As a result of recent experiments in my laboratory, I wish to comment on the report of Han et al., 2011. Specifically, members of my laboratory have recently discovered critical errors in strain PXO99Δax21 used in the reported work. Because key parts of the work depend on the integrity of strain PXO99Δax21, we are now repeating all of the experiments using newly generated and validated strains. We will report the outcome of each of these experiments on this page. We note that much of the work has been independently validated in other laboratories (see McCarthy et al., 2011, J Bacteriology 193:6375-6378).
