[Plasma fibrinogen as a parameter of the presence and severity of inflammation in horses and cattle].

Determination of the plasma fibrinogen concentration was found to be particularly useful in detecting inflammatory diseases. The highest levels were observed in inflammatory lesions of serous surfaces and in endocarditis. Plasma fibrinogen levels correlated with the severity of the disease: levels of 1,000 mg per 100 ml or more reflected a prognosis ranging from poor to bad.
