Table 1. Evolution of the Susceptibilities of the Enterococcus Isolates From Blood and CSF.
Drug | Isolate 1 Blood Day 0 MIC | Isolate 2 Blood Day 7 MIC | Isolate 3 Blood Day 15 MIC | Isolate 4 CSF Day 25 MIC |
---|---|---|---|---|
Vancomycin | >256 (R) | >256 (R) | >256 (R) | >256 (R) |
Chloramphenicol* | S | I | I | R |
Doxycycline* | S | S | S | R |
Linezolid* | S | S | S | R |
Synercid* | S | S | S | R |
Rifampin* | R | R | R | R |
Daptomycin | 1 (S) | NT | NT | 2 (S) |
Tigecycline | NT | 0.25 (NI) | 0.05 (NI) | 0.125 (NI) |
Susceptibility testing for these antimicrobials were performed using disk diffusion method and therefore MICs are not available.
MIC indicates minimum inhibitory concentration; S, susceptible; I, intermediate; R, resistant; NT, not tested; CSF, cerebral spinal fluid; NI, no interpretation available.
