RESUMO

Atypical tetracyclines were active against Escherichia coli and Staphylococcus aureus strains containing determinants that mediate resistance to typical tetracyclines by efflux (Tet B and Tet K) or ribosomal protection (Tet M) mechanisms. The results support recently published data that tetracyclines are divisible into at least two classes on the basis of their modes of action.
