Studies of Exclusive e+e- -> hadrons Reactions with Baryons and Strange Particles Using Initial State Radiation at Babar

New Babar results on exclusive e+e- -> hadrons reactions at low c.m. energy with a baryon-antibaryon or K\bar{K} pair in the final state are presented. Cross sections are measured using the initial state radiation technique from the threshold up to 4--5 GeV. From the measured e+e- -> proton\antiproton, Lambda\Lbar, Sigma0\Sigbar0, Lambda\Sigbar0(Sigma0\Lbar) cross sections we derive effective baryon form factors and compare them with predictions. We measure the K\bar{K}\pi(\eta), K+K-\pi\pi, K+K-3\pi, K+K-4\pi, K+K-K+K- final states and also study their internal structure. A new Y(2175) state is observed in e+e- -> K+K-f0(980), with f0\to\pi\pi. The total measured e+e- annihilation cross section into final states including strange baryons or strange mesons is estimated to be 10% of the full hadronic cross section.
