Mt. Andres et al., ANTIMICROBIAL SUSCEPTIBILITIES OF PORPHYROMONAS-GINGIVALIS, PREVOTELLA-INTERMEDIA, AND PREVOTELLA-NIGRESCENS SPP. ISOLATED IN SPAIN, Antimicrobial agents and chemotherapy, 42(11), 1998, pp. 3022-3023
The susceptibilities of 143 Porphyromonas gingivalis, Prevotella inter
media, and Prevotella nigrescens isolates to 18 antimicrobial agents w
ere tested. All P. gingivalis isolates were susceptible. In contrast,
some Prevotella spp. (17%) were resistant to beta-lactams, erythromyci
n, clindamycin, or tetracycline and carried resistance genes, ermF or
tetQ, or beta-lactamases.
