Abstract

Abstract
With the increase in antibiotic resistance, Methicillin-resistant Staphylococcus aureus (MRSA) has
become a global health challenge. We present a case of a 74-years-old female who was unwell with
complaints of dizziness, shortness of breath on exertion and palpitations. She had presented with
paroxysmal atrial fibrillation and Methicillin-Resistant Staphylococcus aureus (MRSA) bacteraemia
with concerns for possible endocarditis. Transesophageal Echocardiogram (TEE) performed ruled
out any evidence of endocarditis. MRSA sepsis was established based on blood cultures with unclear
sources. After 7 days on Vancomycin and Ceftaroline, her repeated blood cultures were still positive
for MRSA, so she was started on IV Cefazolin 2g and IV Daptomycin 6mg/kg every 24 hours. Her
blood culture cleared after 5 days of this therapy. Treatment strategies for patients of MRSAB need to
be individualized to achieve infection clearance, while guidelines do serve to provide a basic
blueprint of treatment plans for physicians.
