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_010554:1008444 Proteus mirabilis HI4320, complete genome

Lineage: Proteus mirabilis; Proteus; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria

General Information: Proteus mirabilis is a tetracycline resistant human urinary tract isolate. This bacterium is part of the normal gut flora of a healthy individual, but is also an opportunistic pathogen. Flagellar movement allows this organism to travel through the urinary tract into the bladder and kidney where it may cause infection or stones. Cell death is caused by hemolysin, a pore-forming toxin which disrupts osmotic balance across the host cell membrane. This species is inherently resistant to nitrofuran and tetracycline, and some strains have recently become resistant to ampicillin and trimethoprin.
