Method Researchers developed two novel pharmacodynamic models that assign mechanisms of action to fluoroquinolone antimicrobial agents (growth inhibition or death stimulation) and compared the abilities of these models and two other maximum effect models—our previously described net effect model (ref 5 in article) and the MIC-based model reported by Meagher and colleagues (ref 18 in article) to describe and predict the changes in bacterial population dynamics during in vitro system experiments where S. aureus was exposed to a series of simulated ciprofloxacin pharmacokinetic profiles (refs 4,5 in article).
Comments Values for bacterial growth in vitro are: for susceptible and resistant populations of both MRSA 8043 and MRSA 8043C0-1 0.99h^-1(9.16) and 0.66h^-1 (2.58), respectively. For susceptible and resistant populations of both MRSA 8282 and MRSA 8282C0-1, 0.93h^-1 (7.05) and 0.70h^-1 (2.84), respectively. In vitro. Growth rate of 0.99h^-1 corresponds to doubling time of 42min. See BNID 105553
