Query: NC_003919:2435058 Xanthomonas axonopodis pv. citri str. 306, complete genome
Lineage: Xanthomonas citri; Xanthomonas; Xanthomonadaceae; Xanthomonadales; Proteobacteria; Bacteria
General Information: This organism is the causal agent of citrus canker, a bacterial infection originating from southeast Asia which now occurs worldwide. Primarily a pathogen of plants in the Citrus genus, the disease is sometimes also found in other members of the Rutaceae. The bacterium survives in leaf, shoot and fruit lesions that develop during the spring, and which also cause secondary infections. During warm, wet weather in spring and early summer, the bacterium oozes out of overwintering lesions and infects new growth via the stomal pores or wounds. The bacterium may also survive for various periods of time in the soil or associated with other hosts.
Subject: NC_010159:2128157 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.
