We present cosmological parameter constraints obtained from galaxy clusters identified by their Sunyaev-Zeldovich effect signature in the 2500 square-degree South Pole Telescope Sunyaev Zeldovich (SPT-SZ) survey. We consider the 377 cluster candidates identified at z > 0.25 with a detection significance greater than five, corresponding to the 95% purity threshold for the survey. We compute constraints on cosmological models using the measured cluster abundance as a function of mass and redshift. We include additional constraints from multiwavelength observations, including Chandra X-ray data for 82 clusters and a weak lensing-based prior on the normalization of the mass-observable scaling re..
