The AggAct dtec-qPCR comprises a series of species-specific targeted reagents designed for detection of Aggregatibacter actinomycetemcomitans by using qPCR. Aggregatibacter actinomycetemcomitans (previously Actinobacillus actinomycetemcomitans) is a Gram-negative facultative non-motile rod oral commensal often found in association with localized aggressive periodontitis, although it is also associated with non-oral infections. Its role in periodontitis was first discovered by Danish-born periodontist Jørgen Slots. It is one of the bacteria that might be implicated in destructive periodontal disease. Although it has been found more frequently in localized aggressive periodontitis, prevalence in any population is rather high.
