title: [Utilization of exogenous siderophores by enterococci].
abstract: The study was undertaken to investigate the ability of enterococci to assimilate iron via siderophores of bacteria living in the same habitats in the human organism. The potential recipients of exogenous siderophores were six Enterococcus faecalis and six Enterococcus faecium strains, isolated from clinical materials of human origin. The donors of siderophores were Gram-negative rods (various species of the Enterobacteriaceae, Pseudomonas and Acinetobacter) and Gram-positive cocci (various species of Staphylococcus and Streptococcus). All of the investigated E. faecium and only two E. faecalis strains demonstrated the ability to utilize the siderophores of the aforementioned bacterial groups, predominantly the chelators of Gram-negative rods, those of Gram-positive cocci were utilized to a smaller extent. Four recipient strains from E. faecalis species did not demonstrate the ability to utilize siderophores synthesized by all of 40 investigated donor strains.
