Staphylococcus aureus isolated from mastitis (14 bovine and 11 ovine s
trains) exhibited an ability to adhere to epithelial primary cultures
from ovine mammary gland and to a rat epithelial cell line, RIE-1. Str
ain differences in the degree of adherence were observed in both cases
. These differences were maintained when comparing different epithelia
l sources (rat vs. ovine). RIE-1 cells can thus be used as a model for
studying staphylococcal adherence to epithelial cells. Changes in bac
terial adherence were observed according to the bacterial growth phase
. The magnitude of these changes differed among strains. Bacterial cel
l surface hydrophobicity was not related to the degree of adherence to
mammalian epithelial cells.
