Query: NC_007798:586500 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_008819:1531187 Prochlorococcus marinus str. NATL1A, complete genome
Lineage: Prochlorococcus marinus; Prochlorococcus; Prochlorococcaceae; Prochlorales; Cyanobacteria; Bacteria
General Information: This strain was collected from the north Atlantic Ocean at a depth of 30 m and was isolated by filter fractionation. This strain belongs to the 'low light-adapted' ecotype, clade I, and has a high Chl b/a2 ratio. Marine cyanobacterium. This non-motile bacterium is a free-living marine organism that is one of the most abundant, as well as the smallest, on earth, and contributes heavily to carbon cycling in the marine environment. This cyanobacterium grows in areas of nitrogen and phosphorus limitation and is unique in that it utilizes divinyl chlorophyll a/b proteins as light-harvesting systems instead of phycobiliproteins. These pigments allow harvesting of light energy from blue wavelengths at low light intensity.
