Chloramphenicol Bioassay [PDF]

Antimicrobial Agents and Chemotherapy, 1979
An accurate plate diffusion bioassay for chloramphenicol is described, in which the fast-replicating Beneckea natriegens and 1.5% salt agar are used. Zones of inhibition were well defined after 3 h, and the limit of sensitivity of the method was around 2 μg/ml. The concurrent presence of gentamicin did not influence
