Abstract

The ability of Staphylococcus aureus,Klebsiella.pneumoniae isolated from rhinitis cases to produce siderophores as avirulence factor was estimated. Rogers method used for extraction of siderophores and then the chemical and biological assay performed to detect siderophore.The results showed ability of all strains to produce siderophores which confirmed its roles in pathogenesis.
