],"prefix":"10.1002","volume":"66","author":[{"given":"M.A.","family":"Listgarten","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.\u2010Y.","family":"Wong","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C\u2010H.","family":"Lai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[1995,2]]},"container-title":["Journal of Periodontology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/aap.onlinelibrary.wiley.com\/doi\/pdf\/10.1902\/jop.1995.66.2.158","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,19]],"date-time":"2025-10-19T08:47:33Z","timestamp":1760863653000},"score":1,"resource":{"primary":{"URL":"https:\/\/aap.onlinelibrary.wiley.com\/doi\/10.1902\/jop.1995.66.2.158"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1995,2]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[1995,2]]}},"alternative-id":["10.1902\/jop.1995.66.2.158"],"URL":"https:\/\/doi.org\/10.1902\/jop.1995.66.2.158","archive":["Portico"],"relation":{},"ISSN":["0022-3492","1943-3670"],"issn-type":[{"value":"0022-3492","type":"print"},{"value":"1943-3670","type":"electronic"}],"subject":[],"published":{"date-parts":[[1995,2]]}}}
