Actinomyces spp have been increasingly associated with endodontic infections. However,
the antimicrobial susceptibility of this genus has not been studied extensively. The objective
of this study was to determine the susceptibility of oral isolates of Actinomyces naeslundii,
Actinomyces gerencseriae, Actinomyces israelii, Actinomyces viscosus, and Actinomyces
odontolyticus to amoxicillin, clindamycin, doxycycline, metronidazole, and moxifloxacin
using in vitro assays. The minimum inhibitory concentration (MIC) of each bacterial isolate …
