Multiple classes of bactericidal antibiotics cause DNA double strand breaks in Staphylococcus aureus

R. S. Clarke, K. P. Ha, A. M. Edwards

This study shows that multiple antibiotic classes induce DNA double strand breaks in Staphylococcus aureus, which are repaired by the RexAB complex, enhancing bacterial survival.

Staphylococcal DNA repair is required for infection

K. P. Ha, R. S. Clarke, G.-L. Kim, J. L. Brittan, J. E. Rowley, D. Mavridou, D. Parker, T. B. Clarke, A. H. Nobbs, A. M. Edwards

This study identifies DNA repair mechanisms in Staphylococcus aureus essential for survival during infection, showing that host immune cells induce DNA damage repaired by RexAB.

RexAB is essential for the mutagenic repair of Staphylococcus aureus DNA damage caused by co-trimoxazole

R. S. Clarke, M. S. Bruderer, K. P. Ha, A. M. Edwards

This study shows that co-trimoxazole causes DNA damage in S. aureus through thymidine limitation and oxidative stress, which is repaired by the RexAB complex, leading to mutagenesis and antibiotic resistance.

The electron transport chain sensitises Staphylococcus aureus and Enterococcus faecalis to the oxidative burst

K. L. Painter, A. Hall, K. P. Ha, A. M. Edwards

The paper shows that loss of the electron transport chain in Staphylococcus aureus and Enterococcus faecalis SCVs increases resistance to the oxidative burst in human blood.
