This genus contains microbial species that can reside in the human gastrointestinal tract. [PMC 4262072] Aggregatibacter actinomycetemcomitans (previously Actinobacillus actinomycetemcomitans) is a Gram-negative, facultative nonmotile, rod-shaped oral commensal often found in association with localized aggressive periodontitis, a severe infection of the periodontium, although it is also associated with nonoral infections. Its role in periodontitis was first discovered by Danish-born periodontist Jørgen Slots, a professor of dentistry and microbiology at the University of Southern California School of Dentistry.
'Bacterium actinomycetem comitans' was described by Klinger (1912) as coccobacillary bacteria isolated together with Actinomyces from actinomycotic lesions of man. It was reclassified as Actinobacillus actinomycetemcomitans by Topley & Wilson (1929) and as Haemophilus actinomycetemcomitans by Potts et al. (1985). The species has attracted attention because of its association with localized aggressive periodontitis.
