임상가검물에서 분리된 Enterobacter 및 Citrobacter의 각종 항균제에 대한 감수성

Abstract

Twenty nine strains of Enterobacter and 18 strains of Citrobacter isolated from various clinical specimens were tested for antimicrobial susceptibility to 20 drugs including quinolones. The most frequent isolation source of Enterobacter and Citrobacter was urine. Among the isolated Enterobacter’ all strains were susceptible to enoxacin(Ex), norfloxacin(Nf), ciprofloxacin (Cp), ofloxacin (Of) and pefloxacin(Pf). 3.4-17.2% of the strains were resistant to rifampin(Rf), moxalactam(Mx), and nalidixic acid(Na). 34.5-65.5% of the strains were resistant to chloramphenicol (Cm), trimethoprim (Tp), amikacin( Ak), cefamandole(Cf), streptomycin (Sm), tetracycline(Tc), gentamicin(Gm), kanamycin(Km) and sulfisomidine(Su) and 93.1-96.6% of the strains were resistant to ampicillin(Ap), cephalothin(Ct), and tobramycin (To). In Citrobacter, all strains were susceptible to Ex, Nf, Cp, Of, Pf, and Mx, 11.1-33.3% of the strains were resistant to Na, Rf, Gm, Ak, Cf, To, and Tp, 44.4-55.6% of the strains to Sm, Km, Cm, Tc, and Su, and all strains were resistant to Ap and Ct.
