tn when compared to other drugs that means o guantity 't can kill or inhib?the growth of bacteriom no CLINICAL APPLICATIONeffectively wan ?hers. The broth dilution test can be used to determine the effectiveness of an antibiotic. In this test, serial dilutions of the antibiotie were set up in the wells of a microtiter plate. Equal amounts of broth eulture of Staphylococcus aureus were added to each well. After incubation, the wells were examined for bacterial growth. Wells with no growth were subcultured in nutrient broth without the antibiotic. Results were recorded as (+) for growth and (-) for no growth. Antibiotic Dilution Growth Growth in Subculture 1:10 through 1:70 1:80 1:90 1:100 1:200 through 1:500 1:10 through 1:150 1:160 1:170 1: i80 1:190 througd: 1:500 What is the minimum bactericidal concentration of each antiluiotic?A-180 B-LO What is the minimum bacteriostatic concentration A-:100,1170 Which antibiotic is more effective against Staphylococcus aureus?
