WebAug 12, 2010 · Bacterial pathogens are capable of exploiting these diverse iron sources through the elaboration of a variety of iron acquisition systems. (C) Bacterial pathogens can acquire iron through receptor-mediated recognition of transferrin, lactoferrin, hemopexin, hemoglobin, or hemoglobin–haptoglobin complexes. WebOct 1, 2024 · Of note, as iron uptake primarily occurs in the proximal small intestine, patients that have their colon resected (colectomy) exhibit normal systemic iron levels, unless complications arise. For example, pouchitis is a complication resulting from the ileal pouch-anal anastomosis created during colectomy of UC patients ( Ferrante et al., 2008 ).
