伴放线放线杆菌是一种革兰氏阴性的口腔微生物，它与局限性青少年牙周炎和严重的医学感染如细菌性心内膜炎的病因有关。本研究评价牙周探针传播A.从青少年牙周炎病变到健康龈沟的同一患者的放线菌共生。局部青少年牙周炎患者表现为第一磨牙和切牙牙槽骨丢失，并有大量的A。本研究包括牙周深袋中的伴放线菌。将牙周探针插入6mm或更深的牙周袋中。然后将探针置于同一受试者的健康龈沟中3 mm或更小，进行55次探针转移，A。通过选择性培养技术评估供体和受体部位中的伴放线菌。牙周膜探针显然可以被A. 在常规牙科检查中，伴随放线菌的细菌可从青少年牙周炎病变中分离出来，并可将这种微生物从感染部位转移到先前未感染的部位。但是，A.接种到健康龈沟中的伴放线菌没有永久地定殖这些部位，因为这些生物体在3周内被消除。
Actinobacillus actinomycetemcomitans is a gram-negative oral microorganism, which has been implicated in the etiology of localized juvenile periodontitis and in severe medical infections such as bacterial endocarditis. This study evaluated the ability of periodontal probes to transmit A. actinomycetemcomitans from juvenile periodontitis lesions to healthy gingival sulci in the same patient. Localized juvenile periodontitis patients exhibiting 1st molar and incisor alveolar bone loss and with large numbers of A. actinomycetemcomitans in deep periodontal pockets were included in this study. A periodontal probe was inserted into periodontal pockets of 6 mm or greater depth. The probe was then placed into a healthy gingival sulcus of 3 mm or less, in the same subjects; 55 transfers by probing were made and A. actinomycetemcomitans in the donor and recipient sites was assessed by a selective culture technique. Periodontal probes evidently can become contaminated with A. actinomycetemcomitans from juvenile periodonitis lesions during routine dental examinations and can transfer this microorganism from infected to previously uninfected sites. However, A. actinomycetemcomitans inoculated into the healthy gingival sulci did not permanently colonize these sites since the organisms were eliminated within 3 wk.
