Query: NC_016610:3297080 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_008599:596849 Campylobacter fetus subsp. fetus 82-40, complete genome
Lineage: Campylobacter fetus; Campylobacter; Campylobacteraceae; Campylobacterales; Proteobacteria; Bacteria
General Information: This strain (82-40) was isolated from the blood of a human patient who was having a renal transplant and is the best characterized isolate of this species.. The ratio of bloodstream infection to diarrheal illnesses for C. fetus is nearly 400-fold higher than for C. jejuni, indicating its marked propensity for invasive disease compared to C. jejuni. Causes infertility, infectious abortions in cattle, opportunistic human pathogen. This organism causes infertlity and infectious abortions in domesticated sheep, goats and cattle. It is an opportunistic pathogen in humans which can severely affect immunocompromised patients. Initially the bacterium can cause gastroenteritis, and then spread systemically throughout the blood (bacteremia) and cause septicemia, meningitis, and other systemic infections. This layer is essential for host colonization, and prevents complemented-mediated immune responses by inhibiting complement C3b binding.
