Adsorption of fibronectin onto polymethylmethacrylate and promotion of Staphylococcus aureus adherence.

abstract：:The production of delta-toxin is supposed to be responsible for various pathophysiological effects during infection with Staphylococcus aureus. We compared the effects of delta-toxin with the structurally related bee venom toxin melittin on granulocyte functions and inflammatory mediator release. Delta-toxin and melit...
