Abstract
We report the case of a patient with infective endocarditis on a prosthetic aortic valve due to Staphylococcus epidermidis, not a candidate for prosthetic replacement surgery. After three months of supressive treatment with dalbavancin, fever reappears, with growth of S. epidermidis. Susceptibility testing showed new-onset resistance to dalbavancin, with a mutation in walK gene.
