Certain microorganisms have an inhibitory effect on the growth and reproduction of other microorganisms, and this phenomenon is called antibiotics, and these microorganisms and their preparations are called antibiotics. The antibiotic has good killing and inhibiting effects on various infections caused by gram-positive bacteria, gram-negative bacteria and the like, and is widely applied to the aspects of clinic, veterinary medicine, agriculture and the like. While antibiotics are widely used, the harm of the residues of the antibiotics in animal food to human bodies is attracting more and more attention.

Wherein, the microbiological assay method of the antibiotic potency, the tube-disc method and the drug sensitive paper sheet method are the general methods of the antibiotic potency at home and abroad at present. The tube-disc method is to utilize the diffusion of antibiotics in the agar culture medium for culturing specific experiments to form a circular area containing antibiotics for inhibiting the propagation of experimental bacteria or killing the experimental bacteria. The action mechanism of different antibiotics for different experimental bacteria is different, and no matter sterilization or bacteria growth inhibition, a very obvious inhibition zone can be observed through an agar culture medium. The larger the zone of inhibition, the stronger the bacteriostatic action of the drug, and the antibiotic titer can be determined by measuring the size of the zone of inhibition of the microorganism.
