Staphylococcus aureus expresses a cell surface protein that binds both IgG and beta(sub 2)-glycoprotein I

Article Abstract:

A study was conducted to show that Staphylococcus aureaus expresses a cell surface protein called Sbi that binds immunoglobulin G and beta2-glycoprotein I. The Phast system was utilized to evaluate proteins determined from bovine, human and rate serum. Escherichia coli strain MC1061 was then utilized for the production of fusion protein. Experimental results indicated that protein Sbi is expressed on the staphylococcal cell surface at different levels between strains.

The staphylococcus aureus scdA gene: a novel locus that affects cell division and morphogenesis

Article Abstract:

The staphylococcus aureus scdA gene's role in cell division and morphogenesis was investigated by analyzing a new scdA mutant strain, KB323. The mutant scdA strain was obtained through the insertion of the gene's internal fragment into the NCTC 8325-4. Results have shown that the scdA is essential to the peptidoglycan metabolism and cell development even though its transcription is unaffected by LytS and LytR.

The effects of adherence to silicone surfaces on antibiotic susceptibility in Staphylococcus aureus

Article Abstract:

The growth and antibiotic susceptibility of planktonically growing Staphylococcus aureus and those attached to silicone discs cut from Foley catheters were analyzed. Young adherent cultures that comprise single well-spaced cells exhibited significant decreases in antibiotic susceptibility. Results indicate that biofilm formation is not important for decreases in antibiotic susceptibility in adherent bacteria.
