Query: NC_018000:3009864 Sinorhizobium fredii USDA 257 chromosome, complete genome
Lineage: Sinorhizobium fredii; Sinorhizobium; Rhizobiaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: This organism, much like other Rhizobia, forms a symbiotic relationship with a leguminous plant, such as soybean, cowpea or pigeon pea. Expression of nodulation genes results in production of a nodulation signal which the plant cell recognizes inducing root nodule formation. The plant cell provides carbon compounds for the bacterium to grow on.
Subject: NC_008836:1072721 Burkholderia mallei NCTC 10229 chromosome II, complete sequence
Lineage: Burkholderia mallei; Burkholderia; Burkholderiaceae; Burkholderiales; Proteobacteria; Bacteria
General Information: 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.
