Abstract
A total of 53 Staphylococcus aureus strains isolated from caprine mastitis were tested for surface hydrophobicity, surface Protein A (SpA), and binding capacity of fibronectin, fibrinogen and type II collagen. Strong positive correlation was found between surface hydrophobicity and SpA, and between surface hydrophobicity and 125I-fibronectin-binding. Regardless of hydrophobicity, the binding of fibrinogen was moderate and type II collagen binding was low. The results indicate that SpA and fibronectinbinding protein contribute to the high relative surface hydrophobicity of S. aureus associated with caprine mastitis.
Keywords: bacterial surface hydrophobicity, protein A (SpA), fibronectin, fibrinogen, type II collagen
Sammendrag
Totalt 53 stammar av Staphylococcus aureus frå mastitt hjå geit vart testa for overflate-hydrofobisitet, for innhaldet av overflate-protein A (SpA) og for evnen til å binde fibronektin, fibrinogen og type II kollagen. Det vart påvist sterk positiv korrelasjon mellom over flate-hydrofobisitetog SpA og mellom overflate-hydrofobisitet og binding av 115I-flbronek-tin hos bakteriane. Uavhengig av hydro fobi si teten var bindinga av fibrinogen moderat og bindinga av type II kollagen svak. Resultata indikerer at SpA og fibronektinbindande protein bidreg til den relativt høge overflate-hydrofobisiteten hjå S. aureus frå mastitt hjå geit.
