PARASITISM INFLUENCE UPON THE PLASMATIC HAEMOSTASIS INDEXES IN CATTLE

摘要

The accomplished research show that the acute alteration of plasmatic haemostasis does not exceed the pathologic conditions of parasitosis. The results of laboratory parasitologic investigations established an invasion extensity with Eimeria spp. of 68%, S. papillosus 62%, D. lanceolatum 29%, E. granulosus larvae 45%. The parasitic association between S. papillosus and D. lanceolatum induce in the host organism the diminishing of prothrombin index caused by gastrointestinal diseases and by hepatic injuries these modifications, at their turn, perturb the hepatic synthesis of the proteins, including coagulation factors, thus, inducing the deficiency of vit. K, that is necessary for the hepatocytes for prothrombin gama-carboxylation, as well as of factors III, IX and I. Fibrinogen increasing would indicate an acute stage of parasitic and infectious inflammations. The above mentioned modifications are the result of allergic processes, of tissular destruction and degradation, appeared as a consequence of mechanical and rapacious action produced by parasites and bacteria.
