WebDec 24, 2024 · One example is daptomycin, a lipopeptide which has a distinct mechanism of action, disrupting multiple aspects of bacterial cell membrane function. It appears to bind to the membrane causes rapid depolarization, resulting in a loss of membrane potential leading to inhibition of protein, DNA and RNA synthesis, which results in bacterial cell death. WebDaptomycin is an alternative option for the treatment of catheter-related bloodstream-infections caused by methicillin-resistant Staphylococcus aureus. This study reports a case of a daptomycin and methicillin-resistant Staphylococcus aureus isolate recovered from the blood of a Brazilian patient undergoing hemodialysis.
