Microbial kinetics have been employed to study the mechanism of antibacterial activity of chloroquine on S. aureus. Cultures treated with the drug in growth medium showed biphasic steady-state generation curves, the apparent rate constant for the phase I was smaller than for phase II. The bacteriostatic activity of the drug was associated with the first phase of drug-bacteria reaction, which was also affected by changes in pH of the growth medium.
