Transduction of tetracycline resistance in Staphylococcus epidermidis.
Fourteen Staphylococcus epidermidis strains were biotyped according to the scheme of Baird-Parker and tested for their sensitivities to S. epidermidis typing phages. Tetracycline-susceptible strains were tested for the capacity to be transduced to resistance. Five strains, all of biotype 1, were lysed by one or more phages. Five of eight biotype 1 strains were transduced to tetracycline resista...
متن کاملCo-transduction of plasmids mediating resistance to tetracycline and chloramphenicol in Staphylococcus aureus.
Independent plasmids mediating resistance either to tetracycline (Tc) or chloramphenicol (Cm) were transduced successively into Staphylococcus aureus strain 8325. From this doubly resistant donor strain, Tc was co-transduced with a frequency of 40 to 50% when Cm was selected. Co-transduction of Cm was 5 to 10% with Tc selection. Plasmid elimination was infrequent and restricted to the Cm plasmi...
متن کاملDetection of tetracycline resistance genes, aminoglycoside modifying enzymes, and coagulase gene typing of clinical isolates of Staphylococcus aureus in the Southwest of Iran
Objective(s): The aim of the present study was to determine the aminoglycoside modifying enzymes (AMEs) encoded genes, tetracycline resistance genes, and the coa based typing of Staphylococcus aureus isolates in the Southwest of Iran. Materials and Methods: Antimicrobial susceptibility of isolates was carried out by agar disk diffusion methods. Two sets of multiplex PCR mixture were used for de...
متن کاملDevelopment of resistance to novobiocin, tetracycline, and a novobiocin-tetracycline combination in Staphylococcus aureus populations.
The antibiotic sensitivity of the individual organisms of a bacterial population was determined to study the comparative rates of development of resistance of Staphylococcus aureus to novobiocin, tetracycline, and to a combination of these antibiotics. Serial subculture of S. aureus with the combination of novobiocin-tetracycline (N-T 2.5:1; the ratio in serum of patients dosed with Panalba) sh...
متن کاملThe genetics of tetracycline resistance in Staphylococcus aureus.
Eighty-one strains ofStaphylococcus aureus that appeared to be tetracycline resistant on the basis of a preliminary disc-diffusion test were examined fro resistance to tetracycline and to the semi-synthetic tetracycline, minocycline. Minimum inhibitory concentration (m.i.c.) values for both drugs were determined after induction of the strains by growth for 2 h in sub-inhibitory concentrations f...
