Actinic keratoses (AK) are premalignant lesions common on photo-damaged skin that, over time, can progress to squamous cell carcinoma (SCC). A high bacterial load of Staphylococcus aureus is associated with AK and SCC but it is unknown whether this has a direct impact on skin cancer development. To ...

This investigation reports a differential proteomic analysis of the secretome of six S. aureus strains belonging to two genotypes with opposite within-herd prevalence, GTB (high) and GTS (low), corresponding to sequence types (ST) 8 and 398, respectively. Total proteins released in the growth medium...

The secretome of the Staphylococcus aureus includes specific pathway-exported proteins, as well as cytoplasmic proteins with unknown mechanisms of secretion. As one component of the S. aureus secretome, extracellular membrane vesicles (MVs) are also comprised of secreted and cytoplasmic proteins. Ho...

To combat methicillin-resistant Staphylococcus aureus (MRSA) infections novel drugs are desperately needed. From a screen, we found that the anti-cancer drug sorafenib effectively kills MRSA strains. By synthetic variation of key structural features, we identified a potent analog, PK150, exhibiting ...

Studies on S. aureus sub-populations revealed that genomes are well conserved between isolates from the same lineages despite geographic, temporal and selective diversity. However, variation of hundreds of genes can occur between isolates from different lineages and these genes could be involved in ...

Staphylococcus aureus represents an opportunistic pathogen which utilizes elaborate quorum sensing mechanisms to precisely control the expression and secretion of virulence factors. Previous studies indicated a role of the ClpXP proteolytic system in controlling pathogenesis. While detailed transcri...

The Gram-positive pathogenic bacterium Staphylococcus aureus permanently colonizes the nasal mucosa in about 30% of the healthy population. However, as an opportunistic pathogen, S. aureus can also cause a variety of diseases, the treatment of which is becoming increasingly difficult due to antibiot...

To combat methicillin-resistant Staphylococcus aureus (MRSA) infections novel drugs addressing unprecedented and resistance-free targets are desperately needed. From a screen of human kinase inhibitors, we find that the anti-cancer drug sorafenib effectively kills MRSA strains. By dissection of the ...

Surface-located and secreted virulence factors of the Gram-positive bacterial pathogen Staphylococcus aureus are key drivers for infection of the human host. Proteolytic enzymes may contribute to virulence by breaking primary barriers and host immune defenses. Therefore, the objective of our present...
