RESUMO
Salmonella typhimurium responds chemotactically to gradients of divalent cations in the presence of citrate ions. The actual chemoeffector is the citrate-metal ion complex, which acts as an attractant. Citrate (which is also a chemoeffector for Salmonella) and the citrate-metal ion complex are recognized by different receptors. The response of Salmonells, which can transport citrate through its membrane, is quite different than that of Escherichia coli, which cannot.
