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_009901:2915939 Shewanella pealeana ATCC 700345, complete genome
Lineage: Shewanella pealeana; Shewanella; Shewanellaceae; Alteromonadales; Proteobacteria; Bacteria
General Information: This species was isolated from a microbial community colonizing the accessory nidamental gland of the squid Loligo peali (Atlantic squid) for their capacity to respire on sulfur. It was placed in the Shewanella genus based on physiological and biochemical characteristics and 16S rRNA sequence analysis. Shewanella are ubiquitous in marine environment and play very important role in global carbon and nitrogen cycle. The present strain is moderately halophilic, requiring sodium ions for growth. Shewanella are facultatively anaerobic, Gram-negative bacteria, motile by polar flagella, rod-like, and generally associated with aquatic or marine environments.
