[Isolation and identification of oral spirochaetes and Fusobacterium in juvenile periodontitis].
Periodontal pocket specimens of 40 juveniles periodontitis (JP) and specimens from gingival sulcus in 40 normal juveniles (NP) were examined. 25 strains of anaerobic oral spirochaete (62.5%) (17 strains were Treponema microdentium, 3 strains macrodentium, 2 strains T orale, 3 strains Borrelia) and 21 strains of fusobacterium were isolated in 40 JP. In 40 NP, 2 strains of spirochaetes (5%) and 3 strains fusobacterium (7.5%) were found. This study shows that there is a relationship between the infection of spirochaeta, fusobacterium and JP.
