The pathophysiological role of intracellular bacteria in osteomyelitis is still a matter of debate. Here, we demonstrate for the first time the presence of Staphylococcus aureus internalized into osteoblasts in human tissue samples of a case with a chronic osteomyelitis using ultrastructural transmission electron microscope analysis.
Keywords: intracellular S. aureus; osteoblast; osteomyelitis; ultrastructural analysis.
