Required information Skip to question Kirby-Bauer Method Read the overview and complete the interactivities that follow. Antimicrobials are compounds that kill or inhibit the growth of microorganisms. Natural compounds produced by some microorganisms can be used to kill or inhibit other microorganisms. These are referred to as antibiotics. Some antimicrobials are natural compounds that are altered in the laboratory (semi-synthetics), and some antimicrobials are completely made in the laboratory (synthetics). The effectiveness of an antibiotic depends on its mode of action on the microbial cell and its ability to be transported into the cell. Some antibiotics work against a wide range of microorganisms, while others are more effective against one group such as gram-negative bacteria. Because of the rise of antibiotic-resistant bacteria, medical treatment for certain infections has changed. Strains of drug-resistant Staphylococcus aureus, Mycobacterium tuberculosis, Neissiera gonorrheae and others have developed. In infections where the standard drug of choice is not effective, it becomes important to isolate the causative agent and determine its susceptiblity to different antimicrobials. One of the tests used to determine the antibiotic sensitivity of a pathogen is the Kirby-Bauer method. Penicillin is made by a fungus and used to kill bacterial cells. Therefore, penicillin is an example of a(n) multiple choice 1 semi-synthetic synthetic antibiotic An
