Query: NC_013416:1783349 Aggregatibacter actinomycetemcomitans D11S-1, complete genome Lineage: Aggregatibacter actinomycetemcomitans; Aggregatibacter; Pasteurellaceae; Pasteurellales; Proteobacteria; Bacteria General Information: Aggregatibacter actinomycetemcomitans D11S-1 was recovered from a subject with aggressive periodontitis. Aggregatibacter actinomycetemcomitans, previously Actinobacillus actinomycetemcomitans typically resides in the oral cavity of humans and animals and can cause a number of diseases. The bacterium, along with 3 other organisms, is the main culprit in periodontis, which results in devastation to the bone supporting the teeth. Adherence to oral surfaces is controlled through the tad (tight adherence) locus, which may express proteins that are involved in type IV secretion.

General Information: This strain (ATCC BAA-672) is a virulent blackleg isolated from the stem of a potato plant. Causative agent for blackleg and soft rot disease in potatoes. Formerly Erwinia, these organisms are plant-specific pathogens that invade the vascular systems of plants. Both Pectobacterium chrysanthemia and Pectobacterium carotovora cause soft-rot diseases of various plant hosts through degradation of the plant cell walls. Pectobacterium colonize the intercellular spaces of plant cells and deliver potent effector molecules (Avr - avirulence) through a type III secretion system (Hrp - hypersensitive response and pathogenicity). Avr proteins control host-bacterium interactions, including host range. Expression of the plant cell-wall-degrading enzymes is controlled through a quorum-sensing mechanism that quantifies the number of Pectobacterium bacteria through measurement of the concentration of small molecules (acyl homoserine lactones) produced by Pectobacterium. Pectobacterium atrosepticum is an environmentally widespread organism that causes blackleg and soft rot disease in potatoes. This organism produces pectolytic enzymes that destroy plant tissue and allow the bacteria to spread.
