Activity of tetracycline, doxycycline, and minocycline against methicillin-susceptible and -resistant staphylococci.
Tetracycline, doxycycline, and minocycline were evaluated for their antibacterial activity against methicillin-susceptible and -resistant isolates of Staphylococcus. At clinically achievable levels both doxycycline and minocycline were more active than tetracycline against methicillin-susceptible organisms. Tetracycline and doxycycline had no activity against methicillin-resistant staphylococci...
متن کاملComparative susceptibility of anaerobic bacteria to minocycline, doxycycline, and tetracycline.
The comparative susceptibility of 622 recent clinical isolates of anaerobic bacteria to minocycline, doxycycline, and tetracycline was determined by an agar-dilution technique. In addition to Bacteroides fragilis, a variety of other anaerobic bacteria was resistant to achievable blood concentrations of tetracycline (55% inhibited by 6.25 mug/ml) and doxycycline (58% inhibited by 2.5 mug/ml). In...
متن کاملAntigen specific for bacteria resistant to tetracycline.
Antisera produced against envelope fractions of tetracycline-resistant Escherichia coli and supernatant fluid of disrupted cells of tetracycline-resistant Salmonella typhi were adsorbed with the corresponding fractions of susceptible cultures. With these sera, cross-reacting antigens were demonstrated in the following fractions obtained from tetracycline-resistant strains: envelopes of E. coli,...
متن کاملEnvironmental Macrolide–Lincosamide–Streptogramin and Tetracycline Resistant Bacteria
Bacteria can become resistant to antibiotics by mutation, transformation, and/or acquisition of new genes which are normally associated with mobile elements (plasmids, transposons, and integrons). Mobile elements are the main driving force in horizontal gene transfer between strains, species, and genera and are responsible for the rapid spread of particular elements throughout a bacterial commu...
متن کاملCharacterization of unusual tetracycline-resistant gram-positive bacteria.
Tetracycline-resistant Tet M-negative isolates of Actinomyces viscosus, Eubacterium lentum, Mobiluncus curtisii, and Mobiluncus mulieris were screened with the Tet K, Tet L, and Tet O DNA probes. Ten (71%) of the resistant Mobiluncus strains hybridized with the Tet O probe, two of the three E. lentum strains hybridized with the Tet K probe, and the A. viscosus isolate hybridized with the Tet L ...
