We reported thet oral bacteria in dental plaque were arrested to penetrate into periodontal tissue by secretory IgA coating to the bacteria.<br>In this study, the presence and degree of non-specific coating of secretory IgA to Bacteroides melaninogenicus subsp asacchalolyticus, Bacterionema matruchotii, Lactobacillus casei, Neisseria subflava, Peptostreptococcus anaerobius, Propionibacterium aches and Veillonella alcalescens were investigated. The results were as follow, Neisseria subflava, Veillonella alcalescens and Peptostreptococcus anaerobius showed intensive fluorescence on their cell walls. Propionibacterium acenes, Bacterionema matruchotii and Lactobacillus casei showed small granular and scattered fluorescence on their cell walls. However, specific fluorescence was not demonstrated on Bacteroides melaninogenicus subsp asacchalolyticus.
