Conspicuous ingestion of Staphylococcus aureus organisms by murine fibroblasts in vitro.
A conspicuous adhesion of Staphylococcus aureus organisms to murine cutaneous fibroblasts and NIH/3T3 cells cultured in vitro and subsequent ingestion of S. aureus organisms by these fibroblasts are described. In the present experimental system, only fibroblasts-adhering S. aureus organisms were efficiently ingested by fibroblasts unlike S. epidermidis and S. saprophyticus. These findings might suggest a correlation between the pathogenesis of S. aureus and its intracellular localization in non-professional phagocytes such as fibroblasts in a special reference to its higher pathogenicity than those of coagulase negative counterparts.
