CRP and Sepsis: For children under 3 months of age without sepsis and a local community MRSA prevalence of < 10%, cefotaxime, ceftriaxone, or ceftazidime in combination with an anti-staphylococcal penicillin (such as oxacillin) is suggested.[28] In Case 1, due to the prolonged duration of illness (>1 week), presence of sepsis, and in conjunction with WBC, CRP, and ultrasound findings, the antibiotic regimen was adjusted to vancomycin within 8 hours of admission.
