Abstract: Provided are methods and compositions for predicting the development of kidney disease, including acute kidney injury. In certain aspects and embodiments the provided methods and compositions are particularly useful for predicting kidney injury following an event likely to cause kidney injury and/or kidney failure in a patient, such as a cardiac surgery, e.g., a surgery involving a cardiopulmonary bypass (CPB), such as a coronary artery bypass graft surgery. In some embodiments, the higher the urinary hepcidin-to-urinary creatinine ratio (uHep/uCr) at 6-24 hours following initiation of CPB, the lower is the risk for development of AKI determined by RIFLE criteria in the ensuing four to five days. Conversely, the higher the urinary NGAL to urinary creatinine ratio (uNGAL/uCr) at 6-24 hours following initiation of CPB, the higher is the risk of developing CPB-mediated AKI over the same time period.

Abstract: The invention provides compositions and methods for measuring human serum hepcidin levels. The invention provides methods for the oxidative refolding of a hepcidin polypeptide to a form that is mature, bioactive and folded as in the native configuration and molecular mass; a method for measuring the level of native, bioactive hepcidin in a vertebrate animal.

Abstract: The present invention concerns a method for the oxidative refolding of a hepcidin polypeptide to a form that is mature, bioactive and folded as in the native configuration and molecular mass; a method for measuring the level of native, bioactive hepcidin in a vertebrate animal; a method for measuring the level of hepcidin gene expression in a vertebrate animal; and a method for regulating the production of native, bioactive hepcidin in a vertebrate animal in vivo. The present invention also concerns an antibody or fragment thereof that specifically binds to a continuous, discontinuous, and/or conformational epitope of a mature and bioactive hepcidin folded as in the native configuration; and a pharmaceutical composition that includes the antibody or a hepcidin polypeptide and that provides antimicrobial, agonistic, or antagonistic activities in vivo in a vertebrate animal.

Abstract: The present invention relates generally to the identification of virulence factors from Streptococcus iniae. Specifically, the present invention relates to the identification, characterization and sequencing of a gene for phosphoglucomutase gene, and to a live attenuated strain of S. iniae deficient in phosphoglucomutase useful as a vaccine in aquatic species, such as fish.
