Query: NC_020064:2921809 Serratia marcescens FGI94, complete genome
Lineage: Serratia marcescens; Serratia; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: This organism was discovered in 1819 by Bizio who named the organism after the Italian physicist Serrati. It was considered a nonpathogenic organism until late in the 20th century, although pathogenicity was noted as early as 1913. Serratia marcescens is an opportunistic human pathogen that is increasingly associated with life-threatening hospital-acquired infections. It is an environmental organism that has a broad host range, and is capable of infecting vertebrates and invertebrates, as well as plants. In humans, Serratia marcescens can cause meningitis (inflammation of the membrane surrounding the brain and spinal cord), endocarditis (inflammation of heart muscle) and pyelonephritis (inflammation of the kidneys). Many strains are resistant to multiple antibiotics. Environmental isolates are noted by production of the red pigment prodigiosin.
Subject: NC_011004:5283648 Rhodopseudomonas palustris TIE-1, complete genome
Lineage: Rhodopseudomonas palustris; Rhodopseudomonas; Bradyrhizobiaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: This strain was isolated from an iron-rich microbial mat from School Street Marsh in Woods Hole, MA, USA. It grows photoautotrophically with Fe(II), H2, or thiosulfate as the electron donor, photoheterotrophically with a variety of organic carbon sources and chemoheterotrophically in the dark. This organism has a diverse metabolism and is capable of growth using light, inorganic, or organic compounds as energy sources and carbon dioxide or organic compounds as carbon sources. Commonly found in soil and water environments this bacterium is also capable of degrading a wide range of toxic organic compounds, and may be of use in bioremediation of polluted sites. The bacterium undergoes differentiation to produce a stalked nonmotile cell and a motile flagellated cell. In the presence of light, this bacterium produces a number of intracellular membranous vesicles to house the photosynthetic reaction centers.
