Special Issue Information

Dear Colleagues,

This Special Issue will focus upon the recent advances in staphylococcal biology, aiming to elucidate its complex mechanisms of pathogenesis. New data on cell wall and surface structures (teichoic acids, lipids, protein A, TcaA, polysaccharide intercellular adhesin) and extra-cellular enzymes (DNases, hemolysins) have demonstrated the wide array of mechanisms utilized by staphylococci to cause persistent infections. Data on how the metabolism impacts antibiotic resistance and macrophage activation (host–bacterial interactions) reveal an extremely dynamic interplay between the host and pathogen.  A prophage that enhances persistent bacteremia via novel mechanisms has been identified. Finally, the complex immunological responses to S. aureus (allergic response; persistence due to IL-10; hyper-responsiveness in humanized mice; non-protective imprinting) enable a deeper understanding of the host–pathogen interactions.  All of this complexity helps to clarify why the development of a staphylococcal vaccine is so challenging.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Antibiotics is an international peer-reviewed open access monthly journal published by MDPI.

Vaccination arguably remains the only long-term strategy to limit the spread of S. aureus infections and its related antibiotic resistance. To date, however, all staphylococcal vaccines tested in clinical trials have failed. In this review, we propose that the failure of S. aureus vaccines is intricately linked to prior host exposure to S. aureus and the pathogen’s capacity to evade adaptive immune defenses. We suggest that non-protective immune imprints created by previous exposure to S. aureus are preferentially recalled by SA vaccines, and IL-10 induced by S. aureus plays a unique role in shaping these non-protective anti-staphylococcal immune responses. We discuss how S. aureus modifies the host immune landscape, which thereby necessitates alternative approaches to develop successful staphylococcal vaccines. Full article
