A rapid bioassay for gentamicin levels in serum was developed by using a strain of Klebsiella pneumoniae that has multiple resistance to antibiotics. Assays were comparable when performed on either small or large petri plates, and results were available in 2 to 4 h. Studies showed an overall recovery of 97.6% for gentamicin alone or 104.5% in the presence of commonly used antibiotics. The procedure can be performed without the need to inactivate other antibiotics that may be present in the serum sample.
通过使用对多种抗生素具有多重耐药性的肺炎克雷伯菌菌株,开发了一种用于检测血清中庆大霉素水平的快速生物测定法。在小培养皿或大培养皿上进行测定时结果相当,2至4小时内即可获得结果。研究表明,单独检测庆大霉素时总体回收率为97.6%,在存在常用抗生素的情况下回收率为104.5%。该检测程序无需灭活血清样本中可能存在的其他抗生素即可进行。
