Antibacterial properties of alafosfalin combined with cephalexin

Abstract
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 μg/ml. The assay is simple to carry out, and duplicate assays can be performed on as little as 40 μl of serum.
