New PhD Opportunity :

To kill and cure: Understanding antibiotic action to enhance activity

Antibiotics are at the core of modern medicine, but they are under threat due to the spread of resistance. Antibiotics either kill (bactericidal) or stop bacteria growing (bacteriostatic). Extraordinarily we still do not know why only some antibiotics kill or what mechanism(s) lead to death.

New publication:

Evolution of Beta-Lactam resistance in MRSA

The model system constructed in this work mimics the naturally occurring MRSA, to understand the underpinning mechanisms of S. aureus which develop high-level resistance. Our study reveals a novel effect of mecA acquisition and compensatory mutations on central metabolism and sheds light on potential pathways essential for high-level resistance.

You can read our new Publication Evolution of Beta-lactam resistance in MRSA in PLOS Pathogens.

New publication:

The architecture of the Gram-positive bacterial cell wall

New research, published in Nature, revealed a new and unexpected structure of the outer bacterial layers of the bacterium Staphylococcus aureus. Click here to read

Scientists from the Hobbs and Foster Labs at the University of Sheffield have produced the first high-resolution images of the structure of the cell wall of bacteria using Atomic Force Microscopy (AFM), in a study that could further understanding of antimicrobial resistance.

The findings set a new framework for understanding how bacteria grow and how antibiotics work, overturning previous theories about the structure of the outer bacterial layers.
