摘要
Individual strains of Staphylococcus aureus have different capacities to become internalized by osteoblasts. Here we report that the levels of sigma(B) expressed by S. aureus correlate with the capacity of this bacterium to be internalized by osteoblasts. However, sigma(B) is not essential for internalization and does not necessarily account for the differences in the capacities of strains to be internalized.
