Allgemeine Beschreibung

Staphylococcus aureus Wood 46 is protein A deficient and spa negative.[1] It shares 98% to 99% genome identity with S.aureus[1] and shows a lower surface expression of cell wall-associated protein A.[2]

Anwendung

(Not intended for use as a starter culture.)
Staphylococcus aureus has been used:
  • to mimic infection and induce fever in Pekin duck[3]
  • to test its effect on hemocyte morphology in hemolymph samples from beetle Tenebrio molitor larva[4]
  • in the antibacterial activity and minimum inhibitory concentration (MIC) assay with gedunin and 7-deacetoxy-7αhydroxygedunin potassium salt [5]

Wood 46, a non-protein A producing S. aureus strain[6], 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. Wirkung

Staphylococcus aureus Wood 46 displays reduced virulence compared to the S. aureus.[1] This isolate is useful in understanding protein A role in pathogenesis and virulence.[2]

Physikalische 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

Angaben zur Herstellung

Produced in pure culture.

Hinweis zur Analyse

This strain binds less than 10% of the rabbit IgG bound by P 7155 as assayed by a modification of the method of Kessler[7].

Poultry, like mammals and other birds, develop fever when exposed to compounds from gram-negative bacteria. Mammals also develop fever when exposed to the constituents of viruses or gram-positive bacteria, and the fevers stimulated by these different pathogenic classes have discrete

Protein A in Staphylococcus aureus is encoded by the spa (staphylococcal protein A) gene and binds to immunoglobulin (Ig). The S. aureus strain Wood 46 has been variously reported as protein A-deficient and/or spa negative and used as a control

Tachykinins (TKs) are a group of conserved neuropeptides. In insects, tachykinin-related peptides (TRPs) are important modulators of several functions such as nociception and lipid metabolism. Recently, it has become clear that TRPs also play a role in regulating the insect

Protein A of Staphylococcus aureus can be detected on cell walls of intact bacteria by use of radioactively labeled myeloma globulin. Of 156 strains of S. aureus, 141 (90%) contained protein A. None of 47 S. epidermidis strains was positive

Questions

  1. Hello, I'm wondering if this "Staphylococcus aureus, wood 46 strain" is deactivated or not. Additionally, do you have the corresponding aptamer or antibody of this strain?

    1 answer
    1. This product is a formalin-fixed crude cell suspension of essentially non-viable S. aureus in 0.05 M potassium phosphate buffer containing 0.2% sodium azide. Currently, there is no corresponding aptamer or antibody for the Wood 46 Strain.
