#MicrobiologyMonday: Staphylococcus aureus divides by building a septum and then splitting into 2 daughter cells. But how is septum formation coordinated with cell scission? Research in #mBio suggests cell wall mechanical stress could play a role: asm.social/2Eq
Mechanical stress in the S. aureus cell wall during the cell cycle. (A) As the cell cycle progresses, stress at the equator decreases due to growth of the septum while the stress remains unchanged at the pole. The stress distributions shown here were calculated for MSSA with cell volume 1.22 µm3, thickness 20 nm, turgor pressure 2 MPa, and septum relative stiffness 1.2. (B) Graphical representation of the changes in circumferential stress at the cell pole and equator as septum synthesis progresses. Here, septum progression is defined as (a − b)/a, where a is the cell radius and b is the septum aperture size, which decreases as the septum is formed (note that a and b are defined for the unpressurized cell; see Supplementary Information, Section II).

Chromosome segregation dynamics during the cell cycle of Staphylococcus aureus - Nature Communications
Our understanding of chromosome organization and dynamics in spherical bacteria, such as Staphylococcus aureus, remains limited. Here, the authors show that chromosome replication and cell division cycles are not synchronized in S. aureus, with cells exhibiting two segregated origins of replication at the start of the cell cycle.
