Modulation of the intestinal flora of mice by parenteral treatment with broad-spectrum cephalosporins.

abstract：:Pharmacological modeling of antiparasitic treatment based on a drug's pharmacokinetic and pharmacodynamic properties plays an increasingly important role in identifying optimal drug dosing regimens and predicting their potential impact on control and elimination programs. Conventional modeling of treatment relies on m...
