Figure 5From: The alkylation response protein AidB is localized at the new poles and constriction sites in Brucella abortusMorphological defect of the B. abortus aidB overexpressing strain. Differential interference contrast (DIC) images were taken with bacteria of the aidB (aidB+++), acaD1 (acaD1+++) and acaD2 (acaD2+++) overexpression strains, the aidB disruption strain, and the wild-type strain with or without the control pBBR1MCS plasmid [32], without insert. Two panels are shown for the aidB overexpression strain, the only strain displaying a morphological defect during stationary culture phase. The morphological defects are multiple, with multipolar bacteria (M), Y-shaped cells (y), swollen cells (s) and some minicells (m).Back to article page
