[Sensitivity of Kingella kingae to antibiotics].

Kingella kingae is a small Gram negative rod of the Neisseriaceae family, formerly called Moraxella kingae. This microorganism is found occasionally in the oral cavity and is capable of causing infections. We report three cases of septic arthritis in children due to K. kingae. In vitro susceptibility of the recovered strains was tested using determination of MICs in agar. The strains were susceptible to penicillin, ampicillin, ticarcillin, cephalothin, cefotaxime, gentamicin, chloramphenicol, tetracycline, trimethoprim-sulfamethoxazole, and pefloxacin, less susceptible to erythromycin and resistant to lincomycin (MIC 32 mg/l).
