Adaptive responses in Bacillus cereus group bacteria : microarray comparisons and follow-up studies

Abstract

Through activation of adaptive mechanisms, members of the Bacillus cereus group are able to exploit a vairety of biological niches. In this work, microarray studies and other techniques were used to study some of these adaptive responses. The effects of the transition state regulators PlcR and NprR were studied by the use of deletion mutants of their respective genes. Microarray studies were also used to compare swarming and non-swarming Bacillus cereus. Finally, microarrays and a variety of other techniques were used to describe and possibly find a cause for morphological differences between three variants of Bacillus cereus ATCC 14579.
