actinobacillus actinomycetemcomitans count in patients with adult periodontitis
periodontal infections are categorized into various groups based on patient’s age or bacteria presented in dental pockets. there are juvenile periodontitis, rapidly progressing periodontitis and adult periodontitis. adult periodontitis is known as the most prevalent cause of tooth loss in adult patients. in current study, 100 teeth of patients who suffered from adult periodontistis were selecte...
متن کاملAggregatibacter Actinomycetemcomitans and Prevotella Intermedia in Advanced Chronic Periodontitis Patients
This cross-sectional study was carried out to identify A. actinomycetemcomitans and P. intermedia in the subgingival plaque of three ethnic groups (Malays, Chinese and Indians) in a selected group of adult Malaysians with advanced Chronic Periodontitis and to correlate these findings with their periodontal status. Thirty periodontally diseased adults were age, gender and ethnically matched with...
متن کاملPopulation structure and genetic diversity of Actinobacillus actinomycetemcomitans strains isolated from localized juvenile periodontitis patients.
The phylogeny of 20 Actinobacillus actinomycetemcomitans strains isolated from patients with localized juvenile periodontitis (LJP) was investigated by using partial sequence analysis of 16S rRNA genes, arbitrarily primed PCR (AP-PCR), and four additional PCR assays that amplified polymorphic regions in the leukotoxin (lkt), cytolethal distending toxin (cdt), major fimbrial subunit (flp-1), and...
متن کاملOpsonic antibody activity against Actinobacillus actinomycetemcomitans in patients with rapidly progressive periodontitis.
Actinobacillus actinomycetemcomitans has been closely associated with early-onset, severe periodontitis, and such patients often have serum immunoglobulin G (IgG) antibodies reactive with antigens of this gram-negative pathogen. We examined the functionality and potential importance of these antibodies. The opsonic activity against A. actinomycetemcomitans of sera from 30 patients with rapidly ...
متن کاملColonial variation and fimbriation of Actinobacillus actinomycetemcomitans.
Three colonial variants of Actinobacillus actinomycetemcomitans, which formed transparent rough (TR)-, transparent smooth (TS)-, and opaque smooth (OS)-surfaced colonies, were described in relation to their fimbriation. TR- and TS-cells were adhesive to agar and glass surfaces but not the OS-cells. The examination by electron microscopy revealed that TR-cells were highly fimbriated but not TS- ...
