You need to know that the various antibiotic drugs are not all equally effective in controlling the bacteriagrowth. Take for example the Staphylococcus aureus. Different antibiotic drugs can have different effects. The most effective antibiotic drug against that bacteria is Penicillin, because it controlled the growth of the bacteria the most.
