摘要
测定216株葡萄球菌(126株金葡菌,90株凝固酶阴性葡萄球菌)对8种临床常用抗生素药敏。结果为:医院内携带的金葡菌对青霉素G、红霉素、林可霉素耐药率分别为76.42%、61.36%、27.26%,对头孢噻啶、利福霉素敏感性较好。医院内表葡菌对青霉素G、红霉素、林可霉素耐药率分别达65.29%、58.82%、50%。故治疗医院内金葡菌、表葡菌感染时要选用有效药物。医院内携带的金葡菌产酶率81.40%,CNS产酶率71.11%,绝大多数产酶株对青霉素G耐药,头孢噻啶对产酶株有良好的抗菌活性。
A total of 216 staphylococcus strains were tested for susceptibility to 8 antibiotics with dollbling dilution of test tubes. Experiment showed: 76.42%, 61.36% and 27.26% of nosocomial S. aureus strains were resitant to penicillin G. engthromycin and lincomycin respectively 1.89% and 2.83% of S. aureus strains resisted to cefaloridine and rifamycin. These patterns were also seen with S. epidermidis.80.08% of S. aureus strains were beta-lactamase producers. 71.11% of CNS produced beta-lactamase. Most of staphylococcal strains which produced beta-lactamase were resistant to penicillin G. The factors influencing sensitivity beta-lactam antibiotics are discussed.
