In 70 strains of the genus Enterococcus belonging to 16 species and isolate
d from clinical material, animals and the environment, a hydroxamic class o
f siderophores was detected with the aid of chemical and biological rests.
A correlation between siderophore activity and species affiliation was foun
d: E. faecalis strains showed the highest siderophore activity. A correlati
on between siderophore activity and pathogenicity could not be confirmed.
