ACO1 and infection: Therefore, their expression favors bacterial colonization [16], while the expression of siderophore genes, such as enterobactin (entB), yersiniabactin (irp1, irp2, fyuA, and ybtS), salmochelin (iroN) and aerobactin (iutA), allowing for iron uptake and facilitating survival and bacterial multiplication during infections [17], while the expression of the cnf-1 and hlyA toxin genes promote the degradation of the host tissues, facilitating bacterial dissemination [18].
