Background: Leukotoxin (Ltx) expressed by Aggregatibacter actinomycetemcomitans is a powerful exotoxin, which can cause imbalance in host response. This article is intended to promote understanding of and knowledge about general oral health topics. Several bacteria responsible for periodontal disease, including Porphyromonas gingivalis, Campylobacter rectus, Fusobacterium nucleatum and Aggregatibacter actinomycetemcomitans, have been identified (Harvey, 2017). Results: However, when AA is given the opportunity to grow, there is a higher risk of developing gum disease. Your dental professional will assess you thoroughly to decide which option is best for you or may refer you to a gum specialist known as a periodontologist. It has previously been shown that the presence of Aggregatibacter actinomycetemcomitans in subgingival plaque is significantly associated with increased risk for clinical attachment loss. 2009, 47(7):2018. Antibiotic therapy using amoxicillin/clavulanic acid, ampicillin, ampicillin/sulbactam, ceftriaxone, clindamycin, cefotaxime, or levofloxacin was successful in all patients. © YYYY Colgate-Palmolive Company. Treatment may include a number of deep cleaning methods, such as scaling and root planing, as the Mayo Clinic explains. Low concentrations of antibiotics enhanced biofilm formation. Conclusion: The diagnosis of invasive A. actinomycetemcomitans infection was delayed due to the indolent clinical course, non-specific presentation and slow growth of the organism. Ask the Colgate Chatbot! Aggregatibacter actinomycetemcomitans formely known as Actinobacillus actinomycetemcomitans is a known part of the normal oral flora. Participants were treated during the first 4 months by receiving (i) scaling and root planing, (ii) systemic antibiotic therapy, and (iii) periodontal surgery. If this disease is left untreated in a younger patient, it can lead to destruction of the tooth tissues, hence why AA is known as a tooth killer.

Reconsidering the Use of Minocycline in the Preliminary Treatment Regime of Rheumatoid Arthritis. Despite its name, it is not commonly known to clinicians that A.actinomycetemcomitans is classically found as part of a polymicrobial infection with Actinomyces spp. The minimal inhibitory concentrations (MIC) of the most commonly used antibiotics in periodontal therapy (amoxicillin, metronidazole, azithromycin, and doxycycline) or in severe body infections (amoxicillin/clavulanic acid, clindamycin, ertapenem, and moxifloxacin) were determined. Aggregatibacter actinomycetemcomitans (previously Actinobacillus actinomycetemcomitans) is a Gram-negative, facultative anaerobe, nonmotile bacterium that is often found in association with localized aggressive periodontitis, a severe infection of the periodontium.
