aAll cases have cleared their blood cultures. Cases 1 and 7 used ERV after blood culture clearance, whereas cases 3 and 9 used ERV before blood culture clearance.
bTime to ERV administration from positive culture was not possible to calculate because patient was a transfer with no documentation of timing of first culture in cases 2 and 3, while in case 8 no culture was isolated from the patient (empiric therapy).
c Enterococcus faecium growing from blood and Bacteroides fragilis from fluid.
dThe subject’s symptoms resolved initially, but the subject had a 30-day recurrence, followed by 30-day mortality.
ePatient was administered eravacycline for the purpose of double coverage at another institution before referral to the current institution. In the current study institution, no double coverage or combination agent was administered.
fNo organisms were isolated because the regimen was empiric.
gTime to ERV administration from positive culture was not possible to calculate because therapy was empiric with no culture.
