Identification of Fur-regulated genes in Actinobacillus actinomycetemcomitans.
Actinobacillus actinomycetemcomitans is an oral pathogen that causes aggressive periodontitis as well as sometimes life-threatening, extra-oral infections. Iron regulation is thought to be important in the pathogenesis of A. actinomycetemcomitans infections and, consistent with this hypothesis, the fur gene has recently been identified and characterized in A. actinomycetemcomitans. In this stud...
متن کاملIdentification of Actinobacillus actinomycetemcomitans serotypes by multiplex PCR.
Oligonucleotide primers specific for gene clusters involved in the biosynthesis of serotype-specific polysaccharide antigens were designed to identify Actinobacillus actinomycetemcomitans serotypes a to e using the multiplex PCR. This method may be useful for serotype-specific genotyping rapidly and directly from clinical samples containing various organisms.
متن کاملDetection and strain identification of Actinobacillus actinomycetemcomitans by nested PCR.
By using PCR, Actinobacillus actinomycetemcomitans strains were identified directly from plaque samples without the need to isolate or culture bacteria. DNA fragments were generated by a nested, two-step PCR amplification of the ribosomal spacer region between the 16S and 23S rRNA genes. For the first amplification, primers homologous to sequences common to all bacterial species were used. This...
متن کاملCharacterization of serologically nontypeable Actinobacillus actinomycetemcomitans isolates.
Our previous studies have shown that Actinobacillus actinomycetemcomitans isolates of a given arbitrarily primed PCR (AP-PCR) genotype belong to the same serotype (of serotypes a through e). In the present study we investigated whether the AP-PCR genotypes of nonserotypeable A. actinomycetemcomitans isolates match those of the serotypeable isolates. The isolates were additionally characterized ...
متن کاملSecretion of RTX leukotoxin by Actinobacillus actinomycetemcomitans.
Actinobacillus actinomycetemcomitans, the etiologic agent for localized juvenile periodontitis and certain other human infections, such as endocarditis, expresses a leukotoxin that acts on polymorphonuclear leukocytes and macrophages. Leukotoxin is a member of the highly conserved repeat toxin (RTX) family of bacterial toxins expressed by a variety of pathogenic bacteria. While the RTX toxins o...
