Foi investigada a aquisição de ferro por cepas de EIEC a partir de diferentes compostos. Sete sorotipos foram estudados (O28ac.H-, O29:H-, O136:H-, O144:H-, O152:H-, O164:H- and O167:H7), totalizando 31 cepas. Foi observado que todos os sorotipos puderam usar fontes de ferro distintas: hemina, hematina, hemoglobina, ovotransferrina, transferrina, lactoferrina e ferritina.
This work aimed the study of acquisition of iron from different compounds by EIEC strains. Seven serotypes were studied (O28ac.H-, O29:H-, O136:H-, O144:H-, O152:H-, O164:H- and O167:H7-), in a total of 31 strains. All serotypes were able to use distinct iron sources: hemin, hematin, hemoglobin, ovotransferin, lactoferrin, transferrin and ferritin.
