GNR, Gram-negative rods. *The percentage refers to the proportion of all pathogenic bacterial and fungal isolates. Anaerobes, coagulase-negative staphylococci and bacterial isolates of uncertain pathogenicity were not included. † CA: Community-acquired infection, i.e. blood-culture obtained ≤ 48 hours from of admission. ‡ Hospital-acquired infection: Blood-culture obtained > 48 hours from admission.
