Query: NC_016610:1805126 Tannerella forsythia ATCC 43037 chromosome, complete genome
Lineage: Tannerella forsythia; Tannerella; Porphyromonadaceae; Bacteroidales; Bacteroidetes; Bacteria
General Information: This organism is a key agent in the progression of periodontal disease and is involved in bone loss and loss of attachment of teeth. The pathogenic factors involved in this are poorly understood. Unlike other periodontal organism such as Porphyromonas gingivalis and Prevotella intermedia, this organism is difficult to culture and the prevalence of the organism in periodontal disease may be underestimated. This organism is synergistic with Porphyromonas gingivalis, and the presence of both accelerates progression of the disease.
Subject: NC_010741:107370 Treponema pallidum subsp. pallidum SS14, complete genome
Lineage: Treponema pallidum; Treponema; Spirochaetaceae; Spirochaetales; Spirochaetes; Bacteria
General Information: Treponema pallidum subsp. pallidum SS14 was isolated in 1977 from a patient with secondary syphilis. This strain is less susceptible than the Nichols strain for a number of antibiotics. This organisms is divided into subspecies each of which causes a specific disease. This organism is the causative agent of endemic and venereal syphilis. This sexual transmitted disease was first discovered in Europe at the end of the fifteenth century, however, the causative agent was not identified until 1905. At one time syphilis was the third most commonly reported communicable disease in the USA. Syphilis is characterized by multiple clinical stages and long periods of latent, asymptomatic infection. Although effective therapies have been available since the introduction of penicillin, syphilis remains a global health problem.
