Defective killing of enterococci: a common property of antimicrobial agents acting on the cell wall.

abstract：:Recent pharmacokinetic studies that included children found that serum drug levels were low compared to those of adults for whom the same dosages were used. This study aimed to characterize the pharmacokinetics of pyrazinamide and ethambutol in Malawian children and to examine the impact of age, nutritional status, an...
