Query: NC_007963:2555012 Chromohalobacter salexigens DSM 3043, complete genome
Lineage: Chromohalobacter salexigens; Chromohalobacter; Halomonadaceae; Oceanospirillales; Proteobacteria; Bacteria
General Information: Chromohalobacter salexigens DSM 3043 was first isolated from a solar salt facility on Bonaire Island, Netherlands Antilles. A moderate halophile which can grow on a variety of salts. This bacterium is a moderate halophile, yet does not require high concentrations of sodium chloride. The salt requirements of this organism can be met by ions of other salts, such as potassium, rubidium, ammonium, bromide. Several plasmids have been isolated from this organism. Plasmid pMH1 contains genes for resistance to kanamycin, neomycin, and tetracycline. A smaller plasmid, pHE1, which does not code for antibiotic resistance genes, has also been isolated.
Subject: NC_010159:172469 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.
