General description

Staphylococcus aureus Wood 46 is protein A deficient and spa negative. It shares 98% to 99% genome identity with S.aureus and shows a lower surface expression of cell wall-associated protein A.


(Not intended for use as a starter culture.)
Staphylococcus aureus has been used:
  • to mimic infection and induce fever in Pekin duck
  • to test its effect on hemocyte morphology in hemolymph samples from beetle Tenebrio molitor larva
  • in the antibacterial activity and minimum inhibitory concentration (MIC) assay with gedunin and 7-deacetoxy-7αhydroxygedunin potassium salt

Wood 46, a non-protein A producing S. aureus strain, prepared by the same method as P7155 (Protein A, crude cell suspension-Cowan strain), may be used as a control in protein A-immunoglobulin binding studies.

Biochem/physiol Actions

Staphylococcus aureus Wood 46 displays reduced virulence compared to the S. aureus. This isolate is useful in understanding protein A role in pathogenesis and virulence.

Physical form

Formalin-fixed crude cell suspension of essentially non-viable S. aureus (Wood 46 strain) in 0.05 M potassium phosphate buffer, pH 7.5, containing 0.2% sodium azide

Preparation Note

Produced in pure culture.

Analysis Note

This strain binds less than 10% of the rabbit IgG bound by P 7155 as assayed by a modification of the method of Kessler.
