This work aimed the study of acquisition of iron from different compounds b
y EIEC strains. Seven serotypes were studied (O28ac.H-, O29:H-, O136:H-, O1
44:H-, O152:H-, O164:H- and O167:H7(-)), in a total of 31 strains. All sero
types were able to use distinct iron sources: hemin, hematin, hemoglobin, o
votransferin, lactoferrin, transferrin and ferritin.
