Query: NC_007798:260324 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_007712:1182518 Sodalis glossinidius str. 'morsitans', complete genome
Lineage: Sodalis glossinidius; Sodalis; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: Sodalis glossinidius is known exclusively in endosymbiosis with tsetse flies. It is maternally transmitted, and is one of the few bacterial endosymbionts of insects that can be cultured successfully in vitro. Genome data reveals a high proportion of pseudogenes in this species, many of which were, in their functional state, involved in defense or transport of carbohydrates and inorganic ions. This suggests a degenerative adaptation to the immunity and restricted nutritional status of the host.
