Burkholderia mallei (B. mallei), strain China 7 (NBL 7) was isolated from postmortem cultures of knee fluid, skin pustules, and blood of a Chinese soldier who died in Burma in 1944 from a glanders-melioidosis type of infection. B. mallei, strain China 7 (NBL 7) was deposited to the ATCC ® in 1967 by George A. Hottle of the Naval Biological Laboratory, University of California at Berkeley and accessioned as ATCC ® 23344™. NR-23 was produced directly from a lot of ATCC ® 23344™.

Genome variability upon passage has been reported to be a feature of B. mallei, strain China 7. Two other preparations of B. mallei, strain China 7 are available from BEI Resources. NR-4071 was derived from a lot of ATCC ® 23344™ via several passages by different individuals prior to deposit to BEI Resources. NR-36128 was accessioned by the National Collection of Type Cultures (NCTC) in 2007 and deposited to BEI Resources by the Health Protection Agency, United Kingdom (Public Health England). The passage history of the NCTC version of strain China 7 is not known. The complete genome sequence from a preparation of B. mallei, strain China 7 is available (GenBank: CP000010 and CP000011).

Each vial contains approximately 1 mL of bacterial culture in Tryptic Soy broth supplemented with 10% glycerol.

Note: If homogeneity is required for your intended use, please purify prior to initiating work.
