The in vitro susceptibility to linezolid shown by nine Greek
isolates of Coxiella burnetii derived from patients with
acute Q fever was investigated. MICs of linezolid were compared with those of pefloxacin, ciprofloxacin, ofloxacin, trovafloxacin, doxycycline, and clarithromycin using the shell vial assay. MICs of
linezolid and clarithromycin ranged from 2 to 4 µg/ml; those of
doxycycline, trovafloxacin, and ofloxacin ranged from 1 to 2 µg/ml;
those of pefloxacin ranged from 1 to 4 µg/ml; and those of
ciprofloxacin ranged from 4 to 8 µg/ml. Linezolid was effective in
controlling intracellular parasites in cultures of Vero cells infected
by C. burnetii. No bactericidal activity
by linezolid was obtained against C.
burnetii at 8 µg/ml.
