The genome sequence of Bacillus cereus ATCC 10987 reveals metabolic adaptations and a large plasmid related to Bacillus anthracis pXO1 (2004)

Rasko, David A., Ravel, Jacques, Økstad, Ole Andreas, Helgason, Erlendur, Cer, Regina Z., Jiang, Lingxia, ...

We sequenced the complete genome of Bacillus cereus ATCC 10987, a non‐lethal dairy isolate in the same genetic subgroup as Bacillus anthracis. Comparison of the chromosomes demonstrated that...

Replication Mechanism and Sequence Analysis of the Replicon of pAW63, a Conjugative Plasmid from Bacillus thuringiensis

Wilcks, Andrea, Smidt, Lasse, Økstad, Ole Andreas, Kolstø, Anne-Brit, Mahillon, Jacques, Andrup, Lars

A 5.8-kb fragment of the large conjugative plasmid pAW63 from Bacillus thuringiensis subsp. kurstaki HD73 containing all the information for autonomous replication was cloned and sequenced. By...
