Clindamycin is also indicated in the treatment of serious infections due to susceptible strains of ... staphylococci Staphylococci: Serious respiratory tract infections; serious skin and soft tissue infections. Bacteriologic studies should be performed to determine the causative organisms and their susceptibility to clindamycin
The oral antibiotic of choice for bacteremia caused by Staphylococcus (Staph) species is clindamycin (PO), but its use should be reserved for cases where the causative organisms are susceptible to clindamycin, as determined by bacteriologic studies 1.
From the Research
The oral antibiotic of choice for Staphylococcus bacteremia is cefazolin or an antistaphylococcal penicillin for methicillin-sensitive Staphylococcus aureus (MSSA), and trimethoprim-sulfamethoxazole (TMP-SMX) or linezolid for methicillin-resistant Staphylococcus aureus (MRSA). However, it's crucial to understand that bacteremia (bacteria in the bloodstream) typically requires initial intravenous antibiotic therapy before transitioning to oral antibiotics. For MSSA, the typical oral step-down therapy would be cefazolin or an antistaphylococcal penicillin, as suggested by the most recent study 2. For MRSA, options include TMP-SMX (1-2 double-strength tablets twice daily) or linezolid 600 mg twice daily.
Treatment duration for uncomplicated Staphylococcus bacteremia is generally 14 days total (IV plus oral), while complicated cases may require 4-6 weeks or longer, as indicated by the study 2. Oral therapy should only be considered after clinical improvement, clearance of bacteremia with negative blood cultures, and source control. The choice between these antibiotics depends on the specific Staphylococcus species, antibiotic susceptibility testing, patient allergies, and comorbidities.
Some key points to consider in the management of Staphylococcus bacteremia include:
- Initial treatment with vancomycin or daptomycin for MRSA, as recommended by the study 2
- Use of cefazolin or antistaphylococcal penicillins for MSSA, as suggested by the study 2
- Importance of source control, including removal of infected devices and drainage of abscesses, as emphasized by the study 2
- Need for careful monitoring and adjustment of antibiotic therapy based on clinical response and susceptibility testing, as indicated by the study 3.
Overall, the management of Staphylococcus bacteremia requires a comprehensive approach that takes into account the specific characteristics of the infection, the patient's underlying health status, and the most recent evidence-based guidelines, as provided by the study 2.
