Query: NC_006348:2738425 Burkholderia mallei ATCC 23344 chromosome 1, complete sequence
Lineage: Burkholderia mallei; Burkholderia; Burkholderiaceae; Burkholderiales; Proteobacteria; Bacteria
General Information: This type strain came from a Chinese patient in Burma who had glanders in 1944. Causes glanders in horses. This organism is rarely associated with human infection, and is more commonly seen in domesticated animals such as horses, donkeys, and mules where it causes glanders, a disease first described by Aristotle. The pathogen is host-adapted and is not found in the environment outside of its host. Rapid-onset pneumonia, bacteremia (spread of the organism through the blood), pustules, and death are common outcomes during infection. No vaccine exists for this potentially dangerous organism.
Subject: NC_008044:1401814 Silicibacter sp. TM1040, complete genome
Lineage: Ruegeria; Ruegeria; Rhodobacteraceae; Rhodobacterales; Proteobacteria; Bacteria
General Information: This strain was isolated from a culture of the dinoflagellate Pfiesteria piscicida CCMP1830 which has been implicated in many large scale algal blooms resulting in increased mortality in fish. The bacteria are attached to the surface of the dinoflagellate and in some ways allow the dinoflagellate to grow as those lacking the bacteria die off. The bacterium also chemotaxes towards the dinoflagellate product DMSP (dimethylsulfoniopropionate) and metabolizes it. DMSP is a major source of sulfur in marine ecosystems and plays a role in the sulfur biogeochemical cycle. The implication is a tight association between these important dinoflagellates and this marine bacterium.
