Última Analysis of leukotoxin gene types of Actinobacillus actinomycetemcomitans in brazilians with aggressive periodontitis BJM Rosalem Junior,Wilson; Souza,Rodrigo Carvalho de; Andrade,Arnaldo Feitosa Braga de; Colombo,Ana Paula Vieira. Actinobacillus actinomycetemcomitans (Aa) is considered a major etiologic agent of aggressive periodontitis but this species has also been associated with other forms of periodontal disease. Further, highly leukotoxic strains are related to severity of disease. The purpose of this study was to determine the prevalence of Aa and the occurrence of the leukotoxin gene 530-bp deletion in patients with generalized aggressive periodontitis (GAP) from a Brazilian population. Thirty periodontally healthy and 29 GAP subjects participated in the study. Full-mouth periodontal examination including probing pocket depth (PPD), clinical attachment level (CAL), supragingival biofilm (SB) and bleeding on probing (BOP) was carried out at 6 sites/tooth for all subjects....

Aggregatibacter actinomycetemcomitans is an important etiologic agent of the periodontitis and is associated with extra-oral infections. In this study, the detection of the ltxA gene as well as the ltx promoter region from leukotoxic A. actinomycetemcomitans isolated from 50 Brazilian patients with periodontitis and 50 healthy subjects was performed. The leukotoxic activity on HL-60 cells was also evaluated. Leukotoxic activity was determined using a trypan blue exclusion method. The 530 bp deletion in the promoter region was evaluated by PCR using a PRO primer pair. A. actinomycetemcomitans was detected by culture and directly from crude subgingival biofilm by PCR using specific primers. By culture, A. actinomycetemcomitans was detected in nine (18%) of...

Ano: 2008 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1517-83822008000400011 Prevalence of leukotoxic genotypes of Actinobacillus actinomycetemcomitans in Brazilians with chronic periodontitis BJM Rosalem Junior,Wilson; Andrade,Arnaldo Feitosa Braga de; Colombo,Ana Paula Vieira. Actinobacillus actinomycetemcomitans is considered a major etiologic agent of aggressive periodontitis but this species has also been associated with other forms of periodontal disease. Further, highly leukotoxic strains are related to severity of disease. This investigation determined the prevalence of A. actinomycetemcomitans and the occurrence of the leukotoxin gene 530-bp deletion in Brazilian subjects with chronic periodontitis. Twenty periodontally healthy and 20 chronic periodontitis subjects were selected. Full-mouth clinical examination was carried out at 6 sites/tooth. Subgingival biofilm samples were collected from the 3 deepest sites and 3 healthy sites from periodontitis subjects, as well as from 3 sites of individuals with periodontal health....
