ANTIBIOTIC ASSAY MEDIUM NO. 38 (VEG.)

Antibiotic Veg Assay Medium No. 38 is prepared by incorporating vegetable peptones in place of animal peptones, making the medium, BSE-TSE risks free. This medium can be used for the same purpose of Antibiotic Medium No. 38 which follows the specification of CFR and is routinely employed for agar diffusion assay of Ticarcillin using Gram negative test organisms especially Pseudomonas aeruginosa. This medium is used as both base agar and seed agar for assay of Ticarcillin.
Freshly prepared plates should be used for antibiotic assays. Test organisms are inoculated in sterile seed agar pre-cooled to 40-45?C and spread evenly over the surface of solidified base agar.
