Synthesis and structure-activity relationships of novel 9-oxime acylides with improved bactericidal activity.
TL;DR: This study suggests that the 9-oxime acylides possess a bactericidal mechanism that is different from the traditional near-complete inhibition of protein synthesis, which provides a foundation for the rational design of macrolide antibiotics.

[Tetracyclines: bacteriostatic or bactericidal drugs? In vitro studies with rolitetracycline, minocycline and doxycycline (author's transl)].
TL;DR: Minimal bacteriostatic and minimal bactericidal concentrations of rolitetracycline, minocycline and doxycycline on 20 different E. coli serotypes and 16 staphylococcus aureus strains have been compared in bouillon and serum to find out whether these concentrations can be improved by addition of serum.
