Presence of Tetracycline Resistance Determinants and Susceptibility to Tigecycline and Minocycline

Abstract
No relation between the presence of tetracycline resistance determinants tet(A) to tet(E) and the MICs of tigecycline was observed for Enterobacteriaceae, although tetracycline-susceptible isolates were more susceptible overall to tigecycline, whereas the presence of tet(M) in Staphylococcus aureus was associated with higher MICs of minocycline.
