The presence of beta -lactam antibiotics in test material such as food, infusions, vaccines, blood for transfusion, body fluids, etc. may be determined by: seeding a nutrient medium with a beta -lactamase generating bacterium or spores thereof; applying a sample of said test material to a site on the so-called nutrient medium; then incubating the medium under conditions inducive to the generation of beta -lactamase by said bacteria; and assaying the beta -lactamase thus produced. |
