Serum Haptoglobin-MMP9 Complexes in Cattle

The purpose of this study is to verify the utility of the presence of a white blood cell protein complex that is released during serious bacterial infections. The goal is to obtain serum samples from cattle with a variety of conditions to ensure that the serum protein complex is only present in very ill animals and not in animals with less severe diseases. If determined that this is a sensitive and specific marker of infection in cattle, the test may be adapted to a patient side test allowing for early administration of effective antibiotics.
