Query: NC_007798:703922 Neorickettsia sennetsu str. Miyayama, complete genome
Lineage: Neorickettsia sennetsu; Neorickettsia; Anaplasmataceae; Rickettsiales; Proteobacteria; Bacteria
General Information: This organism was first described in 1953 in Japan as causing Sennetsu fever. Causes an infectious mononucleosis-like disease. Like other Ehrlichia, this organism is an obligate intracellular pathogen. It can be transmitted from fish flukes (trematodes) to humans, and was one of the first Ehrlichia that was found to cause a human-specific illness.
Subject: NC_002678:2739829 Mesorhizobium loti MAFF303099, complete genome
Lineage: Mesorhizobium loti; Mesorhizobium; Phyllobacteriaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: Plant symbiont bacterium. This organism contains a symbiosis island that is responsible for symbiotic relationships with plants (lotus) which is similar to what is observed with other Rhizobia that form similar relationships with legumes. The bacterium enters root nodules and performs nitrogen-fixation for the plant cell while being provided with a protective environment to grow in. Nitrogen fixation and root nodule formation genes are carried on a symbiosis island.
