An accurate, plate diffusion bioassay for ticarcillin, utilizing the fast-replicating Beneckea natriegens and 4% salt agar, is described in this report. Zones of inhibition were well defined after 3 h, and the limit of sensitivity was around 5.0 mug/ml. The assay is simple to carry out, and duplicate assays can be performed on as little as 40 mul of serum.
本报告介绍了一种利用快速繁殖的纳氏贝内克氏菌和4%盐琼脂对替卡西林进行准确的平板扩散生物测定法。3小时后抑菌圈清晰可见,灵敏度极限约为5.0微克/毫升。该测定法操作简单,仅用40微升血清即可进行重复测定。
