Plasmid-protein relaxation complexes in Staphylococcus aureus.
Protein-deoxyribonucleic acid relaxation complexes have been demonstrated for six Staphylococcus aureus plasmids out of sixteen examined. Four of these encode stretomycin resistence, have molecular weights of about 2.7 x 10(6), and are isolated as supercoiled molecules that are virtally 100% relaxable by treatment with sodium dodecyl sulfate. It is probable that these four isolates represent a ...
متن کاملCadmium resistance from Staphylococcus aureus plasmid pI258
Cadmium resistance specified by the cadA determinant of Staphylococcus aureus plasmid p1258 results from the functioning of a cadmium-efflux system. In the nucleotide sequence of the DNA fragment containing the cadA determinant, two open reading frames were identified. The larger one, corresponding to a predicted polypeptide of 727 amino acid residues, is necessary and sufficient for expression...
متن کاملSpecific Coagulases of Staphylococcus Aureus
Three staphylococcal coagulases termed I, II, and III were differentiated by measuring the antibody titer of human sera. Coagulases I and II are antigenically distinct; coagulase III appears to be related to both coagulases I and II. These results were confirmed by specific neutralization experiments. These observations emphasize the importance of employing the correct type of coagulase in stud...
متن کاملGenetic control of chromosomal and plasmid recombination in Staphylococcus aureus.
Recombination-deficient mutants of Staphylococcus aureus have been isolated and found to have properties similar to those of recombination-deficient Escherichia coli. In addition, one Rec(-) mutant was found to be defective in the restriction and modification of DNA. There is a marked reduction ( approximately 10(4)-fold) in recombination between penicillinase plasmids in the Rec(-) mutants sug...
متن کاملPlasmid-Encoded Transferable mecB-Mediated Methicillin Resistance in Staphylococcus aureus
During cefoxitin-based nasal screening, phenotypically categorized methicillin-resistant Staphylococcus aureus (MRSA) was isolated and tested negative for the presence of the mecA and mecC genes as well as for the SCCmec-orfX junction region. The isolate was found to carry a mecB gene previously described for Macrococcus caseolyticus but not for staphylococcal species. The gene is flanked by β-...
