Isolated from a periodontal pocket of a 76 year old woman. Bacillus cereus AH820

Bacillus cereus AH820. This strain was isolated in October 1995 in Akershus, Norway, from the periodontal pocket of a 76 year old female patient with marginal periodontitis and was further analyzed by Helgason et al. (2000 J Clin Microbiol. 38, 1615-1622). B. cereus AH820 resides very close to the B. anthracis cluster using MLST analyses, and is 100% identical in all 7 loci to 3 other periodontal B. cereus isolates, suggesting that these human pathogens form a distinct clade within the group. Sequence was obtained from three libraries - a fosmid library (33-39 kb; 48,035 reads), a medium insert library (10-12 kb; 11,689 reads), and a small insert library (3-5 kb; 12;650 reads).
