Query: NC_010159:741819 Yersinia pestis Angola, complete genome Lineage: Yersinia pestis; Yersinia; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria General Information: This strain was isolated prior to 1985 and belongs to the antiqua biovar. It can ferment rhamnonse and melibiose which is a property usually associated with Yersinia pseudotuberculosis. Strain Angola belongs to a group of atypical Yersinia pestis strains with genotypic similarities that are intermediate between Y. pestis and Y. pseudotuberuclosis strains. Genotypic studies indicate that strain Angola is the oldest Y. pestis strain analyzed to date. It carries three plasmids that are similar to other Y. pestis plasmids but have aberrant sizes. The critical virulence factor, the V antigen, is different than that encoded by typical strains of Y. pestis and there is a deletion that affects the F1 operon. Strain Angola has been shown to be virulent by aerosol in mice.

General Information: This strain was isolated from sediment contaminated with cis-dichloroethane (cDCE), a common pollutant resulting from widespread manufacture and use of industrial solvents. This bacterium is the only known organism capable of using cDCE as a sole carbon and energy source. The ability of this strain to convert ethene to epoxyethane suggests that the first step in the cDCE biodegradation pathway is the oxidation of cDCE to an epoxide compound. Bacteria that are able to grow on cDCE are rare, and have only been found in very few highly selective artificial environments. The discovery of this bacteria may provide a low cost, self-sustaining bioremediation method in areas where cDCE is a problem contaminant.
