ANTIBIOTIC ASSAY MEDIUM NO. 39 (VEG.)

Antibiotic Veg Assay Medium No. 39 is formulated by incorporating vegetable peptones in place of animal peptones, making the medium BSE-TSE risks free. Grove and Randall have elucidated those antibiotic assays and media in their comprehensive treatise on antibiotic assays. Schmidt and Moyer have reported the use of antibiotic assay medium for the liquid formulation used in the performance of antibiotic assay. This medium is prepared in accordance with the USP and the FDA. This medium can be used for the same purpose of Antibiotic Medium No. 39 employed widely for turbidometric assay of Neomycin using Klebsiella pneumonia and Tylosin using Staphylococcus aureus as the test organisms. Turbidimetric methods for determining the potency of antibiotics are inherently more accurate and more precise than comparable agar diffusion procedures.
