Growth rates, siderophore secretion, and bacterial proteins of two clinical isolates of Staphylococcus aureus were studied over 72 h of growth in iron‐supplemented and iron‐restricted chemically defined media. Under iron restriction the growth rates were decreased to different extents depending on the strain. Production of siderophore was detected in the mid‐exponential and stationary phases of growth. The expression of iron‐regulated proteins of 81, 23, and 17 kDa was time‐dependent, associated with the same stage of growth, and might be involved in siderophore efficiency.
