Thirteen clinical isolates of Escherichia coli resistant to ceftazidime that possessed an AmpC and other (b-lactamases were identified. The effectiveness of different formulations of piperacillin/tazobactam to other b-lactams was compared. Antibiotic susceptibility testing, polymerase chain reaction, amplification of blaTEM, blaSHV and blaAmpC, and enzyme-linked immunosorbent assays to identify AmpC b-lactamases were performed. Hydrolysis rates were obtained and residual enzymatic activity was determined. Cefepime and ertapenem were more active than piperacillin/tazobactam. In contrast, increasing the relative proportion of tazobactam improved susceptibility testing. Twenty micromolar tazobactam inhibited total b-lactamase activity (as measured by nitrocefin hydrolysis rates) by greater than 75% against all isolates tested: in 11 of 13 E. coli isolates, total b-lactamase activity was inhibited by 90%. The observed differences between MIC determinations and susceptibility to enzymatic inactivation by tazobactam against E. coli containing AmpC and other b-lactamases may be due to the final tazobactam concentration achieved in the periplasmic space. Factors determining this are critical considerations in assessing b-lactamase inhibitor potency. |

十三株臨床分離出來的大腸桿菌已經被鑒定出來,它們對可以擁有AmpC(這不太確定)和b-內酰胺酶的頭孢他啶具有抗藥性。對哌拉西林/三唑巴坦和其他b-內酰胺的 不同配方的有效性進行比較。采用藥敏試驗、PCR、blaTEM, blaSHV以及blaAmpC的擴增(好像單詞拼錯了,不知道什么意思)以及ELISA方法對AmpC b-內酰胺酶進行檢測。得到水解率和剩余酶的活性。頭孢吡肟和厄他培南的活性強于哌拉西林/三唑巴坦。相反,增加三唑巴坦的相對比例可以改善藥敏試驗。20mol三唑巴坦對所有分離出來的菌株,其抑制總b-內酰胺酶活性(根據(jù)nitrocefin的水解率計算)大于75%:在13株大腸桿菌中有11株,總b-內酰胺酶活性被抑制率為90%。三唑巴坦對含有AmpC和其他b-內酰胺酶的大腸桿菌的MIC(最低抑菌濃度?)和酶失活的易感性,二者之間的區(qū)別取決于細胞周質間隙的三唑巴坦的最終濃度。決定這些的因素是評估β-內酰胺酶抑制劑效力時至關重要的考慮因素。 |
