Lineage: Hahella chejuensis; Hahella; Hahellaceae; Oceanospirillales; Proteobacteria; Bacteria
General Information: This organism was isolated from marine sediment from Cheju Island, Republic of Korea. Hahella chejuensis is a slight halophile with an optimum salinity of 2%. This organism produces a large amount of exopolysaccharide, which has potential as an emulsification agent.
Subject: NC_020211:1621000 Serratia marcescens WW4, 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.
