The effect of antibacterial drugs on the weight of mice

Abstract

The oral administration to mice of certain antibacterial drugs brings about profound and lasting changes in their fecal flora; the duration of these changes is conditioned by the composition of the diet fed the animals (1). It will be shown in the present paper that the growth rates of mice and some at least of their nutritional requirements are also affected by the administration of antibacterial drugs. © 1963, Rockefeller University Press., All rights reserved.
