一般描述

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.

应用

(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.

外形

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

制备说明

Produced in pure culture.

分析说明

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

Complete Genome Sequence of Staphylococcus aureus Strain Wood 46.

Manasi Balachandran et al.

Genome announcements, 5(13) (2017-04-01)

Here, we report the first complete genome sequence of the Staphylococcus aureus strain Wood 46. Wood 46 has played an important role in understanding the virulence and pathogenesis of S. aureus infections. This report will assist efforts in vaccine development against

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
