Yersinia pestis (Y. pestis), strain A1122 (biovar Orientalis) was isolated from a California ground squirrel (Spermophilus beecheyi) in California, USA, 1939.

Y. pestis,, strain A1122 is known to contain the pMT1 and the pPCP1 plasmids, but lacks the pCD1 plasmid that is essential for virulence as well as the unstable pgm locus.

The presence of the pMT1 and pPCP1 plasmids in NR-636 has been confirmed by PCR amplification of plasmid-specific sequences from extracted DNA.

Each vial contains approximately 0.5 mL of bacterial culture in 0.5X broth supplemented with 10% glycerol.

Additional information and tools are available at PATRIC (Pathosystems Resource Integration Center).
