Table 15. Antimicrobial treatment of human ehrlichiosis (n = 356) considered effective*.

Antimicrobial treatment	Number of cases n (%)
Doxycycline	298 (83.7)
Tetracycline	21 (5.9)
Chloramphenicol	20 (5.6)
Minocycline	4 (1.1)
Rifampicin	2 (<1)
Multiple compounds	11 (3.1)
Doxycycline + chloramphenicol	8
Doxycycline + rifampicin	2
Tetracycline + chloramphenicol	1

* tetracyclines (doxycycline, minocycline) and rifampicin were considered effective/appropriate; chloramphenicol was also considered effective/appropriate, although evidence is limited; beta-lactams, quinolons, macrolides, aminoglycosides, glycopeptides, nitroimidazoles, sulphonamides, and lincosamide were considered ineffective/inappropriate.
