Hope for a vaccination against Staphylococcus areus infections?
Staphylococcus aureus (S. aureus) ranks among the globally most important causes of infections in humans and is considered a dreaded hospital pathogen. Active and passive immunisation against multi-resistant strains is seen as a potentially valuable alternative to antibiotic therapy. However, all vaccine candidates so far have been clinically unsuccessful. With an epitope-based immunisation, scientists at Cologne University Hospital and the German Center for Infection Research (DZIF) have now described a new vaccination strategy against S. aureus in the Nature Partner Journal NPJ VACCINES.

Trial shows using two drugs not better than one when treating MRSA blood infections
Researchers attempting to improve the treatment for methicillin-resistant Staphylococcus aureus (MRSA) blood infections have discovered the combination of two antibiotics was no better than one, and led to more adverse effects. In what is the biggest trial of MRSA bloodstream infections to date, (352 participants from Australia, Singapore, New Zealand and Israel), the CAMERA2 clinical trial, researchers were surprised to see the drug combination wasn't as effective as anticipated. (2020-02-11)
