In 180 staphylococcal strains of diverse origin belonging to 26 specie
s a hydroxamate class siderophore was detected with chemical test. In
65% of investigated strains it was identified by biological assay as a
erobactin. A correlation between hydroxamate siderophore production, s
pecies affiliation and pathogenicity was not found. In 14 (7.8%) strai
ns a catechol class siderophore, beside aerobactin, was detected.
