Staphylococcus aureus cells were inoculated on the cut wounds in the skin of cyclophosphamide-treated mice. Biopsy specimens were taken from three mice at 1, 3, 6, 12, 24, 36, 48 and 60 h after the inoculation and were examined by light and electron microscopies. One hour after the inoculation Staphylococcus aureus cells were seen around the cut wound and deeper into the subcutaneous tissue. By 6 h after the inoculation, Staphylococcus aureus cells formed clusters of bacterial colonies. By 36 h after the inoculation inflammatory cells, mainly polymorphonuclear leukocytes and macrophages, were seen around the clusters. Electron microscopic examination revealed fibril-like structures around the Staphylococcus aureus cells at 1 h. The Staphylococcus aureus cells were enclosed in membrane-like structures at 3 h. The membrane-like structures and the fibril-like structures were positive for Ruthenium red. By 12 h after the inoculation, the membrane-like structures increased in thickness and in electron density. Inflammatory cells were seen around but outside of the membrane-like structures at 24, 36 and 48 h. At 60 h the tissues around the membrane-like structures were degenerated and almost necrotic. These results suggest that Staphylococcus aureus cells may form biofilm in dermal or subcutaneous tissues in a neutropenic condition.
