一般說明
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.
應用
(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.
生化／生理作用
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.
外觀
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
準備報告
Produced in pure culture.
分析報告
This strain binds less than 10% of the rabbit IgG bound by P 7155 as assayed by a modification of the method of Kessler.

Procedures are detailed for the rapid isolation of representative cell membrane antigens with protein A-bearing staphylococci as an adsorbent for IgG antibodies complexed with the antigens. Cell surface membrane proteins were radioiodinated and solubilized in nonionic detergent. Specific antisera were

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

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

To induce the water solubility of hexagonal boron nitride (h-BN), we exfoliated and functionalized bulk h-BN with hydroxyl groups (h-BN-OH-n). Short-term studies showed that h-BN-OH-n induced low cytotoxicity in different models: insect haemocytes (in vivo), human erythrocytes and mouse fibroblasts

The evolutionary success of insects is undoubtedly related to a well-functioning immune system. This is especially apparent during insect development by the adaptation of individuals to the changing risk of infection. In addition, current studies show that the insect immune
