Lineage: Vibrio cholerae; Vibrio; Vibrionaceae; Vibrionales; Proteobacteria; Bacteria

General Information: Vibrio cholerae MJ-1236 is a toxigenic O1 El Tor Inaba strain from Matlab, Bangladesh, 1994 that represents the "Matlab variant" of El Tor. This genus is abundant in marine or freshwater environments such as estuaries, brackish ponds, or coastal areas; regions that provide an important reservoir for the organism in between outbreaks of the disease. Vibrio can affect shellfish, finfish, and other marine animals and a number of species are pathogenic for humans. Vibrio cholerae can colonize the mucosal surface of the small intestines of humans where it will cause cholera, a severe and sudden onset diarrheal disease. One famous outbreak was traced to a contaminated well in London in 1854 by John Snow, and epidemics, which can occur with extreme rapidity, are often associated with conditions of poor sanitation. The disease has a high lethality if left untreated, and millions have died over the centuries. There have been seven major pandemics between 1817 and today. Six were attributed to the classical biotype, while the 7th, which started in 1961, is associated with the El Tor biotype.

Subject: NC_020064:3609844 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.
