Antimicrobial Susceptibility and Clinical Sources of Dolosigranulum pigrum Cultures

Antimicrobial susceptibilities of 27 clinical isolates of Dolosigranulum pigrum were determined. All were susceptible to amoxicillin, cefotaxime, cefuroxime, clindamycin, levofloxacin, meropenem, penicillin, quinupristin-dalfopristin, rifampin, tetracycline, and vancomycin. Fifteen of the isolates were intermediate to chloramphenicol. One isolate was resistant to trimethoprim-sulfamethoxazole. Two isolates were susceptible, 10 were intermediate, and 15 were resistant to erythromycin.
