In this talk we report on the use of a chiral unitary approach for the interaction of the octets of meson and baryon and the octet of mesons with the decuplet of baryons. Two octets of J(pi) = 1/2(-) baryon states and a singlet are generated dynamically in the first case, resulting in the case of strangeness S = -1 in two poles of the scattering matrix close to the nominal A(1405) resonance. In the second case many resonances are also generated, among them an exotic baryon with S = I corresponding to a Delta K resonance. We make suggestions of experiments which could show evidence for the existence of these states.
