Abstract
Growth rates, siderophore secretion, and bacterial proteins of two cli nical isolates of Staphylococcus aureus were studied over 72 h of grow th in iron-supplemented and iron-restricted chemically defined media. Under iron restriction the growth rates were decreased to different ex tents 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 sid erophore efficiency.
