Aggregatibacter actinomycetemcomitans is a Gram-negative bacillus known to cause periodontitis, skin abscess, osteomyelitis and endocarditis. These 3 species have recently been transferred to the new genusAggregatibacter within the family Pasteurellaceae (45). Trying an antiseptic mouthwash to eliminate bacteria that live between the teeth. Clinical experience suggests that treatment of endocarditis with penicillin and gentamicin usually is successful. Aggregatibacter aphrophilus was first isolated in 1940 from a case of infective endocarditis. In a healthy mouth, the balance of different bacteria keeps AA in check. In 2006, the former Actinobacillus actinomycetemcomitans, Hemophilus aphrophilus, and Haemophilus segnis were reclassified into the same genus, Aggregatibacter [3].

Aggregatibacter actinomycetemcomitans is a Gram-negative bacterium that colonizes the human oral cavity and is the causative agent for localized aggressive periodontitis (LAP), an aggressive form of periodontal disease that occurs in adolescents.A. A single treatment of the clinically achievable concentration of 10 mg/L doxycycline to sparse A. actinomycetemcomitans biofilms in the flow chamber model resulted in significant decreases in biofilm thickness, biovolume, and cell viability. systemic azithromycin (AZM) in adjunct to nonsurgical periodontal therapy (NSPT; or scaling root planing - SRP) in treatment of Aggregatibacter actinomycetemcomitans associated periodontitis (AAAP). Actinobacillus actinomycetemcomitanswas separated from periodontitis patients and grown in a specific condition to characterize energy metabolism of A. actinomycetemcomitans. All rights reserved. The JCDR article describes how AA is particularly associated with periodontitis (gum disease) in young individuals, known more specifically as Localized Juvenile Periodontitis (LJP). This article is intended to promote understanding of and knowledge about general oral health topics. 2005;113:225–8. 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. Burgess DK, Huang H, Harrison P, Kompotiati T, Aukhil I, Shaddox LM. Several bacteria responsible for periodontal disease, including Porphyromonas gingivalis, Campylobacter rectus, Fusobacterium nucleatum and Aggregatibacter actinomycetemcomitans, have been identified (Harvey, 2017). Here's how these bacteria develop and affect our mouths, and what you can do to keep them under control. LJP is typically genetic or hereditary and mostly affects young adults between 25 and 30 years old. 2020 Jun;35(3):85-105. doi: 10.1111/omi.12284. 2010;43:491–7.

Oral Dis. Low concentrations of antibiotics enhanced biofilm formation. This bacterium was first isolated by Klinger 81 from a cervicofacial actinomycotic lesion in 1912 and was named Bacterium actinomycetemcomitans. The aims of this study were to test in vitro the sensitivity of A. actinomycetemcomitans JP2 during planktonic and biofilm growth to doxycycline and to the combination of metronidazole and amoxicillin, which are two antibiotic protocols commonly used in clinical practice. Two in vitro biofilm models were used to test the effects of the antibiotics: a static 96-well plate assay was used to investigate the effect of these antibiotics on biofilm formation whilst a flow chamber model was used to examine the effect on established biofilms. J Periodontol. 2009;36:739–49. Early diagnosis in any form of periodontitis is critical to ensuring that the disease doesn't worsen.
