Abstract:
Staphylococcus aureus is the most common cause of hospital-acquired bacteremia. Due to emergence of antibiotic-resistant strains, these infections present a serious public health threat. In this study, to develop a broadly protective vaccine, we tested whether immune responses induced by several proteins associated with S. aureus toxicity could protect mice from lethal challenge with human clinical S. aureus isolate USA300. We found that the surface protein A (SasA) of S. aureus could protect mice from lethal challenge of the bacteria.

Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
